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.
| PRODUCT | DEFINITION | FREQUENCY | RESOLUTION | REQUIRED MEASUREMENT UNCERTAINTY | STABILITY | STANDARDS/ REFERENCES |
| 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) |
