On Wednesday, January 18 from 9:00 a.m. to 11:00 a.m. (USA Mountain Time) AMSR-E, Aquarius, IceBridge, ICESat/GLAS, MODIS, NISE, and SMAP data will not be available for ordering due to system maintenance.

Access to data via FTP for this data set will no longer be available after January 31, 2017. The NASA NSIDC DAAC is transitioning to data distribution through HTTPS, which requires users to login with an Earthdata Login username and password. Data will continue to be available free of charge.

DOWNLOADING DATA VIA FTP

Data can be downloaded through a Web browser or command line via FTP. When using a Web browser, the FTP link first directs you to an Optional Registration Form that if filled out, will allow you to receive notifications about updates or processing changes related to that specific data set. After completing the Optional Registration Form, the FTP directory becomes available. For additional help downloading data through an FTP client, go to the How to access data using an FTP client support page.

AE_Ocean

AMSR-E/Aqua L2B Global Swath Ocean Products derived from Wentz Algorithm, Version 2

The Level-3 daily product (AE_DyOcn), weekly product (AE_WkOcn), and monthly product (AE_MoOcn) include SST, near-surface wind speed, columnar water vapor, and columnar cloud liquid water over oceans in a 0.25 degree by 0.25 degree grid, generated from AE_Ocean.

FAQ

Why does the number of pixels per scan vary among different Level-2 AMSR-E data sets?

A typical AMSR-E swath width consists of approximately 2000 scans, with 243 pixels per scan for the 6.9 GHz to 36.5 GHz channels, and 486 pixels per scan for the 89.0 GHz channel.

In 2002, the AMSR-E science team discovered distortion along the outer 23 to 24 pixels of each swath. Some... read more
