GIOŚ data - air and water quality from state monitoring
The second great public source of environmental data in Poland is GIOŚ (the Chief Inspectorate of Environmental Protection), which runs the State Environmental Monitoring (PMŚ). Its data is an excellent reference for your own measurements - and valuable reading in its own right.
What GIOŚ provides
- Air quality - measurements from the national network of stations (including PM2.5 and PM10 dust, nitrogen dioxide, ozone), presented on the air-quality portal and available through an API.
- Water monitoring - assessments of the status of water bodies and measurement data (the water-quality portal).
- Other PMŚ components (noise, soils, nature - depending on the programme).
How to use it
- The air-quality portal shows current and archival data from the stations; an API is also available, which lets you download them programmatically.
- The water-quality portal presents the status assessments of water bodies (see water bodies - JCWP) as well as monitoring data.
(The addresses and scope are sometimes updated - it is best to start from the GIOŚ pages devoted to air quality and water quality.)
What to use it for
- Reference: compare your dust sensor with the nearest official GIOŚ station to judge its reliability and set the local reading within a broader picture.
- Context: the GIOŚ water status assessments help you understand the “background” against which your measurements sit.
In practice
As with IMGW data, manually setting GIOŚ data against your own measurements can be tedious. LimnoLog can, through connectors, pull in data from public APIs (including the GIOŚ network) alongside your measurements - e.g. a reading from your own dust sensor and a measurement from a reference station on a single chart.
