Title:
Operational Danish Road Weather Forecasting using High Resolution Satellite Data
Abstract:
Improvements in performance of the Danish Road Weather Model system due to incorporation and assimilation of cloud observations from satellites and conventional data are discussed. Both conventional observations and NOAA and MSG-1 satellite data were assimilated using a nudging technique and the results were verified for a two weeks period. Additionally the derived cloud mask from the NOAA satellite was compared with conventional observations. The results indicate that use of cloud data can be used to improve forecasts of the road surface temperature in particularly for short term forecasts. It is also emphasized that NOAA data for some days differ from conventional data and should be used with care in certain situations.
