    CryoTEMPO-EOLIS-Algorithm-Theoretical-Basis-Document

    This document contains the Algorithm Theoretical Basis for the ESA CryoTEMPO-EOLIS project. The ATBD describes the scientific background and principle of the algorithms, their expected or known accuracy and performance, the input and output data, as well as capabilities and limitations. The CryoTEMPO-EOLIS consists of two distinct products: 1) A point product containing elevation point measurements with an associated uncertainty 2) A gridded product containing a spatial interpolation of the point product onto a uniform grid of elevations and corresponding uncertainty. This product covers three main regions: Antarctic ice sheet, Greenland ice sheet and the glacier regions, as defined by IMBIE (The IMBIE Team, 2018; The IMBIE Team, 2020) and RGI 7.0 (RGI Consortium, 2017). The glacier regions include Iceland, Svalbard, Arctic Canada, Russian Arctic, Alaska, Southern Andes.
