CAMEX-3 status report
August 13, 1998: (This is the second in a series of stories covering the ongoing CAMEX mission to hunt hurricane data in a way not done since the 50s. Other stories are linked in below.)
Thursday morning, weather researchers from across the country met to talk about the first mission of the experiment that could improve hurricane forecasting and validate measurements from the Tropical Rainfall Measuring Mission (TRMM).
Since no hurricanes or tropical storms were brewing in the Atlantic, the meeting concentrated on the TRMM validation portion of the experiment.

Note: More details are available in the NASA press release describing CAMEX-3. Check back as hurricane season progresses. We will post science updates as the campaign develops.

NCAR has an extensive writeup on the GPS dropsondes used in CAMEX-3 and other atmospheric campaigns.
A new study - not related to CAMEX-3 - by the Arizona State University suggests a link between hurricanes in the northwest Atlantic and air pollution.
Today at 2 p.m. EDT, NASA's ER-2 and DC-8 (left) are scheduled to take off from Patrick Air Force Base, Fla., to collect high-altitude thunderstorm rainfall and lightning measurements.
Information gathered from the mission will help calibrate measurements from the rainfall measuring satellite. TRMM is a joint NASA and Japanese National Space Development Agency mission to measure rainfall 35 degrees above and below the equator.
Today's short two-hour flight also will allow the researchers to check out their communication systems and instruments.
CAMEX-3 is an interagency project to measure hurricane dynamics at high altitude. From this, scientists hope to understand better how hurricanes are powered and to improve the tools they use to predict hurricane intensity.
An overview story (Aug. 12, 1998) describes the program in detail. The study is part of NASA's Earth Science enterprise to better understand the total Earth system and the effects of natural and human-induced changes on the global environment.
