Preferred term
ARMAR
Definition
- 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 acquired. Additional information available at "http://daac.gsfc.nasa.gov/CAMPAIGN_DOCS/TOGA/armar.html" (en)
