ECV Products and Requirements for Surface Radiation Budget
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 | FREQ. | RES. | REQUIRED MEASUREMENT UNCERTAINTY | STABILITY | STANDARDS/ REFERENCES |
| Surface ERB longwave | Flux density of radiation emitted by the gases, aerosols and clouds of the atmosphere to the Earth's surface (W/m2) | Monthly (resolving diurnal cycle) | 100km/NA | Requirements on global mean: 1W/m2 | 0.2W/ m2 / decade | |
| Surface ERB shortwave | Flux density of the solar radiation at the Earth's surface (W/m2) | Monthly (resolving diurnal cycle) | 100km/NA | Requirements on global mean: 1W/m2 | 0.2W/ m2 / decade |
