AVHRR Polar Atmospheric Motion Vectors Climate Data Record Release 2 - Metop-A and -B

Abstract:
Tropospheric satellite winds at all heights below the tropopause in the polar regions (latitudes higher than 45º), derived from the infrared channel of the Metop AVHRR instrument. This is the second release of the polar atmospheric motion vectors data record. Data are accessible from the EUMETSAT Data Centre. This uses the version 3.1.1 of the EUMETSAT operational algorithm and forecast from ERA-Interim reanalyses as auxiliary data. The data record includes products generated using IR images (channel 4) taken from the AVHRR/3 imager on-board Metop-A and Metop-B polar satellites. Polar AMVs are derived using 2 AVHRR orbits leading to one product every 100 minutes. Each product contains several wind vectors with their associated speed, direction, height, and several quality indicators. The dataset covers the period from 1 March 2007 until 31 December 2017 for Metop-A, and from 24 April 2013 until 31 December 2017 for Metop-B. The coverage boundaries are polar caps poleward of 45 degrees. The dataset is available in two formats: the EUMETSAT EPS native format and the BUFR format. See Related Products tab for Release 1. This is a Thematic Climate Data Record (TCDR) produced for the Copernicus Climate Change Service.
