The World Meteorological Organization (WMO) in collaboration with the International Sava River Basin Commission (ISRBC) organized a Capacity Building Workshop on Hydrological Data Exchange, Standardization, and Interoperability in Region VI of WMO, on 25 and 26 January (online) and 29 and 30 January 2024 (in person). The face-to-face training took place in the premises of ISRBC in Zagreb.

The workshop initiated by the Permanent Expert Group for Hydrological and Meteorological Issues of the ISRBC and in accordance with the Memorandum of Understanding between the WMO and ISRBC was attended by representatives of hydrometeorological services from the Sava River basin, i.e. Sava HIS data providers. Representatives of hydrometeorological services from the Danube River basin from Romania and Czech Republic as well as experts from the International Commission for the Protection of the Danube River (ICPDR) also participateed at the workshop. Altogether 26 participants were in Zagreb in presence (including trainers and organizers), and additionally 7 trainers joined online.
The training was supported with trainers from the WMO expert groups (Joint Expert Team on Hydrological monitoring-JET-HYDMON), Open Geospatial Consortium-Hydrology Domain Working Group (OGC-HDWG) and WMO partner organizations providing technical solutions like WHOS DAB (Earth and Space Science Informatics laboratory, ESSI-lab) of the National Research Council of Italy - Institute of Atmospheric Pollution Research (CNR-IIA)) and OSCAR/Surface platform (MeteoSwiss), UK Centre for Ecology and Hydrology (UK CEH), and ISRBC.
Achievements​:

• The workshop presented accessing and sharing procedures to the hydrological, meteorological data and metadata using relevant standards and principles supported by WMO through different tools, i.e. Sava HIS, Danube HIS, WIGOS, OSCAR, WHOS as well as their interoperability between each other and with other tools​.
• The workshop discussed existing policy on the exchange of hydrological and meteorological data and information, particularly in the Sava River basin, through the implementation of WMO Unified Data Policy​.
• The workshop provided a hands-on training on editing existing data and metadata within Sava HIS, including the export of data through the Water ML 2.0 web services, as well as registration of hydrological stations in OSCAR and allocation of WIGOS Station Identifiers​.
• The workshop also explored the implementation of the Water ML 2.0 (including Part 5 for water quality), the WMO Hydrological Status and Outlook System (HydroSOS), EW4All initiative and their linkages to WHOS.
