Abstract
The Intensive Field Observation of E1TCREX 94. (EUropean Cloud and Radiation EXperiment) held in April 1994 in Brest, France. was a three-aircraft and ground-based experiment dedicated to the development and the validation of algorithms to derive relations between cirrus radiative properties and cirrus microstructure from remote sensing measurements. A niultiangular visible radiometer with polarization capabilities called 1OLDER (POLarization and Directionality of Earth Reflectances) was installed doviiward. on-board the instrumented German Falcon of the DLR. This aircraft was also equipped with upwar(l and downward pyra.nometers and pyrgeometers and with PMS probe. The second instrumented aircraft was the ARAT (French Fokker 27 of INSU). It was equipped with the upward lidar LEANDRE (\ = O.53jtm), with a photometer POLDER looking downward, an(1 with upward and downward infrared radiometers (;\ E [9.5gm - 11.5um]) and upward and downward pyraliometers and pyrgeometers. During the upward and downward observations of the Fokker under cirrus, the Falcon performed optical measurements above and microphysical measurements i uside clouds. A ground-based station with Lidar, infrared radiometric and sunphol.omet.er measurenients w'as also operating during the same time. The third aircraft was specially devoted to the low level clouds and was equipped with a Fast FSSP, upward and downw'ard pyia noiieters and pvrgeometers and upward and downward infrared radiometers. During this intensive field of observations. four well documented cirrus cases were observed from aircraft and from the ground. Ana1ve of these observations is I)resented by comparison to a radiative transfer calculations. These calculations are performed taking into account the optical properties of hexagonal ice crystals obtained by a. ray-tracing method. All theses observations allow to determine a. bulk Properties of cirrus clouds in particular a. ra.dia.t.ively equivalent microstructure.
