After a decade
of preparation, the Atmospheric Infrared Sounder (AIRS) and its two companion
microwave sounders were launched in May 2002 on the NASA Aqua mission. Currently,
they are observing the Earth's weather and water cycle with unprecedented
detail. The AIRS sounding system measures atmospheric temperature and humidity
profiles worldwide and provides concurrent information on clouds, ozone and
other greenhouse gases. Compared to the only few thousand profiles of daily
weather balloons, AIRS can measure over 300,000 profiles a day. This new
data will yield considerable economic benefits through more accurate weather
forecasting and more reliable prediction of severe storm paths. AIRS will
also determine the effects of global warming on Earth's water cycle of evaporation
and rain and will demonstrate whether this cycle is accelerating, with implications
for floods, drought, and the management of fresh water resources.
