Along flow acceleration of the Greenland ice sheet

The acceleration of Greenland ice flow derived from ITS_LIVE annual velocity data spanning 1985-2018.

There are two variations of using either weighted and unweighted least squares in the estimation. The data files follow the format:

weighted--ax.tif | acceleration in the x direction:

weighted--ay.tif  | acceleration in the y-direction.

weighted--a.tif | acceleration in the dominant flow direction

weighted--asigma.tif | standard error estimate of the "weighted--a" data.

weighted--N.tif | Number of years with data for each grid point.

All data are using a polar stereographic projection (EPSG:3413). 

This dataset was created as part of the study: Grinsted et al. 2022, Accelerating ice flow at the onset of the Northeast Greenland ice stream. Processing choices is detailed there.
