Brightness Increases<\/a><\/strong>\u2014Larry Sromovsky and other scientists used the Hubble Space Telescope to observe Neptune in 2002. Building on previous observations, they revealed significant increases in Neptune\u2019s brightness over the years. Their analysis indicates that seasons occur on the planet and that spring has come to Neptune\u2019s southern hemisphere.\u00a0Icarus<\/a>,<\/em>\u00a0the journal of planetary science, published their paper in volume 163, issue 1, (May 2003), pages 256\u2013261. Besides Sromovsky, the paper\u2019s authors are Pat Fry and Sanjay Limaye of SSEC and Kevin Baines of NASA\u2019s\u00a0Jet Propulsion Laboratory<\/a>. Terry Devitt, science editor in UW\u2013Madison\u2019s Communications office, released the\u00a0news<\/a>\u00a0concurrently with the Space Telescope Science Institute on 15 May, when it ran on the\u00a0STScI<\/a>\u00a0front page. On the\u00a0University News<\/a>\u00a0Web site, images and a movie are posted.\u00a0EurekAlert!<\/a>, the Web-based science news organization, and the\u00a0Science Blog<\/a>\u00a0released Devitt\u2019s report on 15 May.\u00a0Wisconsin Week Wire<\/em>\u00a0published the news on 21 May.<\/p>\n\n\n\n

Media around the world immediately used the story. Perhaps they were cheered by news of such a far away spring. The\u00a0Wisconsin State Journal<\/em>\u2019s Anita Clark featured Sromovsky on the front page, local section (May 15), and emphasized Neptune\u2019s mysterious and puzzling nature. In \u201cScience Times\u201d (Tuesday, May 20), the\u00a0New York Times<\/em>\u00a0published colored images from three years, showing the increase in brightness.USA Today<\/em>\u00a0(\u201cA better Life\u201d column, 19 May) showed an image from the brightest year in black and white, with a summary of the most interesting facts.\u00a0UPI<\/a>\u00a0(16 May) and\u00a0Aviation Week & Space Technology<\/em>\u00a0(2 June) also summarized the findings, and noted that the progressive brightening of Neptune\u2019s cloud bands is \u201can apparent response to seasonal variations in sunlight,\u201d although Neptune is very far from the sun.<\/p>\n

The\u00a0New Scientist<\/a><\/em>\u2019s Will Knight (15 May) noted Neptune\u2019s extreme variations from Earth\u2019s norm\u2014Neptune\u2019s axis is tilted like Earth\u2019s, but seasons last 40 years; the average surface temperature is \u2013218 \u00b0C; winds travel at up to 1500 km an hour. Astronomer James O\u2019Donnell at Greenwich, England\u2019s Royal Observatory \u201csays the latest findings may help planetary scientists better understand how this peculiar heating process and solar radiation combine to control the surface conditions on Neptune.\u201d The\u00a0London Times<\/em><\/a>\u00a0on 19 May also noted that \u201cNeptunian versions of spring, summer, autumn and winter are very different from their counterparts on Earth.\u201d<\/p>\n

The\u00a0Milwaukee Journal Sentinel<\/a><\/em>\u2019s Susanne Quick (Sunday, 25 May) noted that the seasonal observations were based on Sromovsky\u2019s study of Saturn\u2019s moon, Titan. In that article, astronomer Heidi Hammel, Space Science Institute in Connecticutt, noted that Sromovsky\u2019s conclusions differ from hypotheses by other scientists.<\/p>\n

Ron Cohen, for\u00a0Science News<\/em>\u00a0(24 May), also spoke with Hammel and G. Wesley Lockwood of the Lowell Observatory in Arizona. All three scientists \u201cagree that seasonal variations may only be part of the explanation for Neptune\u2019s remarkably dynamic atmosphere.\u201d Hammel noted that verification of Sromovsky\u2019s seasonal hypothesis \u201cwill send atmospheric dynamicists into a tizzy trying to explain how it could possibly be.\u201d<\/p>\n

