Preliminary AMSR-E/Aqua Level-2 and Level-3 data are available via FTP. The most recent eight days of data are made available to researchers as quickly as possible after production. For example, beginning 01 March, data from 21 to 28 February are available via FTP. On 02 March, data from 22 to 29 February are available, and data from 21 February are deleted from the FTP site because the official, more complete data are now available through the Data Pool and Warehouse Inventory Search Tool (WIST).
Preliminary data access is unrestricted, but we ask that you register by filling out the form in the link below. NSIDC User Services will e-mail you as soon as possible with a user name and password to access the data via FTP.
