CRYSTAL-FACE, Cirrus Regional Study of Tropical Anvils and Cirrus Layers-Florida Area Cirrus Experiment, was a measurement campaign designed to investigate tropical cirrus cloud physical properties and formation processes. Understanding the production of upper tropospheric cirrus clouds is essential for the successful modeling of the Earth's climate. The CRYSTAL-FACE mission took place during the month of July 2002 in the south Florida region. Measurements from ground sites, aircraft, and satellites were conducted, and the vast majority of aircraft flights were coordinated with NASA's Terra, Aqua, and/or TRMM satellites.
