On Wednesdays from 8:30 a.m. to 12:00 p.m. (USA Mountain Time), AMSR-E, Aquarius, IceBridge, ICESat/GLAS, MODIS, and NISE data are normally unavailable for ordering due to system maintenance. However, on the first Wednesday of each month, these data will be unavailable for ordering from 8:30 a.m. to 1:00 p.m. (USA Mountain Time).
MODIS snow and sea ice data are available from five sources: the Data Pool, via Subscription, Reverb, the MODIS Interactive Subsetting Tool (MIST), and via RSS Data Feed. The following table provides a link to each source and a brief description to help you decide which will best suit your needs. Version numbers indicate the highest quality data that are available.
|The Data Pool provides direct FTP access to NSIDC Earth Observing System (EOS) data, including Aqua and Terra snow and sea ice data sets.|
|Subscribe to have new MODIS data automatically sent via FTP to your local server or staged on NSIDC's FTP site when the data become available.|
|Search and discover the entire archive of MODIS data, as well as data from NSIDC and other Earth Observing System Data and Information System (EOSDIS) data centers. Designed to work with ECHO, the Earth Observing System (EOS) Clearing House, Reverb also offers functions such as parameter and spatial subsetting.|
|The MODIS Interactive Subsetting Tool (MIST) provides a 7 km by 7 km subset time series of certain Version 5 (V005) MODIS products over the Greenland Climate Network (GC-Net) and the International Arctic Systems for Observing the Atmosphere (IASOA) stations. MIST also provides limited online analysis capabilities that include generating time series and scatter plots. Data are provided in a text Comma Separated Value (CSV) file format, courtesy of the Oak Ridge National Laboratory Distributive Active Archive Center (ORNL DAAC).|
