Today, a new publication about the BALTEX dataset of GRDC has been released in Frontiers in Environmental Science. The article “The BALTEX dataset of the Global Runoff Data Centre (GRDC): a dataset of river discharge draining into the Baltic Sea” is part of the special issue “New Challenges for Baltic Sea Earth System Research”, which has been compiled in the framework of last year’s Baltic Earth Conference from 13-17 May 2024 in Jūrmala, Latvia.
The original BALTEX dataset has been collected in the framework of the Baltic Sea Experiment (BALTEX) as part of the Global Energy and Water Exchanges project (GEWEX), initiated in the 1980s under the World Climate Research Programme (WCRP). For this purpose, the first river discharge dataset of BALTEX was compiled and made available by the Swedish Meteorological and Hydrological Institute (SMHI) through the BALTEX Hydrological Data Centre. In 2015, the BALTEX database, comprising data from 592 monitoring stations, was transferred to the Global Runoff Data Centre (GRDC) to ensure long-term support and regular updates as part of GRDC’s ongoing responsibilities providing river discharge time series, even beyond the active phase of BALTEX.
Since the integration of the BALTEX database into GRDC in 2015, the curation and update of the BALTEX dataset is embedded in the regular work of GRDC. With this approach, the number of stations in the Baltic Sea catchment area of the BALTEX dataset was expanded by 126 stations, receiving regular, up-to-date time series updates. The aim of the data report is to provide an overview about the BALTEX dataset and its extension in order to provide a complete as possible hydrological river discharge database for the Baltic Sea.
