ARMAR was developed by NASA/JPL for the purpose of supporting future
spaceborne rain radar systems, including the radar for the Tropical
Rain Measuring Mission (TRMM) which was flown in November 1997. It
flies on the NASA Ames DC-8 aircraft and is operated by JPL. Its
primary goal in TOGA COARE was to measure the three-dimensional
reflectivity of rainfall.

Instrument Geometry:

ARMAR operates with the TRMM frequency and
geometry, measuring reflectivity at 13.8 GHz in a cross-track scan
+/-20 degrees from nadir along the flight track of the
aircraft. Nadir-looking, non-scanning measurements can also be
