V1 was initially completed as a test from 1950-1958. V2 covers the period from 1871-2012 . The model used is a 2008 experimental, reduced-resolution version of the NCEP Global Forecast System (GFS2008ex). Briefly, that model has a spatial resolution of nearly 200-km on an irregular Gaussian grid in the horizontal (corresponding to a spherical harmonic representation of model fields truncated at total wavenumber 62, T62). In the vertical, we use finite differencing of 28 levels. The model has a complete suite of physical parameterizations as described in Kanamitsu et al. (1991) with updates detailed in Moorthi et al. (2001). Additional updates to these parameterizations are described in Saha et al. [Need YEAR] and include revised solar radiation transfer, boundary layer vertical diffusion, cumulus convection, and gravity wave drag parameterizations. In addition, the cloud liquid water is a prognostic quantity with a simple cloud microphysics parameterization. The radiation interacts with a fractional cloud cover that is diagnostically determined by the predicted cloud liquid water. The radiation also interacts with stratospheric ozone that is determined prognostically. The GFS2008ex also includes the radiative effects of historical time-varying CO2 concentrations, volcanic aerosol and solar variations using the longwave radiation model of Mlawer et al. (1997) and shortwave radiation model of Hou et al. (2002). Pressure observations are from the International Surface Pressure Databank station component version 3. It is run as an 56 member forecast ensemble. The boundary forcing is taken from the Soda C (time-evolving sea-surface temperature and sea-ice). The model is run using 9 hour integrations of the ensemble members. A subset of the model variables are output every 6 hours. Additional variables are available every 3 hours. In addition to the subdaily values, the dataset also includes daily and monthly average values. In addition to the mean values, standard deviations of the 56 ensemble members are also provided for the subdaily and monthly average output. Subdaily, daily, and monthly long terms means of both the model means and standard deviations are also provided (1981-2010). Output includes 2D and 3D variables. The 3D atmospheric variables are on 24 pressure levels extending from 1000mb to 10mb. Soil moisture is provided on 4 levels. The horizontal resolution of the 2D and 3D variables are about 2 degrees latitude by 2 degrees longitude. Individual ensemble members are available via the <a href="https://portal.nersc.gov/project/20C_Reanalysis/. ">NERSC interface</a>. All data are in netCDF4 format. Total 20CRV2 data volume at PSL is approximately 4TB. In general, data is divided into annual files (except for monthly values). The files are available via FTP and OPEnDAP (THREDDS) and a selection of plotting and analysis tools. ongoing https://psl.noaa.gov/data/gridded/images/small/twentcv2.png 6-hourly Relative Humidity Spread at sigma level 0.995 6-hourly Air Temperature Spread at sigma level 0.995 6-hourly Pressure Spread at Tropopause 6-hourly CAPE Spread 6-hourly CIN Spread 6-hourly V-wind Spread at sigma level 0.995 6-hourly Pressure Spread at Mean Sea Level 6-hourly Precipitable Water Spread for entire atmosphere 6-hourly V-wind Spread at Tropopause 6-hourly Potential Temperature Spread at sigma level 0.995 6-hourly Cloud Water Spread for entire atmosphere 6-hourly Pressure Spread at Surface 6-hourly Omega Spread at sigma level 0.995 6-hourly U-wind Spread at sigma level 0.995 6-hourly U-wind Spread at Tropopause 6-hourly Geopotential Heights Spread at Tropopause 6-hourly Total Columnar Ozone Spread 6-hourly Air Temperature Spread at Tropopause 6-hourly Relative Humidity Spread on Pressure Levels 6-hourly U-wind Spread on Pressure Levels 6-hourly Air Temperature Spread on Pressure Levels 6-hourly Omega Spread on Pressure Levels 6-hourly Geopotential Heights Spread on Pressure Levels 6-hourly V-wind Spread on Pressure Levels 6-hourly Specific Humidity Spread on Pressure Levels 3-hourly Liquid Volumetric Soil Moisture (non-frozen) Fraction 3-hourly Soil Temperature 3-hourly Soil Moisture Content 3-hourly Ice Thickness at Surface 3-hourly Total Cloud Cover 3-hourly Momentum Flux, u-component at surface 3-hourly Height of Pressure Boundary Layer 3-hourly Potential Evaporation Rate at surface 3-hourly Albedo at Surface 3-hourly Pressure at surface 3-hourly Specific Humidity at 2 m 3-hourly UV-B Downward Solar Flux 3-hourly Air Temperature at 2 m 3-hourly Maximum Temperature at 2 m 3-hourly U-wind 3-hourly Top Cloud Cover 3-hourly Upward Longwave Radiation Flux at nominal top of atmosphere 3-hourly Exchange Coefficient 3-hourly Meridional Gravity Wave Stress at surface 3-hourly Water Runoff at surface 3-hourly Precipitable Water for entire atmosphere 3-hourly Cloud Work Function 3-hourly Canopy Water Evaporation 3-hourly Middle Cloud Cover 3-hourly Ground Heat Flux at surface 3-hourly V wind 3-hourly Boundary Layer Cloud Cover 3-hourly Ice Concentration at surface 3-hourly Plant Canopy Surface Water 3-hourly Low Cloud Cover 3-hourly Water Equiv. of Accum.
