Sounding data provides:

§ 3-D temperature and moisture profiles § Rainfall rates § Snow/ice information

Advanced Technology Microwave Sounder (ATMS)

Higher resolution—Wider swath—Much smaller gaps between passes

Resolution: ATMS vs. AMSU

Sounding data improves:

§ Short- and medium-term forecasting § Storm tracking

Rainfall rates during Hurricane Sandy

ATMS and our legacy microwave sounders provides critical data for weather forecasting. The microwave products are used for many nowcasting, hydrological and climate applications including: Hurricane intensity Rainfall rates Snowfall rates and snow water equivalent Snow and Ice monitoring Long-term records of atmospheric temperature and water vapor.
