Global, continental and other large scale hydrological research is very important in many different contexts. Examples include increasing understanding of the climate system and water cycle, assessment of water resources in a changing environment, hydrological forecasting and water resource management.

We invite contributions from across the atmospheric, meteorological and hydrological communities. In particular, we welcome papers that address advances in:

(i) understanding and predicting the current and future state of our global and large scale water resources;

(ii) use of global earth observations and in-situ datasets for large scale hydrology and data assimilation techniques for large scale hydrological models;

(iii) understanding and modelling of extremes: droughts, floods;

(iv) representing/evaluating different components of the terrestrial water cycle fluxes and storage (e.g. soil moisture, snow, groundwater, lakes, floodplains, evaporation, river discharge) and their impact on current/future water resources and atmospheric modelling.
