The datasets generated to date by SST CCI are available from the Centre for Environmental Data Archival via the page www.neodc.rl.ac.uk. Possibly it is most useful to go to the dataset pages using the DOIs of the datasets:
For SSTs derived only from the Advanced Very High Resolution Radiometers:
For SSTs derived only from the Along-Track Scanning Radiometers:
(This points to V1.1 of the dataset.)
For a gap-filled, daily blend ("SST CCI analysis") of the above datasets (with good feature resolution):
To get data, you need to register just your e-mail address with the data centre. If you try to access data without logging in, you get a page that says "access to the dataset is restricted". This is misleading: there is no restriction on obtaining SST CCI data, you simply need to be logged in to the data centre.
If you want some of our data in the simplest possible form, head to our 'easy download' page. You can get the monthly SST time series for a particular latitude and longitude in a format readable into a spreadsheet.
