The advanced microwave sounding unit
The advanced microwave sounding unit (AMSU) is a multi-channel microwave radiometer installed on meteorological satellites. The instrument examines several bands of microwave radiation from the atmosphere to perform atmospheric sounding of temperature and moisture levels. See more Level-1 radiance data are calibrated brightness temperatures. Level-2 geophysical data from AMSU include: • Temperature profile from 3 mbar (45 km) to the surface See more AMSU data is used extensively in weather prediction. Brightness temperatures are processed as quickly as possible and sent to numerical weather prediction (NWP) centers around the world. This data helps keep the assessment of the current state of the atmosphere … See more The AMSU has two sub-instruments, AMSU-A and AMSU-B. AMSU-A has 15 channels between 23.8 and 89 GHz, and is used primarily for measuring atmospheric temperatures (known as "temperature sounding"). It has a ground resolution near nadir of 45 km. … See more AMSU-A + AMSU-B have flown together on the 3 NOAA KLM satellites: NOAA-15 (NOAA K), launched May 13, 1998; NOAA-16 (NOAA … See more AMSUs are always situated on polar-orbiting satellites in sun-synchronous orbits. This results in their crossing the equator at the same two local solar times every orbit. For example, EOS Aqua crosses the equator in daylight heading north (ascending) at … See more • Data processing for AMSU at Colorado State • AMSU-A datasheet from NASA's EOS Aqua project • NOAA KLM User's guide AMSU-A See more WebAMSU-B is a 5 channel microwave radiometer (89.0, 150.0, ...
