Order Data

On Wednesdays from 9:00 a.m. to 12:00 p.m. (USA Mountain Time), AMSR-E, 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 9:00 a.m. to 1:00 p.m. (USA Mountain Time).

The MODIS snow and sea ice data are available from five data sources: the Data Pool, via Subscription, the Search 'N Order Web Interface (SNOWI), the Warehouse Inventory Search Tool (WIST), and the MODIS Interactive Subsetting Tool (MIST). The following table provides a link to each data source and also gives an explanation as to what each data source offers; thus, explaining why you may want to use one data source over another data source. The highest version number represents the best quality data available.

Data Source Link	Data Source Information
Data Pool	The Data Pool provides direct FTP access to the NSIDC EOS data. It offers users the HEG - HDF-EOS to GeoTIFF Conversion Tool, which allows users to reformat, re-project, and perform subsetting operations. However, this version of the HEG tool does not have all the features of the stand-alone HEG tool, which offers stitching/mosaicing.
Subscription	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.
SNOWI	The Search 'N Order Web Interface (SNOWI) can be used to access the entire archive of MODIS/Terra and MODIS/Aqua data. It is an easy interface to use. It allows a maximum of 1500 granules per order. Only searches NSIDC data. It does not offer subsetting.
WIST	The Warehouse Inventory Search Tool (WIST) can be used to access the entire archive of MODIS/Terra and MODIS/Aqua data, as well as data from a wide variety of other instruments and other Earth Observing System Data and Information System (EOSDIS) data centers as well as other data providers. The WIST allows for searching by parameter, spatial subsetting, and tile searching for select products. However, it only allows a maximum of 1000 granules per order, and it is a complex interface to use.
MIST	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).
