This service will contribute to an improved set of the HYPE hydrological model output data, including river discharge, lake and river water level, water balance (precipitation, evapotranspiration, runoff), and total and key water storages (snow, canopy, soil, lakes, rivers). The service will also allow deriving a HYPE-based information for users, i.e. river discharge return period. The improved water availability and quality information will be published at the SMHI dissemination web-based platform (http://hypeweb.smhi.se), and it will enable and motivate water-related users by providing accurate and reliable long records of hydro-climatic information.

The service is already operational for different geographical domains including the globe. See http://hypeweb.smhi.se The various investigations under e-shape will result into improved versions of the service. In addition, a subset of the data for a pre-identified region and period (a flood event in southern Sweden in February 2020) will be shared for a joint investigation with SC5/P2.

The main outcome will be a long record of hydrological variables (including both water quantity and quality) available over different geographical domains and spatial resolution, depending on the hydrological model setup. This will include the globe, Europe and Sweden domains. The data will be available in txt format and be provided in daily or monthly temporal resolution. 

We are building competence on the DIAS platform through setting up a post-processing of the EO data to be compatible as a hydrological model input

Data and information will be available through http://hypeweb.smhi.se

There is plethora of downstream services on the water-relevant sectors which depend on accurate and reliable hydrological information at scales from regional to global. This pilot addresses the needs from a number of users (i.e. hydropower, water authorities, emergency response management centres, general public etc.). The model runs operationally at SMHI’s servers for Sweden, the pan-European and global domains providing open information to targeted users and the general public.

The different HYPE model setups are based on high resolution openly available topography, land cover and river discharge data, including delineation of both lakes and rivers, which makes it better adapted than previous setups for assimilation of EO data representing water level, water extent, evapotranspiration, snow extent and snow water equivalent. The pilot allows the assessment of EO products (from different providers) at the large scale in term of accurately representing hydrological information. 

Deferent policies apply, depending on the customers’ tailored service. The basic service based on open data is open and free, yet user targeted services are based on pay data. 

For research exploitation, there is also an open data policy. However this does not include code sharing.

We plan to advertise the pilot in the GEO/GEOSS community of users in the end of 2021.
