Please use [NOAA/CFSR_HARMONIZED](https://developers.google.com/earth-engine/datasets/catalog/NOAA_CFSR_HARMONIZED.md.txt) for consistent temperature units (Kelvin). The National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) was designed and executed as a global, high-resolution, coupled atmosphere-ocean-land surface-sea ice system to provide the best estimate of the state of these coupled domains over the 32-year period of record from January 1979 to March 2011. It has been extended as an operational real-time product. The data in Earth Engine are only present starting from December 13, 2018. Forecasts are initialized four times per day (0000, 0600, 1200, and 1800 UTC). We ingest only a subset of bands from files matching `cdas1.t??z.pgrbh**03|00**.grib2`, i.e. files of only 0-hour and 3-hour forecasts as the others are omitted. The forecast length is indicated by the 'forecast_hour' metadata field. Some images contain only a subset of bands. Using this dataset with both "00" and "03" forecast types will require you to cast the bands across the collection. ### Bands **Bands** Pixel size: 55660 meters (all bands) | Name | Units | Min | Max | Pixel Size | Description | |---|---|---|---|---|---| | `u-component_of_wind_hybrid` | m/s | -47.24\* | 44.33\* | 55660 meters | u-component of wind at Hybrid level for 00 and 03 forecast | | `v-component_of_wind_hybrid` | m/s | -45.45\* | 46.36\* | 55660 meters | v-component of wind at Hybrid level for 00 and 03 forecast | | `Albedo_surface_3_Hour_Average` | % | 0\* | 91.6\* | 55660 meters | Albedo 3 hour average at ground or water surface for 03 forecast | | `Canopy_water_evaporation_surface_3_Hour_Average` | W/m\^2 | 0\* | 746\* | 55660 meters | Canopy water evaporation 3 hour average at ground or water surface for 03 forecast | | `Categorical_Rain_surface` | | 0\* | 1\* | 55660 meters | Categorical Rain at ground or water surface for 00 and 03 forecast | | `Categorical_Rain_surface_3_Hour_Average` | | 0\* | 1\* | 55660 meters | Categorical Rain 3 hour average at ground or water surface for 03 forecast | | `Categorical_Freezing_Rain_surface_3_Hour_Average` | | 0\* | 1\* | 55660 meters | Categorical freezing rain 3 hour average at ground or water surface for 03 forecast | | `Categorical_Ice_Pellets_surface_3_Hour_Average` | | 0\* | 1\* | 55660 meters | Categorical ice pellets 3 hour average at ground or water surface for 03 forecast | | `Categorical_Snow_surface_3_Hour_Average` | | 0\* | 1\* | 55660 meters | Categorical snow 3 hour average at ground or water surface for 03 forecast | | `Clear_Sky_Downward_Long_Wave_Flux_surface_3_Hour_Average` | W/m\^2 | 56\* | 483\* | 55660 meters | Clear Sky Downward Long Wave Flux 3 hour average at ground or water surface for 03 forecast | | `Clear_Sky_Downward_Solar_Flux_surface_3_Hour_Average` | W/m\^2 | 0\* | 1142\* | 55660 meters | Clear Sky Downward Solar Flux 3 hour average at ground or water surface for 03 forecast | | `Clear_Sky_Upward_Long_Wave_Flux_surface_3_Hour_Average` | W/m\^2 | 78\* | 698\* | 55660 meters | Clear Sky Upward Long Wave Flux 3 hour average at ground or water surface for 03 forecast | | `Clear_Sky_Upward_Solar_Flux_atmosphere_top_3_Hour_Average` | W/m\^2 | 0\* | 767\* | 55660 meters | Clear Sky Upward Solar Flux 3 hour average at ground or water surface for 03 forecast | | `Clear_sky_UV-B_Downward_Solar_Flux_surface_3_Hour_Average` | W/m\^2 | 0\* | 24.77\* | 55660 meters | Clear Sky UV-B Downward Solar Flux 3 hour average at ground or water surface for 03 forecast | | `Cloud_water_entire_atmosphere_single_layer` | kg/m\^2 | 0\* | 19\* | 55660 meters | Cloud water at entire atmosphere layer for 00 and 03 forecast | | `Cloud_Work_Function_entire_atmosphere_single_layer_3_Hour_Average` | J/kg | 0\* | 5791\* | 55660 meters | Cloud work function 3 hour average at entire atmosphere layer for 03 forecast | | `Convective_available_potential_energy_surface` | J/kg | 0\* | 6069\* | 55660 meters | Convective available potential energy at ground or water surface for 00 and 03 forecast | | `Convective_available_potential_energy_pressure_difference_layer` | J/kg | 0\* | 5559\* | 55660 meters | Convective available potential energy at specified pressure difference from ground to level layer for 03 forecast | | `Convective_Precipitation_Rate_surface_3_Hour_Average` | kg/m\^2/s | 0\* | 0.002\* | 55660 meters | Convective precipitation rate 3 hour average at ground or water surface for 03 forecast | | `Convective_precipitation_surface_3_Hour_Accumulation` | kg/m\^2 | 0\* | 19.2\* | 55660 meters | Convective precipitation 3 hour average at ground or water surface for 03 forecast | | `Direct_Evaporation_from_Bare_Soil_surface_3_Hour_Average` | W/m\^2 | 0\* | 767\* | 55660 meters | Direct evaporation from bare soil surface 3 hour average at ground or water surface for 03 forecast | | `Downward_Long-Wave_Radp_Flux_surface` | W/m\^2 | 60\* | 530\* | 55660 meters | Downward Long-Wave Rad.
