8 months ago For developing/testing the configuration, reanalysis products are available and Sarah Wakelin has assessed these, ESSD - GloFAS-ERA5 operational global river discharge reanalysis 1979-present dataset is good for Europe but JRA's rivers discharge is better for Global ocean. CO10 development tests will be forced by ERA5 and run with associated GloFAS.
Copied from an e-mail dating from 27 April 2023 by @sberthou regarding AMM15: Shorter term plan (~2026, PS49) is to develop a river product from the operational forecast (probably a mix of global (Europe) and regional (UK) for OOFS. Challenges are to get good river quality from the default regional atmosphere-land configurations that we have, which is not quite there yet. There are tensions between having a land model which provides good rivers and a land model which provides good lower boundary condition for the atmosphere. At the Met Office, the latter had always priority, so we're working on combining both. Longer term plan: when regional coupled system becomes operational (on Gen2, after 2028, with LFRic at atmosphere), the aim is to get the rivers from the atmosphere-land forecast directly into the ocean (at least for the UK).
