Overview

MODIS/Terra Sea Ice Extent Daily L3 Global 1km EASE-Grid Day (MOD29P1D) data set contains fields for Sea Ice by Reflectance, Sea Ice by Reflectance Spatial Quality Assessment (QA), Ice Surface Temperature (IST), and IST Spatial QA in Hierarchical Data Format-Earth Observing System (HDF-EOS) format, along with corresponding metadata. The fields Sea Ice by IST and Combined Sea Ice that were in Version 4 were removed from Version 5. MOD29P1D Version 5 (V005), the latest version of the Moderate Resolution Imaging Spectroradiometer (MODIS) data, consists of 954 x 954 km files of 1 km resolution data gridded in the Lambert Azimuth Equal Area map projection. The sea ice algorithm uses a Normalized Difference Snow Index (NDSI) modified for sea ice to distinguish sea ice from open ocean, based on reflective and thermal characteristics. MODIS/Terra V005 data extend from 24 February 2000 to present; however, until reprocessing is complete in mid-2008 not all V005 data will be available. The only data available for Version 4 (V004) is the Golden Month, which is a sample of V004 data covering the time period 29 August 2002 (day of year 241) through 7 October 2002 (day of year 280). The Golden Month is only available by special request by contacting NSIDC User Services. Please note that NSIDC now has a complete series of Version 5 data, which is the highest version number now available and represents the best quality of data.

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.

How do I access data using OPeNDAP?

OPeNDAP, the Open-source Project for a Network Data Access Protocol, is a NASA community standard DAP that provides a simple way for researchers to access and work with data over the internet.

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.
