Hudson Bay freezes every year around this time. This year, the
MODIS instrument on board NASAs Terra earth science satellite enables
us to watch the process. Scott Bachmeier of SSECs Cooperative Institute
for Meteorological Satellite Studies (CIMSS), who maintains the GOES Gallery
on the CIMSS Web site, has animated images received through SSECs
rooftop antenna. Bachmeier warns that the images are large: Your monitor
should be set at 1024x768 or higher. The image loop will keep accumulating
daily images until Hudson Bay is completely frozen.

Weather recordsWisconsins unseasonably warm weather made local and regional news. Comparing data recorded at Madisons local airport, Truax Field, SSECs Scott Lindstrom found that November 2001 was the warmest on record here. The mean temperature of 46.0° F was more than 10 degrees above normal. University Communications released the findings as a news tip and Lindstrom was interviewed for Madisons WISC-TV Channel 3 on a balmy Sunday afternoon with roses blooming in the background. The piece aired Sunday night, December 16. WIBA radios Josh Wescott interviewed Lindstrom and he was quoted in Madisons Capital Times newspaper (December 18). Madisons temperature rose to 64° F on December 5, the warmest recorded Madison temperature on that day. On December 26, winter finally arrived in Madisonthe high was 18° F.
AnniversarySteve Ackerman (CIMSS director and UWMadison Department of Atmospheric and Oceanic Sciences) and John Knox (University of Georgia, Department of Atmospheric Sciences) were interviewed on WCCO-AM, a Minnesota radio station, early Saturday morning on the anniversary of the sinking of the ore ship Edmund Fitzgerald. The ship sank on November 10 in 1975 in the worst shipping disaster on the Great Lakes in the preceding 11 years. Ackerman and Knox explained the dreadful weather conditions and their effect on the ship.
Weather Guys Steve Ackerman and Jonathan Martin, UWMadison Department of Atmospheric and Oceanic Sciences, appeared Monday, December 31 on Larry Meillers WHA Radio call-in show. Jon Martin explained the long period of warm weather in Wisconsin as a persistent southwesterly flow. It made this December, even with the last week of seasonably cold temperatures, 9 or 10 degrees above normal. They talked about reviewing data for trends. Steve Ackerman fielded questions on optical phenomenarings (coronas) around the moon, why the sky is blue (the cleaner the air, the bluer the sky). Martin, who wouldnt mind living in Buffalo, NY, explained why so much snow fell on that city at one timeExtreme lake effect snow is enhanced by persistent upper level processes. The Weather Guys appear next on January 28. WHA Radio is at 970 AM and on the Internet. Click on Live Ideas Network Webcast.
Japanese television viewers soon will see satellite imagery and analyses produced by the CIMSS Tropical Cyclones group. WeatherNews Inc., with offices around the world, will use them in Chiba City, close to Tokyo, Japan. Meteorologist Masako Konishi said that their station referred to the Web site images during cyclone season and found them very useful. Now theyd like to use the images on the air with credit to CIMSS. Japans WeatherNews television station has 2.4 million viewers.

