Numerical Weather Prediction (NWP) data are the most familiar form of weather model data. NWP computer models process current weather observations to forecast future weather. Output is based on current weather observations, which are assimilated into the model’s framework and used to produce predictions for temperature, precipitation, and hundreds of other meteorological elements from the oceans to the top of the atmosphere.
