Short-range Forecasting Methods of Fog, Visibility and Low Clouds - Phase I Report

The purpose of this report is to make available the outcome of the work of COST Acton 722 ‘Short-range forecasting of fog, visibility and low clouds’, which was carried out from 2002 to 2003. During this period, an inventory of existing forecast methods and ongoing projects was made and an evaluation of requirements from customers and from forecasters was prepared. These results will be used for the next phases of COST Action 722. However, they could be also useful for a wider community interested in the processing of input data (in-situ, satellites), numerical and statistical forecasting and in application purposes.
