Model output statistics
From Glossary of Meteorology
model output statistics
(Abbreviated MOS.) For a numerical weather prediction model, statistical relations between model-forecast variables and observed weather variables, used for either correction of model-forecast variables or prediction of variables not explicitly forecast by the model.
They have often taken the form of multilinear regression equations derived by screening potential model-forecast variables as predictors. The method produces forecasts of weather variables that to some extent account for the random and systematic errors in the numerical weather prediction model.
