Optical Thickness Cross-Calib. (FIFE)

The objective of the Optical Thickness Calibration study was to compare aerosol optical thickness measurements derived from three different groups. These groups measured atmospheric transmission, in particular, the aerosol optical thickness, using at least three different instruments (e.g., a solar transmissometer SXM-2, a Reagan sunphotometer, and an airborne tracking sunphotometer) and three different analysis procedures.
