Contributed by Helen Griffith, Dept of Geography & Environmental Science, University of Reading, UK. February 2020 has been announced as the wettest February on record for most of the UK[1]. The arrival of Storms Ciara and Dennis led to widespread flooding and the recovery is expected to cost the insurance industry over £225m[2]. Saturated soils combined with additional rainfall mean that, at the time of writing, over 100 flood warnings are still in place across England and Wales and the…

GloFAS-ERA5 reanalysis: River discharge ‘maps without gaps’ from 1979-present

GloFAS-ERA5 reanalysis: River discharge ‘maps without gaps’ from 1979-present

Contributed by Shaun Harrigan, ECMWF. In an ideal world we would have river discharge measurements for every river spanning many decades and updated in real time. We all know this is very far from reality with severe gaps in the global observing network (Lavers et al., 2019), and provides a fundamental challenge for hydrological monitoring and forecasting. A way forward pioneered in the field of meteorology and climate is to optimally combine available in situ and satellite Earth system observations…
