ECV Products and Requirements for Surface Wind Speed and Direction

These products and requirements reflect the Implementation Plan 2016 (GCOS-200). GCOS is reviewing and will update the requirements until 2022. More information on: gcos.wmo.int.

Surface Wind Speed and Direction Speed of air at a known height above the surface which is to be specified in the metadata (m/s). Direction from which wind is blowing at a known height above the surface which is to be specified in the metadata (degree true) 3 hr 10km/NA 0.5m/s and mean quadratic statistics to 10% of the locally prevailing mean wind speed, for speed >20m/s 0.05m/s/ decade For stability: International Vector Winds Science Team Meeting (M.Bourassa)
