Cirrus cloud properties derived from satellite and coincident lidar data taken during the FIRE IFOCloud-top temperatures are derived from lidar measurements taken during the First ISCCP Regional Experiment Cirrus Intensive Field Observation program in October-November, 1986. The results are used to estimate cloud emissivities from satellite-measured IR radiances. The relationship beween IR emissivity and the observed visible reflectances for various solar zenith and satellite zenith angles. The results support the model of flux emissivity vs cloud albedo which is used in the ISCCP cloud property retrieval algorithm. Also, the results show that scattering is more isotropic than previous studies have suggested.
