D1.4 - Report on WMO GTS datasets made available for non-GTS connected users and on new datasets ingested into WMO GTS based on user requirements

he Arctic PASSION project is described in more detail in the project website which is available at https://arcticpassion.eu/. The purpose of Arctic PASSION is creation and implementation of a coherent, integrated Arctic observing system. This implies integrating already existing observing systems in a system of systems approach as well addressing gaps in the current observing system. Arctic PASSION will generate data through the project implementation, but equally important is to map and establishaccess to already existing datasets in support of the pilot services and other activities of Arctic PASSION. Arctic PASSION promised in the proposal to make existing data, that are currently difficult to access, more readily available. This was specifically referring to data available in the real time exchange of data within the world meteorological Organisation (WMO) and is limited to the data that are published as free and open data. A more thorough description of the real time exchange of data and which data that are available is given in section 2.
