Description

This data set (ATL11) provides time series of land-ice surface heights derived from the ICESat-2 ATL06 Land-ice Height product. It is intended primarily as an input for higher level gridded products, but can also be used on its own as a spatially organized product that allows easy access to height-change information derived from ICESat-2 observations.

Version Description

Calculated all crossovers (including near 88 S); Determined the center of the y_atc search from the median of unique pair center locations.
