Abstract

The Advanced Microwave Precipitation Radiometer is an across-track scanning, four channel, total power radiometer system specifically designed to mount and operate within the NASA ER-2 aircraft. Nadir resolutions on the Earth's surface are 2.8 km at 10.7 and 19.35 GHz, 1.5 km at 37.1 GHz, and 640 meters at 85.5 GHz. A stepper motor spins an offset reflector ±45° across-track and directs upwelling scene emission towards lens/feedhorn assemblies. The scan rate is sufficient to provide contiguous mapping at 85.5 GHz, with spatial oversampling occurring for the three lower frequencies. For an ER-2 flight altitude of 20 km, the total acrosstrack swath width on Earth is ≈ 40 km. On 12 August 1991 during the Convection and Precipitation/Electrification (CaPE) experiment, measurements were gathered with the AMPR and the National Center for Atmospheric Research (NCAR) CP-2 dual-polarization radar system.
