“ Climate Forecast System (CFS) An animation of CFSR global atmospheric precipitable water for March 1–15, 1993, in 12-hourly intervals An animated image of CFSR global atmospheric precipitable water for March 1–15, 1993, in 12-hourly intervals. (One-hourly CFSR data was down-sampled to every 12 hours to keep image size down.) This image was produced with the Grid Analysis and Display System and ImageMagick. The Climate Forecast System (CFS) is a model representing the global interaction between Earth's oceans, land, and atmosphere. Produced by several dozen scientists under guidance from the National Centers for Environmental Prediction (NCEP), this model offers hourly data with a horizontal resolution down to one-half of a degree (approximately 56 km) around Earth for many variables. CFS uses the latest scientific approaches for taking in, or assimilating, observations from data sources including surface observations, upper air balloon observations, aircraft observations, and satellite observations.” https://www.ncdc.noaa.gov/data-access/model-data/model-datasets/climate-forecast-system-version2-cfsv2 .
