 This 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.

+General information on GSWP3 data from personal communication between Hyunjun Kim and Agnes Ducharne:
 - 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.
-- 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."
