Version Summary
Version Summary
This C61 product is identical in format to the C6 version and the C61 reprocessing does not contain any change to the science algorithm used to generate this product. Any improvement or change in the C61 product compared to the C6 product is from changes and enhancements to the calibration approach used to generate the input products and changes to the polarization correction used in this collection reprocessing.
Overview
This global Level-3 (L3) data set provides daily nighttime ice surface temperature derived from the 'MODIS/Aqua Sea Ice Extent 5-Min L2 Swath 1km' (https://doi.org/10.5067/MODIS/MYD29.061) product. Each data granule is a tile consisting of 10 x 10 degrees of data gridded to the Lambert Azimuthal Equal Area Scalable Earth Grid (EASE-Grid).
The terms "Version 61" and "Collection 6.1" are used interchangeably in reference to this release of MODIS data.

General Questions & FAQs
For the snow cover and sea ice products, users can use MODIS Collections 6 and 6.1 together.
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 MODIS 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.
