Description:"The NMC/NCAR Reanalysis Project began in 1991 as an outgrowth of the NMC Climate Data Assimilation System (CDAS) project. The motivation for the CDAS was the fact that the many changes introduced in the Global Data Assimilation System (GDAS) in order to improve the forecasts over the last decade, have also resulted in apparent "climate changes". These jumps in the perceived climate parameters obscure to some extent the signal of true short term climate changes or interannual climate variability. The basic idea of the CDAS/Reanalysis Project is to use a frozen state-of-the-art analysis/forecast system and perform data assimilation using past data, from 1958 to the present (Reanalysis). Moreover, the same frozen analysis/forecast system will continue to perform data assimilation into the future (CDAS), so that climate researchers can assess whether current climate anomalies are significant compared to a long reanalysis without changes in the system"--Introduction, paragraphs 1-2.
