Version Summary

Sea ice extent and ice surface temperature algorithms and data sets are the same as Version 5. However, revisions and improvements for Version 6 to algorithm inputs have improved sea ice outputs as follows:

Revised calibration of MYD02 thermal bands 31 and 32 decreased calculated brightness temperatures by about -0.01 K and improved accuracy for very cold scenes;

The Version 6 land/water mask in the MYD03 geolocation product increased the accuracy of water body and coastline maps;

Revisions to the MYD35_L2 cloud mask algorithm have increased the accuracy of cloud detection.

Overview

MODIS/Aqua Sea Ice Extent 5-Min L2 Swath 1km (MYD29) data set contains 1 km resolution sea ice extent, ice surface temperature, and quality assessment data, plus 5 km resolution geolocation data. As of August 2023, this data set is retired and no longer available for download. We recommend using MODIS/Aqua Sea Ice Extent 5-Min L2 Swath 1km, Version 61 as an alternative.

General Questions & FAQs

Can I merge different MODIS collections?

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.

Missing and delayed MODIS data

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.
