ATOVS Sounding Products
The Advanced TIROS Operational Vertical Sounder (ATOVS) consists of High Resolution Infrared Radiation Sounder (HIRS), the Advanced Microwave Sounding Unit-A (AMSU-A) and AMSU-B for retrieving temperature, humidity and ozone sounding in all weather conditions. The Microwave Humidity Sounder (MHS), developed by EUMETSAT, replaced AMSU-B on NOAA-18, NOAA-19, and the European MetOp satellites. Currently the ATOVS is generating products from the NOAA-18, NOAA-19, and MetOp-2 (NOAA-15 processing was terminated from operations in 2013.) This instrument package provides information on temperature and humidity profiles, total ozone, clouds and radiation on a global scale to the operational user community.
