Uncertainty quantification, communication practicing and modern pedagogy of hydrological forecasts – A “Παν μέτρον άριστον” approach – Interview with Marie-Amélie Boucher

Uncertainty quantification, communication practicing and modern pedagogy of hydrological forecasts – A “Παν μέτρον άριστον” approach – Interview with Marie-Amélie Boucher

Contributed by Ilias Pechlivanidis and Marie-Amélie Boucher. Marie-Amélie Boucher has been a HEPEXer since 2007, with a strong involvement in HEPEX-related events, i.e. organizing committee member of the HEPEX 2016 workshop in Québec, and lecturer of the hydrological forecasting course for the Early Career Scientists (ECS) at EGU2017 in Vienna and IAHS 2019 in Montréal, and others. On a scientific level, she is one of the members that brings knowledge to the community on Nordic hydrological processes and forecasting practices…

Follow the HSAF HEPEX workshop live, in person or streaming

In just a couple of weeks it is time for the joint H SAF and HEPEX workshop on using remote sensing for hydrological applications, this time enticingly named “Satellite inspired hydrology in an uncertain future”. The workshop is a follow-on from the workshop five years ago on “Coupled hydrology“, so it is time to see how far the community has got in terms of using satellite data in hydrological applications and what the challenges are for the future. We welcome…

Hydrometeorological forecast verification: the detail matters!

Hydrometeorological forecast verification: the detail matters!

Contributed by Seonaid Anderson, CEH.  Spending time and effort developing a novel hydrological ensemble prediction system, demonstrating its value, comparing with existing systems, justifying all that effort… there are many reasons why we verify our ensemble prediction systems. Before we dive into the number crunching, a few obvious questions need to be asked. What period to use for evaluation? This is often as long as possible, while maintaining relevance to the current application and subject to the usual computing constraints. What…

IAHS conference: live feed

IAHS conference: live feed

Contributed by Marie-Amélie Boucher (Université de Sherbrooke) and Maria-Helena Ramos (Irstea) Cannot attend IAHS conference in Montreal this week? Follow us then! During this week, from Monday 8 to Saturday 13, we will be posting some lines and photos every day in the HEPEX blog, directly from the 27th IUGG General Assembly, at the Palais des Congrès in Montréal, Canada. You can post comments day by day too, and we will try to answer them all. Just remember: we will…

OpenIFS@home: Using citizen science to improve our understanding of weather and hydrological forecasts

OpenIFS@home: Using citizen science to improve our understanding of weather and hydrological forecasts

The history of HEPEX is deeply connected to ensemble forecasting and uncertainty analysis. Indeed, none of us could even imagine a forecast without uncertainties (apart from McFool). One direction of research is to investigate the value in improving forecasts using a coupled system and truly understand the interactions between the atmosphere and the land surface whilst analysing the associated uncertainties. However, any analysis is limited by the resources one has available. To run a large number of ensembles, one would…
