The Convection And Moisture EXperiment (CAMEX) is a series of field
research investigations sponsored by the Earth Science Enterprise of
the National Aeronautics and Space Administration (NASA). The fourth
field campaign in the CAMEX series (CAMEX-4) ran from 16 August to 25
September, 2001 and was based out of Jacksonville Naval Air Station,
Florida. CAMEX-4 focused on the study of tropical cyclone (hurricane)
development, tracking, intensification, and landfalling impacts using
NASA-funded aircraft and surface remote sensing instrumentation.
The ER-2 Doppler radar (EDOP) 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 degree
ahead of nadir. The beam width of the antenna is 3 degree in the
vertical and horizontal directions which, for a 20 km altitude, yields
a nadir footprint a the surface of 1 km.
