Jan 25, 2011 · The 20th Century Reanalysis Project, outlined in the Quarterly Journal of the Royal Meteorological Society, not only allows researchers to understand the long-term impact of extreme weather, but provides key historical comparisons for our own changing climate.Recent land surface air temperature trends assessed using 20cr advancing reanalysisOct 27, 2011 · This is done using the 20th Century Reanalysis (20CR [Compo et al., 2006, 2011]). 20CR covers 18712008 and is driven only by observed sea surface temperatures and sea ice [Rayner et al., 2003], atmospheric CO 2 concentrations, solar and volcanic forcings, and observations of surface pressure over both land and ocean. No land surface changes 20cr advancing reanalysisReanalysis Datasets at PSL: NOAA Physical Sciences Laboratory20th Century Reanalysis (V3, V2C, and V2) (1836-2015) PSL began the 20th Century Reanalysis project in 2009. The project was based on the research results suggesting that using just surface pressure observations together with sea/ice boundary conditions as inputs to a climate model produces reasonable results up to the tropopause.
