All SNPP VIIRS forward processing has been temporarily suspended due to a GPS anomaly issue that began at 231Z November 2, 2024. All production of SNPP VIIRS land data products are suspended and until further notice users are advised not to use any SNPP VIIRS data products produced since 215Z on November 2, 2024. The NASA NSIDC DAAC will post updates as they become available.

General Questions & FAQs
The answer is yes! There are several ways to programmatically access NSIDC data products and metadata using Application Programming Interfaces (APIs). We also provide the ability to access data using an FTP client.
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.
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 following table lists the tools and services available for VIIRS data.
This short article describes the customization services available for VIIRS data using Earthdata Search.
