From 29 June to 1 July 2021, ECMWF will host a 3-day virtual workshop on Global hydrological modelling and forecasting.

Day 1 aims at presenting and discussing recent advances in global and large-scale hydrological modelling used in water cycle predictions up to medium-range, and in monitoring applications such as regional and global reanalyses. It will discuss the challenges involved in attaining skilful estimations of the water fluxes and reservoirs in the range of 1 to 25 km resolutions, making best use of Earth Observations to calibrate, validate or verify the model output.