ABICIMSS and NOAA scientists stationed at UWMadison continue to provide input for the next generation of instruments for the U.S. Geostationary Operational Environmental Satellite (GOES). Tim Schmit and Elaine Prins (NOAA) propose a 15-band option for the Advanced Baseline Imager (ABI) consisting of the original 12 bands and three new bands centered at 0.47, 7.4, and 9.7 microns to better detect aerosols, moisture flow, sulfur dioxide, and total ozone and for multi-band color products,. An 18-band configuration would consist of the 15-band option plus bands at 2.1 and 3.7 microns for hot spot (fire) detection and cloud information, and a 0.55 micron band for a true green in color composites. Reserchers also supplied information regarding fire channel needs, including an evaluation of 3.9 micron maximum brightness temperature and noise requirements at both 1 and 2-km spatial resolutions.
GOES-12 TestDuring the recent science test of GOES-12, launched in July, the CIMSS cloud top pressure product was compared to that from other GOES instruments. In general, Tony Schreiner (CIMSS) and Tim Schmit (NOAA) found fair agreement among cloud top pressure products from the GOES-12 Imager, the GOES-12 Sounder, and the GOES-8 Sounder. Slight differences are due to different view angles, noise, time differences, and the lack of a 12 micron channel on the GOES-12 Imager that aids in low-cloud detection. The GOES Imager provides a finer spatial resolution product.
Fires 2001Elaine Prins (NOAA) and Joleen Feltz and Chris Schmidt (CIMSS), who monitor biomass burning with the GOES satellite, have released statistical results for the 2001 fire season in South America. Fire products made with their Automated Biomass Burning Algorithm (ABBA) for June through October 2001 indicate that the amount of burning was greater than in the 2000 fire season, but nearly 12% less than that observed on average over the past seven years. In 2001 nearly 300,000 fire pixels were detected with the GOES-8 ABBA at 11:45, 14:45, 17:45, and 20:45 UTC. These results are being used to characterize diurnal (daily), spatial, seasonal and interannual trends in fire activity throughout South America. The study area extends from 0 to 40°S and from 35 to 75°W and includes portions of Brazil, Peru, Bolivia, Paraguay, Uruguay, and northern Argentina.
and the National Environmental Satellite, Data, and Information Service
(NESDIS) are preparing for another GOES rapid-scan WINds EXperiment (GWINDEX)
to take place during the next Pacific Jet (PACJET) west coast field campaign
this winter (January - March, 2002). Chris Velden and Dave Stettner of CIMSS
with J. Daniels of NESDIS will produce GOES-10 winds from rapid-scan imagery
every 3 hours and will disseminate them to the National Weather Service
western region forecast offices and the Forecast Systems Laboratory for
Rapid Update Cycle (RUC) model assimilation. |
What do you use to illustrate weather around the world in color? SSEC's global montage, known in house as the color mollweide, for the map projection used. Two periodicals have printed the image-UW-Madison's alumni magazine, On Wisconsin (Winter 2001) and Discover magazine (December 2001). In Discover, the montage illustrates an article on a study by the National Center for Atmospheric Research (Colorado). Scientists looked at how much of the earth's heat is carried through its atmosphere and how much through the ocean. Incidentally, SSEC was founded on studies of Earth's heat budget and has collaborated other years with NCAR on this and other atmospheric research issues.
An image credited to CIMSS and NOAAs Hurricane Research Center (HRD) is used on the cover of the December 2001 Bulletin of the American Meteorological Society for the cover story on the accuracy of forecasting Atlantic Ocean hurricanes from 1976 through 2000. The HRDs Jason Dunion (formerly with CIMSS) collaborated with SSECs Rick Kohrs to produce the image.
In La Météorologie for May 2001, Verner Suomis role as father of satellites, père des satellites météorologiques, is noted in an article on Meteosat. He is given credit for his spin-scan camera invention, which made it possible to track the earths weather from space. La Météorologie is the journal of Frances meteorological society.

Wisconsin Alumni Association
is sponsoring a tour of Arizonas astronomical and other highlights.
Jim Lattis, UW Space Place director, and Sanjay Limaye, SSEC scientist who
directs its Office of Space Science Education, will guide the tour. The
tour will be held in April, when Arizona is sunny and warm, and will include
star parties and visits to astronomical sites like the WIYN telescope on
Kitt Peak. In one week, the group will visit space-related laboratories
at the University of Arizona in Tucson, the Arizona-Sonora Desert Museum,
Oak Creek and Grand Canyons, Sunset Crater National Museum and other star-studded
spots. Members of this small group tour will benefit from expert guidance
and have a rousing good time. For more information, contact the Alumni Association
at 888-922-87282 and ask about Cacti to Craters.
Sanjay Limaye gave one of two keynote speeches on Earth Reesrch Day held on November 16 at the Lac Courte Oreilles Ojibwa Community College in northern Wisconsin. On a day devoted to exploring environmental science and educational issues, Limaye spoke on Global Warming-Fact or Fiction and a Space Science Curriculum.
Project Kaleidoscope (PKAL) asked CIMSS Director Steve Ackerman to give the keynote speech at its National Assembly held in Madison in October. Appropriate to the meetings theme, Science at the Cutting Edge: Bringing Advances in Science and Technology into the Undergraduate SME&T Environment, spoke on the difficult task of integrating research with teaching. Ackerman combines teaching in UWMadisons Department of Atmospheric and Oceanic Sciences with his research in the Cooperative Institute for Meteorological Satellite Studies. He told the assembled professors not only of effectively bringing technology into his Meteorology 101 classes, at a much earlier level than usually attempted, but of prominently including student contributions into research projects. He focused on the CIRRUS project, which NASA had funded as a feasibility study. CIRRUS, the Cloud Infrared Radiometer for University-class Earth System Science (UnESS), would study ice clouds from the International Space Station. Students were involved in every activity, from designing and building the instrument to designing the project's logo.
In his PKAL talk Ackerman noted the delicate balance for him as a teacher and scientist, meshing both these roles and others. PKAL teachers work to build strong learning environments for undergraduate students in mathematics, engineering and the various fields of science. Ackermans CIRRUS project has not yet been funded as a full-scale project because UnESS was dropped from the NASA budget solely because of cost-cutting measures.