Deborah Zabarenko wrote for\u00a0Reuters<\/a>\u00a0News Service (16 May) that Neptune\u2019s southern hemisphere spring meant \u201c40 years of bright clouds.\u201d She explained that, like Earth, Neptune\u2019s axis tilts, and it is the south that is tilting toward the sun. Her release was used on 16 May by the\u00a0Houston Chronicle<\/em><\/a>,\u00a0Yahoo!News<\/a>,\u00a0abc News<\/a>, and\u00a0Houston Public Radio<\/a>. Covering the story and taking the opportunity to explain seasons wereStarrySkies.com<\/a>\u00a0(with a huge image of Neptune),\u00a0Scientific American.com<\/a>\u00a0(19 May),\u00a0Space.com<\/a>\u00a0(19 May),Astronomy.com<\/a>, and MSNBC News\u2019\u00a0Cosmic Log<\/a>\u00a0(16 May), in which Alan Boyle discussed the Neptunian seasonal shift and delved deeper into its mysteries. CNN.com ran the story on 17 May.<\/p>\n

The newspaper,\u00a0SpaceNews<\/em><\/a>, 2 June, published the news in its column, \u201cSpaceLog,\u201d with outsize pictures of the planet\u2019s southern hemisphere to show the brightness difference over time. Neptune was front page news on\u00a0NASA\u2019s Web site<\/a>, 3 June. Beth Beck stressed the differences in spring on Neptune and Earth.<\/p>\n

Data, Imagery, Software<\/em><\/h1>\n

Wisconsin MODIS image<\/strong>\u2014The National Weather Service Office in Sullivan featured this image of haze over Wisconsin as Top News of the Day on 7 May. The haze appeared to be smoke from Russian fires, although a big fire did occur in northern Saskatchewan on Sunday afternoon, 4 May. However, the smoke plume from the Canadian fire was advected northeastward toward Hudson Bay. This image was received and processed at SSEC. The striping seen over Lake Michigan is an instrument artifact that is visible in bright water scenes, particularly in cases of sun glint, such as in this image.<\/p>\n

Towards Making Satellite Data More Useful More Quickly<\/a><\/strong>\u2014The NRC report to which Chris Velden contributed is now available from the National Academies Press. NASA and NOAA initially commissioned the report and have applauded the authors\u2019 recommendations.<\/p>\n

Rainrate Measured, Animated<\/strong><\/a>\u2014Grant Petty (AOS and SSEC) and his research group developed an algorithm to retrieve rainfall from the AMSR and AMSR-E passive microwave imagers deployed on Japan\u2019s Adeos-2 and the U.S. Aqua satellite, respectively. The algorithm was used for the first public release of microwave-derived rain rate images, based on a series of observations of Typhoon KUJIRA as it moved westward across the tropical Pacific toward Taiwan during the period 11\u201321 April. Using the two Advanced Microwave Scanning Radiometers together it is now possible to track the evolving rainfall patterns in a typhoon over open ocean with unprecedented continuity and detail over several days, as is clearly shown in the\u00a0animation<\/a>.<\/p>\n

Earth Observatory<\/strong><\/a>\u2014This popular NASA Web site has won the 2003 Webby Award, as well as a people\u2019s choice award. Web site administrator David Herring congratulated all Earth Observatory partners, which include SSEC. The MODIS group often provides images, while Tom Whittaker and other programmers provide software tools.<\/p>\n

Internet2<\/strong>\u2014The\u00a0Chronicle of Higher Education<\/em>\u00a0featured Internet2, * the network that \u201chas transformed higher education\u201d with \u201cits ability to transmit enormous amounts of data in fractions of seconds \u2026 .\u201d Its impact has been felt most on research and engineering articles, wrote Florence Olsen, who said that Internet2 is at a crossroads. The current economic slump may mean that the network cannot grow or become faster, which will be necessary to keep up with ever increasing research demands and just to improve how \u201capplications work on Internet2 networks.\u201d Or, as Ronald Trewyn, vice provost for research at Kansas State University put it, \u201cAs soon as you put in a bigger pipe, you need the next bigger one.\u201d Pressures to upgrade, costs of doing so, and possible improvements are all discussed in the article. A few applications that use Internet2 are mentioned, including Steve Ackerman\u2019s class, \u201cIntroduction to Weather and Climate.\u201d Ackerman, a professor in UW\u2013Madison\u2019s Department of Atmospheric and Oceanic Sciences, also directs SSEC\u2019s CIMSS.<\/p>\n

The IHOP_2002 Newsletter<\/strong><\/a>, which reports on last year\u2019s water vapor experiment, has published the article, \u201c12 June 2002 Rapid Water Vapor Transitions during the IHOP Field Program,\u201d by Wayne Feltz, Derek Posselt, and John Mecikalski (CIMSS) and Gary Wade and Timothy Schmit, (NOAA\/NESDIS, stationed at SSEC). The article reports on an analysis of a water vapor \u201cevent,\u201d which would not have been \u201cdetectable by surface moisture observations, and could only be resolved with high temporal remote sensing capability,\u201d such as SSEC\u2019s Atmospheric Emitted Radiance Interferometer.<\/p>\n

Connecticut Woodlands<\/em><\/strong><\/a>\u2014SSEC provided a GOES image to this magazine to illustrate an article on climate change. (NOAA is credited.)

