Order Data

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).


AMSR/ADEOS-II data are restricted to NASA-approved designated users—defined by NASA as those who intend to use the data for research, application, education, or non-commercial/operational purposes for the public benefit. These data are therefore only available upon registration and in accordance with the AMSR/ADEOS-II Data Use Agreement.


First-Time Users   NASA-Approved Users
First-time users of AMSR/ADEOS-II data must complete a Registration Form and must also meet the criteria outlined by NASA to be approved as a designated user of these data. Upon receipt of your completed registration form, NSIDC will relay your information to NASA for processing. As soon as NSIDC is notified you are a NASA-approved designated user, we will contact you with instructions for accessing the data.   NASA-approved users of AMSR/ADEOS-II data may order the data using Reverb. Designed to work with ECHO, the Earth Observing System (EOS) Clearinghouse, Reverb also offers functions such as parameter and spatial subsetting.


Note: Unlike AMSR/ADEOS-II data, AMSR-E/Aqua data are not restricted and are available via the the AMSR-E/Aqua Data Web site. AMSR-E/Aqua refers to the Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) sensor on the NASA Aqua satellite.
