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 Aerosonde is an unmanned aerial vehicle with a wingspan of a 2.9
meters (~9 feet) weighing approximately 14 Kg (~31 lbs). Carrying a
payload of air pressure, temperature and humidity probes, the aircraft
can fly at altitudes from near the surface to 21,000 feet at speeds of
50-95 mph for periods of up to 30 hours. Controlled by dual computers
and navigated by GPS, the Aerosonde is designed to economically
collect meteorological data over a wide area.
