dry land is warm (red).)
The Advanced Microwave Sounding Unit (AMSU-A) is a 15-channel microwave sounder for temperature profiling. The data will be used to profile the atmosphere in general and especially the stratosphere.
AMSU-A provides atmospheric temperature measurements from the surface up to 40 km. The temperature and water vapor data are used for worldwide civilian and military weather forecasting.
AMSU-A senses microwave radiation at 15 channels ranging from 15 to 90 GHz. The instrument scans a swath 1650 km wide at the nominal altitude of 705 km.
The accuracy and reliability of microwave data gathered by the instrument will be confirmed by comparing the satellite data to independent data.
Once the data is collected from the satellites and processed, it is placed in a "public" computer file for immediate access by atmospheric scientists. It is also available as "Direct Downlink."
AMSU instruments also flew on the NOAA K/L/M series of satellites. On Aqua, AMSU is integrally coupled with the AIRS instrument.
AMSU-A instrument data is NOT contained on this CD-ROM.
