The level-2 MODIS cloud product consists of cloud optical and physical parameters. These parameters are derived using remotely sensed infrared, visible and near infrared solar reflected radiances. MODIS infrared channel radiances are used to derive cloud top temperature, cloud top height, effective emissivity, cloud phase (ice vs. water, opaque vs. non-opaque), and cloud fraction under both daytime and nighttime conditions. MODIS visible radiances are used to derive cloud optical thickness and effective particle radius and cloud shadow effects. Near infrared solar reflected radiance provides additional information in the retrieval of cloud particle phase (ice vs. water, clouds vs. snow). The shortname for this level-2 MODIS cloud product is MYD06_L2. MYD06_L2 consists of parameters at a spatial resolution of either 1- km or 5-km (at nadir). Each MYD06_L2 product file covers a five-minute time interval. This means that for 5-km resolution parameters, the output grid is 270 pixels in width by 406 pixels in length.C6.1 changes for the cloud optical property retrievals are low-impact, and are limited primarilyto ancillary product usage, the Quality Assurance (QA), and handling of cloud top (CT) propertiesfill values; no updates to retrieval science are implemented.For more information about the MODIS Cloud product, visit the MODIS-Atmosphere site at:https://modis-atmos.gsfc.nasa.gov/products/cloudFor more details regarding dataset changes read the document at https://modis-atmos.gsfc.nasa.gov/documentation/collection-61
