Vojtěch Bližňák (IAP Prague): Impact of Satellite-Derived Cloud Cover on Road Weather Forecast in the Czech Republic


Vojtěch Bližňák presents how the satellite cloud data helps forecasting road surface temperature in Czechia.


The goal of the contribution is to assess an impact of extrapolated cloud cover derived from satellite observations on forecasts of road surface temperature (RST) performed by the road weather model (RWM) FORTE. Based on road weather station measurements and forecasts of the ALADIN numerical weather prediction (NWP) model, which are used as inputs to prepare initial and boundary conditions, the RWM generates a linearly continuous forecast of RST on selected Czech highways. The work will compare the evaluation of RST forecasts generated by two model runs using NWP and satellite-derived cloud cover estimation.
