In addition to the EDR imagery products, the VIIRS product suite contains a wide variety of geophysical products (i.e., EDRs), include those for atmosphere (e.g., aerosol optical thickness, AOT; aerosol detection products, ADP), land (e.g., variety of vegetation indices, VI; green vegetation fraction, GVF; land surface temperature, LST), ocean (e.g., sea surface temperature, SST; ocean color, OC), and cryosphere (e.g., ice surface temperature, IST; sea ice thickness, concentration; snow fraction, polar winds). Many of these products use the enterprise VIIRS cloud mask (ECM), which is based on heritage from the Advanced Very High Resolution Radiometer (AVHRR) Pathfinder Atmospheres Extended (PATMOS-x) and naive Bayesian approach [37; 38]. The ECM has been applied to multiple sensors (e.g., AVHRR, Geostationary Operational Environment Satellite, GOES-16 Advanced Baseline Imager, ABI), and the cloud products have been tested against the Cloud-Aerosol LiDAR and Infrared Pathfinder Satellite Observation (CALIPSO) and MODIS cloud mask (MYD25) products [39; 40]. The primary output from the ECM is cloud probability, along with a 4-level cloud mask derived solely from the cloud probability. In addition, the enterprise cloud algorithm uses a set of seven algorithms to produce a full suite of cloud products, such as cloud phase/type, cloud top/base height, cloud top temperature, cloud top pressure, cloud optical depths, particle sizes, and cloud water path. The VIIRS ECM cloud products are provided to NWS Aviation Weather Center for global monitoring of aviation hazards [41]. NOAA OAR uses the cloud-product information for model verification over Polar Regions, and cloud height information is used in deriving polar atmospheric motion vectors [42; 43]. The ECM and cloud height are used in resolving some of the artifacts in the CrIS clear radiance for NWP data assimilations [42; 44]. Figure 3 shows an example of the VIIRS daytime cloud-mask derived from the NOAA enterprise cloud product algorithm. The enterprise cloud products performances are provided in Tables 2-4.
