SMART uses two separte spectrometer to cover the solar spectral range. To overcome differences in the timing of both components, a running mean (5 sec) was applied to the reflectivity time series in the retrieval algorithm. Therefore, cloud optical thickness, cloud particle size and snow grain size...

Description
Summary:SMART uses two separte spectrometer to cover the solar spectral range. To overcome differences in the timing of both components, a running mean (5 sec) was applied to the reflectivity time series in the retrieval algorithm. Therefore, cloud optical thickness, cloud particle size and snow grain size are smoothed as well while the reflectivity time series are provided as raw data without running mean.MODIS cloud products were selected and averaged for an area of 5x5 pixel with the aircraft observations centered in this area.tau_MODIS: MODIS cloud product Collection 6: Cloud Optical Thickness (dimensionless) two-channel retrieval using band 7(2.1 µm) and band 6(1.6 µm) from best points: not failed in any way, not marked for clear sky restoraltau_MODIS_16: MODIS cloud product Collection 6: Cloud Optical Thickness (dimensionless) two-channel retrieval using band 7(2.1 µm) and either band 1(0.65 µm) , 2(0.86 µm) , or 5(1.2 µm) (specified in Quality_Assurance_1km) from best points: not failed in any way, not marked ...
