    202202The Princeton forcing uses CRU data for bias-correction, but the present forcing includes an additional bias-correction of total precipitation, based on the monthly GPCC data. This has been performed by Bertrand Decharme (CNRM, Toulouse). 
    203203 
    204 === 1.7 ERA_05 === 
    205  
    206 This meteorological data set has been prepared by ECMWF in the framework of the Earth2Observe project : http://www.earth2observe.eu/ 
    207  
    208 Using a simple bi-linear interpolation the data of the ERA-I re-analysis on the Gaussian grid (N128) output was projected to a regular lat/lon grid at 0.5deg resolution, without special consideration for the land/sea mask. It was thus considered, in consultation with Emanuel Dutra of ECMWF, that it was not unreasonable to use the same land/sea mask as WFDEI and hope that the atmospheric forcing on coastal points will not be too badly affected by the methodology. 
    209  
    210 The value of this forcing lies in its close relation to the ERA-I re-analysis and its extension to December 2014.

    217 === 1.8 ERA_05_GPCP

    219 This is the same forcing as ERA_05 except for the rainfall and snow fall from the re-analysis which were corrected with the GPCP estimates (http://precip.gsfc.nasa.gov/).

     204=== 1.7 GSWP3  
    226205 
    227206This forcing has been constructed for the GSWP3 experiment, cf. http://hydro.iis.u-tokyo.ac.jp/GSWP3/exp1.html#boundary-conditions. It is based on the 20th Century Reanalysis (20CR) [Compo et al., 2011 http://hydro.iis.u-tokyo.ac.jp/GSWP3/refs.html#compo2011] at the global 2° resolution, dynamically downscaled into T248 (~0.5°). Several versions are available.

    230209- All variable treated in the same way in terms of time averaging. First time record should corresponds to 00UTC, but please note values represents "backward averaging" which means 00UTC is mean of -03 ~ 00UTC. 
    231210- Wind should be assumed to represent speed at 10 m. Downscaled reanalysis wind speed is at 10m, but CRU CL2.0 data which is used to correct long-term mean has not been corrected for any measurement height related issue. New et al. (2002) says "Wind speed is measured at heights above the surface of between 2 and 20 m. Measurement height varies both within and between countries, and in many cases the heights were not specified. Consequently, no corrections were made to wind data. The large majority of known heights were 10 m, and the interpolated wind field should be assumed to represent speed at this height."

    252 This dataset was build in the framework of the Earth2Observe FP7 project. It is available on the IPSL Meso-centre under /bdd/ORCHIDEE_Forcing/BC/OOL/OL2/E2OFD. It was prepared by Jan Polcher based on the data prepared by ECMWF for the Earth2Observe project. 
    253  
    254 The originality of this forcing is that it is 1/4°. Most atmospheric forcing data sets were extrapolated from the ERA-I fields with the same bias corrections applied as in the WFDEI cases. The most original feature is the rainfall which is the very original MSWEP product : https://www.hydrol-earth-syst-sci.net/21/589/2017/
