Data format: 

Gridded data given in columns as below:

Longitude
Latitude
Height (always 0)
Sea level anomaly (SLA)

The filename states the region (Arctic) and the month and year of the dataset (YYYYMM).

The dataset has been obtained using satellite altimetry data from four missions:
ERS1, ERS2, Envisat, CryoSat-2 

Spatial coverage: 66N-82N with a resolution of 0.25*0.5 degrees (lat: 66:0.5:82 and lon: -180:0.5:180)

Data points retrieved over land have been removed from files in the folder “Masked”, where filenames end with “ocean”.
