The retrospective forecasts generated for 1982 - 2009 from the first version of the climate forecast system (CFS), the fully coupled ocean-land-atmosphere dynamical seasonal prediction system, which became operational at National Centres for Environmental Prediction (NCEP), USA in August 2004, were made available at the NCEP website. This data set has proved to be extremely valuable with a large number of studies by several scientists the world over. Now that NCEP has switched over to the next version of the model, the retrospective forecasts for that model (CFS version 2) are available from NCEP. Recognizing that the retrospective forecasts of CFS version 1, which is one of the best models in the world, will continue to be an important source for researchers, CDAC offered to host this data set on the earth sciences virtual community portal on the GARUDA Grid (which is part of the National Knowledge Network programme of the Govt of India, whose aim is to interlink research institutions in India with high bandwidth connectivity). NCEP accepted this offer and have facilitated the transfer of this dataset.

While the GARUDA grid is geting ready to host this data-set, as an interim measure it is available on this website for download.

Complete Information of CFS is available at the CFS Site: http://cfs.ncep.noaa.gov/
