This column covers news received in July and August.
On August 14, Scott caught stunning satellite images of smoke settling in western mountain valleys and blowing away later in the day.
NOAA researcher Elaine Prins talked with WNWC radio reporter Gordon Govier about how the western wildfires might affect Wisconsin weather. In her research and that of her university collaborators Joleen Feltz and Chris Schmidt, Elaine uses GOES data to observe fires and smoke. Elaine told the reporter that thicker smoke (optically) can reduce temperature at the surface by 3–5 degrees, but that Wisconsin probably experienced much less of an impact, about 1–2 degrees cooler. It is also possible, she said, that, because forecast models do not account for smoke, surface temperature forecasts can be up to 5 degrees too high for optically thick smoke. While preliminary research findings indicate that smoke can result in reduced precipitation, it probably did not have that effect in Wisconsin.
Scott and Elaine and their colleagues continue to track wildfires and their smoke and its effects. Watch the GOES Gallery.
Elaine and Chris Schmidt produced experimental products to monitor wildfires in Quebec in collaboration with M. Moreau of Environment Canada. Satellite imagery was placed on the Web in real time. This year, the wildfire product from GOES data is being compared to data from NOAA’s polar-orbiting satellite in near real time to assess the advantages and disadvantages of each instrument for fire detection and monitoring. Although the fire season in Quebec was slow this year, the wildfire product detected several fires including a small fire on June 19 which was not detected by the polar-orbiting satellite due to cloud cover at overpass times.
The fire researchers are also producing fire products for the 2000 South American fire season. Several groups of U.S. and South American scientists will use the products in fire validation studies, climate change modeling activities, and emissions modeling.
Watching VolcanosSaskatchewan Education’s online curriculum links to SSEC’s Volcano Watch “as a valuable educational resource.” The site is multiple levels deep and many different school systems link from it. Volcano Watch is hidden in “A Curriculum Guide for the Middle Level - Grade 6 Activity” and may be elsewhere.Research Central, a Web site operated from London, Ontario, Canada, links to SSEC’s Web site for Volcano Watch. Research Central labels itself as a “free, central starting point for anyone doing research on the Internet.” SSEC is listed under Current Events, Weather.
Drilling IceLatest in SSEC’s Antarctic projects is the Ice Drilling and Coring Service, mentioned in the July 30 Milwaukee Journal Sentinel. In his article, Ernie Mastroianni said that the five-year contract, managed at SSEC by Bob Paulos, “covers all National Science Foundation ice coring and drilling projects at high latitudes and high altitudes, which include polar areas such as Antarctica and Greenland and high mountain ranges.” Charles Bentley, emeritus professor in Geology and Geophysics, serves as the project’s principal investigator. SSEC has begun to receive and store ice-coring equipment. NSF has selected Ernie Mastroianni for its visiting media program to the South Pole this southern summer. He will visit SSEC and other researchers while there.
Photographing SnowflakesThe Board of Friends of UW–Madison Libraries voted a small grant to The Schwerdtfeger Library to preserve and conserve Wilson “Snowflake” Bentley’s lantern slides of snow crystals. Librarian Jean Phillips is “excited not only about their preservation but making them more accessible to our users.” In January, as part of an exhibit in several campus libraries, The Schwerdtfeger Library acquired prints and lantern slides by the first snow crystal photographer. This grant enables permanent access and preservation of the unique collection. The Friends of UW–Madison Libraries began awarding small grants through competition in 1997 and have granted nearly $75,000 to campus library units.
Tracking IcebergsMuse, a children’s science magazine, will feature icebergs in their December issue. Matthew Lazzara worked with authors on a story that will include B-15, B-16 and all the other icebergs in the Ross Sea that Matthew has monitored since March. Muse is a joint publication of the Cricket magazine group and the Smithsonian Institution.Weather-wise.com, an Australian weather site, reports on the Ross Sea icebergs in a long article with many facts and scientists’ suppositions, and satellite images provided by the AMRC. History is provided, showing why the Ross Ice Shelf was due to calve icebergs.
Watch for the October issue of Discover magazine. Karen Wright interviewed Matthew Lazzara about the icebergs and he supplied some images. The magazine is available on news stands mid-September.
Contributing to Polar MeteorologyIn July, Links2Go selected Chuck Stearns’ Antarctic Automatic Weather Stations and the Antarctic Meteorological Research Center Web sites as “Key Resources” in polar topics. Of the 50 pages selected as Key Resources for the polar topic (key resources are those sampled most often), the AWS page ranked 39th and AMRC 40th. Links2Go “provides online businesses and end-users with search and directory services.” The heart of their business is a large topical directory of the Internet.The AMRC is listed in Web Resources in Peter Guest’s Polar Meteorology modules, on the Naval Postgraduate School’s Web site. Peter especially likes the composite satellite imagery.
On SAFARISSEC’s Dan LaPorte and Hank Revercomb made the Johannesburg, South Africa’s Sunday Independent for August 20. A photo of the pair was featured in a long article about the Southern African Regional Science Initiative field experiment, SAFARI 2000, now underway. SSEC’s Scanning-High resolution Interferometer Sounder, its crew and SSEC researchers are taking measurements from NASA’s high altitude research aircraft, the ER-2. The measurements over the southern African landscape will be compared with instruments on NASA’s earth observing satellite Terra. NASA and its collaborators hope that SAFARI measurements taken during the southern African dry season will “improve the ability of new instruments on Terra to monitor active fires, map ‘burn scars’ eft after the fires, and measure the amount of carbon monoxide in the lower atmosphere.”
SSEC director and Scanning-HIS principal investigator Hank Revercomb explained Africa’s climate: “The African land mass is a giant gyre in its circulation. With a perpetual high over the continent, smoke from power plants and brush and farm fires can’t escape. The Scanning-HIS and measurements from the other instruments will help us learn how to detect smoke and accompanying carbon monoxide signatures.” SSEC is looking particularly at the MODerate-resolution Imaging Spectrometer (MODIS), an instrument SSEC helped develop, and the Canadian instrument, Measurements Of Pollution In The Troposphere. As its name implies, MOPITT measures carbon monoxide and methane in the troposphere. The research teams of MOPITT principal investigator James Drummond, University of Toronto, and Hank Revercomb will compare different techniques to detect trace gases, including carbon monoxide.

