CAMEX-4 ER-2 DOPpler radar (EDOP)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/camex4/edop/data101
The reprocessed ER-2 Doppler Radar (EDOP) data were collected during the fourth field campaign in the Convection And Moisture EXperiment (CAMEX) series, CAMEX-4.
Description
This field campaign took place from August to September 2001 based out of Jacksonville Naval Air Station in Florida, with the purpose of studying various aspects of tropical cyclones in the region. The EDOP dataset is an X-band (9.6 GHz) Doppler radar mounted in the nose of ER-2.
The instrument has two fixed antennas, one pointing at nadir and the second pointing approximately 33 degrees ahead of nadir. The beam width of the antenna is 3 degrees in the vertical and horizontal directions which, for a 20 km altitude, yields a nadir footprint at the surface of 1 km. The ER-2 ground speed is nominally 210 m/s and the integration period used by the data system is 0.5 second.

The transmit pulse is 0.5 second and the gate spacing is over sampled at 37.5 meter interval. Minimum detectable reflectivity is about -10 dBZ at an altitude of 15 km with a 0.375 meters range gate spacing. These data are available in netCDF-4 format from August 15, 2001 through September 26, 2001.
