-The Sea Ice Surface Temperature (Day) layer shows the "skin" temperature of the sea ice surface measured in Kelvin (K). It is derived from radiance data acquired by the Visible Infrared Imager Radiometer Suite (VIIRS) aboard the joint NASA/NOAA Joint Polar Satellite System's first satellite (JPSS-1/NOAA-20). Following the approach used by MODIS, the algorithm converts VIIRS calibrated radiances into brightness temperature and computes Ice Surface Temperature (IST) using a split-window technique. Sea Ice Surface Temperature (IST) is an indicator of freeze/thaw processes on ice and has been used to separate thin ice from open water.

+The VJ121 product is developed synergistically with the Moderate Resolution Imaging Spectroradiometer (MODIS) LST&E Version 6.1 product (MOD21) using the same input atmospheric products and algorithmic approach based on the ASTER Temperature Emissivity Separation (TES) technique. The VJ121 product uses a physics-based algorithm to dynamically retrieve both the LST and emissivity simultaneously for VIIRS thermal infrared bands M14 (8.55 µm), M15 (10.76 µm), and M16 (12 µm). The TES algorithm is combined with an improved Water Vapor Scaling (WVS) atmospheric correction scheme to stabilize the retrieval during very warm and humid conditions. The overall objective for NASA VIIRS products is to ensure the algorithms and products are compatible with the MODIS Terra and Aqua algorithms to promote the continuity of the Earth Observation System (EOS) mission.

+The Snow Cover (Normalized Difference Snow Index (NDSI)) layer shows an estimate of snow cover. It is derived from radiance data acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the Joint Polar Satellite System's first satellite (JPSS-1/NOAA-20). Snow-covered land typically has very high reflectance in visible bands and very low reflectance in the shortwave infrared bands. The Normalized Difference Snow Index (NDSI) reveals the magnitude of this difference, with values greater than 0 typically indicating the presence of at least some snow. The VIIRS snow cover algorithm computes NDSI using VIIRS image bands I1 (0.64 µm, visible red) and I3 (1.61 µm, shortwave near-infrared) and then applies a series of data screens designed to alleviate
+likely errors and flag uncertain snow detections.
