Document - Algorithms Theoretical Baseline Document
28 Mar 2023CryoTEMPO-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.

22 Nov 2021CryoTempo-EOLIS-Product-Handbook
This CryoTEMPO Product Handbook describes the operational products, a point cloud product containing the elevations derived using a swath processing algorithm and a gridded product with elevations at regularly spaced points on a grid. The operational products provide analysis ready data to a wider community of scientists rather than individual altimetry experts.

1 Mar 2019CryoSat L2 Prototype Input & Output Definition Document
The CryoSat Instrument Processing Facility (IPF) processes LO SIRAL data to level 2. The Processing chains to process the LOdata to L1b are called the IPF 1. The processors which convert Llb data to Level 2 are called the IPF2. This document defines the main external data interfaces for the IPF2 activity.
