This is the first release of the reprocessed Atmospheric Motion Vectors (AMV) Thematic Climate Data Record (TCDR) from the Advanced Very High Resolution Radiometer (AVHRR) in Global Area Coverage (GAC) resolution, from NOAA-15, 18 and 19 and Metop-A and B. AMV are derived only over both poles polewards of 40°. It contains AMV at all heights below the tropopause, derived from images in the Infrared channel at 10.8 microns. Vectors are retrieved by tracking the motion of clouds in two consecutive images. The height assignment of the AMVs is calculated using the Cross-Correlation Contribution (CCC) function to determine the height using the pixels that contribute the most to the vectors. A quality indicator is derived for each vector to assess the reliability of the retrieval. Products are stored in EPS Native format and cover the period from January 2014 to December 2018.
This is a Thematic Climate Data Record (TCDR).