Natural Hazards<\/strong><\/a>, a publication of NASA\u2019s Web site, Earth Observatory, published a MODIS image from the Aqua satellite showing dust blowing up from Mexico into the United States. SSEC\u2019s direct-broadcast facility provided the true-color image on April 15.<\/p>\n

The Weather Network<\/strong>\u00a0(Canada\u2019s equivalent of\u00a0The Weather Channel<\/em>) in Toronto used animated Terra MODIS imagery of ice cover on the Great Lakes this spring. On-air meteorologist Christopher Scott used the images in an in-depth segment where high-resolution imagery highlights the science. Paraphrasing Scott Bachmeier, Scott said, \u201cyou could actually see the ice \u2018move\u2019 throughout the day.\u201d SSEC\u2019s CIMSS was credited.<\/p>\n

The National Academies\u2019 National Research Council<\/strong>\u00a0has published\u00a0Neutrinos and Beyond<\/em><\/a>: New Windows on Nature,<\/em>\u00a0which features IceCube and AMANDA. Published by the NRC\u2019s Board on Physics and Astronomy, the report lucidly explains how the discovery that neutrinos have mass has \u201cspurred proposals for new initiatives.\u201d The report compares IceCube, the international neutrino telescope project at the South Pole led by UW\u2013Madison, with \u201ca new deep underground laboratory\u201d in the U.S. The Board concludes that the two facilities are distinct. Furthermore, \u201cIceCube is unique in its technology and location and is the most advanced project for high-energy neutrino observation on this scale.\u201d A\u00a0summary<\/a>\u00a0is available; the whole report is attractively priced and can be purchased on the\u00a0Web<\/a>.<\/p>\n

Tropical Cyclones<\/em><\/h1>\n

A forecasting technique<\/strong>\u00a0developed in UW\u2013Madison\u2019s CIMSS Tropical Cyclones group is featured inSpaceNews,<\/em>\u00a02 June 2003. Researchers have known for 30 years that air masses from the Sahara can \u201ccause some hurricanes to weaken in defiance of computer models.\u201d As a student working for CIMSS, hurricane forecaster Jason Dunion, now at the University of Miami assigned to NOAA\u2019s Hurricane Research Division, developed a tracking technique using GOES infrared readings. Airplanes will collect data during this hurricane season to test the tracking technique. GOES imager data will be posted on the CIMSS\u00a0Tropical Cyclones<\/a>\u00a0Web site throughout the test.

Italian TV<\/strong>\u2014Representatives of the National Italian Television science program, \u201cSuperquark,\u201d visited Madison in April to interview Paolo Antonelli and Giulia Panegrossi, meteorologists from Italy who live and work here with their two young sons. The segment, planned for the forthcoming season, will feature the two scientists at work and home. SSEC has been promised a tape when the show airs.<\/p>\n

Weather Guys<\/strong><\/a>\u2014Steven Ackerman and Jonathan Martin shifted their normal WHA Radio appearance date to Tuesday, 27 May, because of holiday programming on 26 May. With Jim Packard hosting for Larry Meiller, they talked mostly about severe spring and summer storms, including the requisite lightning experiences\u2014a tractor driver graphically described how he lost a finger in a thunderstorm. He was urged not to touch metal in his cab during a storm. A woman called in with her own lightning experience and was treated to a detailed explanation. Packard nudged the program toward environmental phenomena, like the length of days in Alaska and the lunar eclipse. He continued to press for lightning information, resulting in more calls about the phenomenon. The show ended with a geological question about whether Mt. Ranier would erupt soon. The Guys, being meteorologists, were unable to answer the question, but Jim promised they\u2019d have the answer for the next show. The Weather Guys programs are archived (since February 2002) on Larry Meiller\u2019s Wisconsin Public Radio\u00a0Web pages<\/a>.

