The Suomi-NPP spacecraft went into safe mode on 8/3/21 while executing a planned re-enabling of the star trackers as part of the Star Catalog loads. All of the instruments, including VIIRS, were recovered on 8/4/2021, but the VIIRS science team has determined that the data from 8/3/21 through 9/13/21 need to be reprocessed. That reprocessing is currently in progress.
Data Set ID: 
VNP29

VIIRS/NPP Sea Ice Cover 6-Min L2 Swath 375 m, Version 1

This data set reports the location of sea ice cover derived from radiance data acquired by the Visible Infrared Imager Radiometer Suite (VIIRS). Following the approach used by MODIS, Sea Ice is detected using the Normalized Difference Snow Index. The VIIRS instrument flies onboard the Suomi National Polar-orbiting Partnership (NPP) satellite.

This is the most recent version of these data.

FAQ

What data subsetting, reformatting, and reprojection services are available for VIIRS data?
The following table describes the data subsetting, reformatting, and reprojection services that are currently available for VIIRS data via the NASA Earthdata Search tool. Short Name Title Parameter Subsetting Spatial Subsetting  *... read more
How does VIIRS snow and sea ice data compare to MODIS
Data products from VIIRS are created to be similar to MODIS data products to ensure the continuity needed for the development of snow and sea ice climate records beyond the life expectancy of MODIS. The temporal resolution and spatial extent are identical in MODIS and VIIRS. A benefit of VIIRS snow... read more
Missing and delayed VIIRS data
The lag time between observations and availability of VIIRS products is only a few days. Lag time may be extended due to satellite maneuvers and extra quality assurance required for the geolocation data after the maneuver. The... read more
