- Abstract
The use of the Infrared Atmospheric Sounding Interferometer ( IASI) to improve short-range forecasts by the analysis of cloud variables is presented. After the retrieval of cloud microphysical variables, a one-dimensional ( 1D) version of the French convective scale model AROME is used here to discuss the persistence of the cloudy increment in the numerical weather prediction ( NWP) model. The analysis of cloud variables is shown to significantly improve the forecasts of cloud variables, temperature and humidity during 3 h. This maintenance of the cloud information in the NWP model is expected to have a high impact on the forecasts of clouds and heavy rainfall events.
