OCA Atmospheric Motion Vectors Climate Data Record Release 1 - MSG - 0 degree

Release 1 of the Climate Data Record (CDR) of MSG imager SEVIRI (Spinning Enhanced Visible Infra-Red Imager) Atmospheric Motion Vectors (AMV) located at the 0° position. This release covers the MSG SEVIRI record from four different satellite platforms Meteosat-8 to -11. The CDR covers 15 years from 19 January 2004 until 31 August 2019 and there is a hourly products in netCDF format. It provides information on AMV speed (ms-1), direction (degree), and height (given in pressure units Pa) of vectors which are derived by tracking cloud or water vapour features between two images in time. The vectors height is derived using the OCA cloud properties (DOI:[10.15770/EUM_SEC_CLM_0049](https://doi.org/10.15770/EUM_SEC_CLM_0049)). AMV are wind vectors retrieved at all heights below the tropopause, derived from the following channels: - Visible 0.6 microns - Water Vapour 6.2 microns and 7.3 microns - Infrared 10.8 microns The data record has been generated using the standalone version of the operational software used for SEVIRI in the EUMETSAT operational Level 2 Meteosat Product Extraction Facility (MPEF) and it is fully described in (MSG Meteorological Products Extraction Facility Algorithm Specification Document - EUM/MSG/SPE/022 v7B).
