Radar in weather prediction models
The quantification and characterization of uncertainty in weather radar measurements have become more and more important during the recent years.
Radar products are applied operationally to SMHI's Mesoscale Analysis (MESAN).
KNEP is a project at SMHI where radar data is used to make a precipitation product for nowcasting. This precipitation product works for up to six hours.