To make satellite data more useful for weather forecasters, researchers often “correct” the data with software. Recently, such a correction was added to the suite of data processing software for the sounder instrument on the GOES-11 satellite to handle “sun glint.” At certain times and locations there is additional specular reflected solar radiation in the satellite’s sounder data due to the geometry of sun and satellite. Tony Schreiner (SSEC) and Tim Schmit (NOAA) provided this software modification to NOAA’s Forecasts Product and Development Team.

Researcher Jeff Key (NOAA) has produced a 40-year climatology of cyclonic systems at 1000 mb and 500 mb levels. Cyclones were identified with an automated procedure using geopotential height fields from the National Centers for Environmental Prediction and the National Center for Atmospheric Research. The data set consists of cyclone locations and tracks over the 40-year period. This data has been used to analyze trends and can also be used to formulate climatologies of cyclone frequencies, cyclogenesis, and storm tracks.

Weather-wise.com used an animation by the Tropical Cyclones group in its August 2 story on Tropical Storm Daniel. The storm threatened the Hawaiian islands and the Kenwood Cup. It threatened the sailing race with lack of wind! Norbert Ueberuck, a Web provider in the Dominican Republic, praised the Tropical Cyclones group: “As Hurricane Georges in 1998 hit us very hard, without receiving early warning from the local news channels, since 1998 I only trust you guys, and you did not fail yet.” Former Tropical Cyclones group member Jason Dunion is now with NOAA’s Hurricane Research Division. He recently thanked the group for wind measurements they provide during hurricane season. Jason generated his own surface map showing different sources of wind measurements.

In June, John Young and Scott Lindstrom reported on Wisconsin’s record-breaking rainfall. Scott’s statistics were used in an article in the Milwaukee Journal Sentinel for June 15. Scott used records from Madison’s airport, which showed that “15.27 inches of rain fell in the 30 days ending at midnight Wednesday [June 14], making that the wettest 30-day period in the last 50 years.” The article focused on the havoc wreaked in Dane County and southern Wisconsin. David Medaris of Isthmus, Madison’s weekly newspaper, wrote a lively and informative piece for the July 21 issue. David used those same statistics and reminded readers that the State Climatologist’s Office serves up all sorts of weather records, just like those that Scott used. The journal Polar Geography will include a note and pictures on the recent Ross Ice Shelf calvings. The Antarctic Meteorological Research Center provided the editor with satellite images of all the new (since March) icebergs.

Thanks to NOAA and UW–Madison researchers collaborating at the Cooperative Institute for Meteorological Satellite Studies, teachers and students can now receive products from the GOES sounding instrument. Through the Unidata program, university researchers and educators can acquire and use atmospheric and related data on their own computers in class and in projects. Gary Wade (NOAA) and his federal and university colleagues made GOES products available in early July to the Unidata community; products include sounder-derived product imagery of total precipitable water and ozone, atmospheric stability (lifted index and convective available potential energy) and sea surface temperature, derived from cloud-top pressure and imager data. UW–Madison and NOAA hope to gain feedback on the utility of GOES derived products from a wider segment of the weather science community. The National Science Foundation funds the Unidata program, which is maintained by the University Corporation for Atmospheric Research.
Shane Mayor’s poster presenting UW–Madison’s lidar research was pronounced best student poster, out of about 40 posters at the 14th Symposium on Boundary Layers and Turbulence, held recently in Aspen, Colorado. The poster is displayed on the 9th floor of the Atmospheric, Oceanic and Space Sciences building. Other poster authors are Greg Tripoli (AOS) and Ed Eloranta (SSEC & AOS).

High layers of smoke apparently from western wildfires blew over Wisconsin on August 9. Invisible to the naked eye, the elevated layers could only be seen in radar images. Scott Bachmeier in SSEC’s Cooperative Institute for Meteorological Satellite Studies (CIMSS) put them on the GOES Gallery Web site with corresponding satellite images. Earlier that day, before discovering the radar, Scott spoke to the Madison-based representative of the Appleton Post Crescent about effects of the wildfires on Wisconsin weather. It seemed there were few.
