The Campaign
The WB-57 Middle Latitude Cirrus Experiment (MidCiX) was a NASA field investigation focused on analyzing the microphysical properties of cirrus clouds to enhance cloud property retrievals for satellite observations. MidCiX conducted one deployment over the south-central United States from April to May 2004. The NASA WB-57 aircraft was equipped with multiple in situ cloud probes to measure properties such as particle size distribution, mass, and habit. The aircraft flew near the Southern Great Plains (SGP) Atmospheric Radiation Measurement (ARM) central facility to gather correlative ground-based measurements. MidCiX was a collaborative effort with the Department of Energy (DoE) and was funded through NASA’s Radiation Sciences program.
