Convection and Moisture Experiment 4

Project Description
CAMEX-4 is focused on the study of tropical cyclone (hurricane)
development, tracking, intensification, and landfalling impacts using
NASA-funded aircraft and surface remote sensing instrumentation. The
primary aircraft used during CAMEX-4 are the NASA DC-8 and ER-2
research airborne platforms. These instrumented aircraft will fly
over, through, and around selected hurricanes as they approachlandfall
in the Caribbean, Gulf of Mexico, and along the east coast of the
United States. The NASA aircraft will investigate upper altitude
regions of the hurricane not normally sampled. Where possible,
measurements will be compared and validated with coincident
observations from the QuikSCAT, Terra, and Tropical Rainfall Measuring
Mission satellites. This study will yield high spatial and temporal
information of hurricane structure, dynamics, and motion. These data,
when analyzed within the context of more traditional aircraft,
satellite, and ground-based radar observations,should provide
additional insight to hurricane modelers and forecasters who
continually strive to improve hurricane predictions.More accurate
hurricane predictions at landfall will result in decreasing the size
of necessary coastal evacuations and increasing the warning time for
those areas.

While remote sensing of the hurricane environment is the primary
objective of CAMEX-4, there will also be separate flights to study
thunderstorm structure, precipitation systems, and atmospheric water
vapor profiles. This portion of CAMEX-4 is known as KAMP, Keys Area
Microphysics Project. The objective of the KAMPflights is to improve
quantitative precipitation estimates from passive and active microwave
