EUMETSAT Sentinel-3 Marine Altimetry Handbook online

by |

The Sentinel-3 Marine Altimetry Handbook is a user guide that summarises the key information needed to enable a general or specialist end user to get information about Level 1 (L1), Level 2 (L2), Level 2 processed (L2P) and Level 3 (L3) marine altimetry products. The handbook includes information on the components of the altimetry system – the SAR Radar ALtimeter (SRAL), MicroWave Radiometer (MWR) and Precise Orbit Determination (POD) module – the specifics of the measurements techniques used, details on the corrections applied and processing steps taken to derive geophysical variables. The capability of the altimetry system is discussed in the context of its complementarity with, and improvements on, other altimetry missions, with notes on existing limitations. A discussion of file formats, processing tools and data-access routes precedes a presentation of available support resources. Where the detail is not held in the handbook itself, the user is pointed to further (primarily web-based) resources. (eumetsat.int)