Weather Research<\/em><\/h1>\n

Clear Sky Products<\/strong>\u2014A large part of the research mission of the Cooperative Institute for Meteorological Satellite Studies (CIMSS) at UW-Madison is developing useful products from weather satellite data and making them available for use in weather forecasts and research. With the recent move of the GOES-9 satellite to the western Pacific, Tony Schreiner (CIMSS) and Tim Schmit (NOAA) are now producing hourly Clear Sky Brightness Temperature information for Imager instruments on GOES-9, -10, and \u201312. These new data, along with data currently generated from GOES-10 and GOES-12, will be utilized in global forecast models at the European Centre for Medium-range Weather Forecasts (ECMWF) and the U.S. National Centers for Environmental Prediction (NCEP).<\/p>\n\n\n\n

Data from the GOES-9 Sounder instrument is being received over the western Pacific and is being archived. A sample\u00a0loop<\/a>\u00a0of the GOES-9 Sounder data is available.<\/p>\n

Special GOES Movie<\/a><\/strong>\u2014On May 19, Rick Anthes, University Corporation for Atmospheric Research, spoke to Congressional staffers from the Senate Committee on Commerce, Science and Transportation and the House Committee on Science. To show the need for high spatial resolution images, Tim Schmit (NOAA, at SSEC) and Tom Whittaker (CIMSS) provided data loops showing progressive averaging for GOES Imager infrared images.<\/p>\n

GOES-9 on Duty<\/a><\/strong>\u2014On May 22, GOES-9 replaced Japan\u2019s Geostationary Meteorological Satellite (GMS) at 155 East longitude. A variety of products and procedures were put in place for GOES-9. Gary Wade (NOAA, at SSEC) made available all GOES-9 Sounder bands in near-real time as\u00a0day-long animations<\/a>\u00a0on the CIMSS Web page. The hourly schedule for the GOES-9 Sounder provides for three sectors, with coverage for the central (including Papua New Guinea) and southern (including eastern Australia) available every six hours while northern (including Japan) coverage is available for the remaining 16 hours. Sounder derived products, such as total precipitable water, are now being produced with broad coverage in the mid latitudes over the Pacific Ocean and U.S. Real-time GOES-9 (formerly GMS), GOES-10 (-West), and GOES-12 (-East)\u00a0imagery and products<\/a>\u00a0are displayed on the CIMSS Web page. Sector scheduling among the three GOES satellites provides for optimal coverage over this wide area for only 12 out of 24 hours, although U.S. coverage remains hourly.<\/p>\n

With NOAA\u2019s Forecast Products Development Team,<\/strong>\u00a0the CIMSS Winds Team developed and helped implement new winds code that utilizes GOES-9 imagery for wind measurements tracked in cloud features. The transition into operational winds production at both NESDIS and the Air Force Weather Agency went smoothly and routine datasets are now being produced and disseminated to users.<\/p>\n

The CIMSS GOES sounder team<\/strong>\u00a0of Jim Nelson and Tony Schreiner (CIMSS) and Gary Wade and Tim Schmit (NOAA) is producing GOES-9 vertical profiles of temperature and moisture from Sounder information over the western Pacific Ocean. They are also generating Derived Product Images (DPI) of Lifted Index (LI), Total Precipitable Water (TPW<\/a>) vapor and surface skin temperature.<\/p>\n

Education, Outreach<\/em><\/h1>\n

PEOPLE Progress<\/strong>\u2014UW\u2013Madison\u2019s PEOPLE Program for 2003 started Monday, June 9th, and students participating in the \u201cAviation and Space\u201d workshop were thrilled with the first day of their summer experience. Michael Mcardle, a hot air balloonist and retired Madison East High School teacher, offered tethered balloon rides to 14 middle school students in Quann Park, close to UW Space Place, where the rest of the workshop is held.<\/p>\n

PEOPLE (Pre-college Enrichment Opportunity Program for Learning Excellence) seeks to increase college enrollment and graduation of ethnic minority students by reaching out to them in middle and high school. SSEC\u2019s Office of Space Science Education has participated in the PEOPLE program since it began in the summer of 2000. The Space Exploration workshop added the Aviation component through a collaboration with the Wisconsin Department of Transportation with Karen Valley’s help. This has added a fun-filled week of aviation experiences, including a trip to the EAA in Oshkosh. This workshop continues to offer interesting and challenging lessons on space travel, the solar system and rockets. This year, to mark the launch of three spacecraft towards Mars this month and the close approach of the Red Planet to Earth in August, the workshop will feature Mars Exploration.<\/p>\n
