Data coverage
This data set contains daily 'cloud-free' snow cover produced from the VIIRS/JPSS-1 Snow Cover Daily L3 Global 375m SIN Grid, Version 2 snow cover product. A cloud-gap-filled algorithm is utilized to replace ‘cloud-covered’ pixels with ‘cloud-free pixels’ for the purpose of estimating the snow cover that may exist under current cloud cover. The data are provided daily and mapped to a 375 m sinusoidal grid. VJ110 This data set reports the location of snow cover using radiance data acquired by the Visible Infrared Imager Radiometer Suite (VIIRS) on board the Joint Polar Satellite System's first satellite (JPSS-1). Snow cover is identified using the Normalized Difference Snow Index (NDSI) and a series of quality control screens. VJ110D1F VJ110D1F is a daily global view of cloud-gap-filled (CGF) snow cover at 375 m resolution. This daily global product is produced by reprojecting all of the VJ110A1F product tiles from each day to a global geographic projection. The data files include the NDSISnowCover and CloudPersistence data layers from VJ110A1F . VJ110A1 This data set contains daily snow cover derived from radiance data acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) on board the Joint Polar Satellite System's first satellite (JPSS-1). The data is a gridded composite, generated from 6 minute swaths, and projected to a 375 m Sinusoidal grid. Snow cover is identified using the Normalized Difference Snow Index (NDSI) and a series of screens designed to alleviate errors and flag uncertain snow cover detections. VJ210D1F VJ210D1F is a daily global view of snow cover at 375 m resolution. This daily global product is produced by reprojecting the all the VJ110A1 product tiles for a day to a global geographic projection. Only the NDSISnowCover data layer from the VJ110A1 product is input to produce this global product. VNP10A1F This data set contains daily 'cloud-free' snow cover produced from the VIIRS/NPP Snow Cover Daily L3 Global 375m SIN Grid, Version 2 snow cover product. A cloud-gap-filled algorithm is utilized to replace ‘cloud-covered’ pixels with ‘cloud-free pixels’ for the purpose of estimating the snow cover that may exist under current cloud cover. The data are provided daily and mapped to a 375 m sinusoidal grid. VNP10 This data set reports snow cover using radiance data acquired by the Visible Infrared Imager Radiometer Suite (VIIRS) on board the Suomi National Polar-orbiting Partnership (NPP) satellite. Snow cover is identified using the Normalized Difference Snow Index (NDSI) and a series of quality control screens. VNP10D1F VNP10D1F is a daily global view of cloud-gap-filled (CGF) snow cover at 375 m resolution. This daily global product is produced by reprojecting all of the VNP10A1F product tiles from each day to a global geographic projection. The data files include the NDSISnowCover and CloudPersistence data layers from VNP10A1F . VNP10A1 This data set contains daily snow cover derived from radiance data acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) on board the Suomi National Polar-orbiting Partnership (NPP) satellite. The data is a gridded composite, generated from 6 minute swaths, and projected to a 375 m Sinusoidal grid. Snow cover is identified using the Normalized Difference Snow Index (NDSI) and a series of screens designed to alleviate errors and flag uncertain snow cover detections.
