Miljödata

Miljödata, or environmental data, refers to information about the environment collected to support monitoring, analysis, and decision making. It covers physical, chemical, biological, and socio-environmental indicators such as air and water quality, climate variables, biodiversity, land use, emissions, and energy consumption.

Data sources include government agencies, universities, research institutes, industry, non-governmental organizations, and citizen science. Data may be generated by ground-based sensors, meteorological stations, sample analysis, satellite observations, and enumeration surveys.

Standards and interoperability: In Europe, the INSPIRE directive seeks to harmonize spatial data under common metadata and sharing rules; ISO 19115/19139 metadata standards are commonly used; the European Environment Agency coordinates open data initiatives. Metadata describes data provenance, methods, temporal and spatial coverage, quality, and access rights.

Formats and access: Miljödata is stored in formats such as CSV, NetCDF, GeoJSON, or GeoTIFF, and delivered through APIs, data portals, or web services (for example WMS/WFS). Open data licenses, such as CC0 or open data agreements, facilitate reuse.

Applications and challenges: Miljödata supports environmental monitoring, climate research, policy development, risk assessment, and urban planning. Challenges include gaps in coverage, varying data quality, differing temporal and spatial resolutions, fragmentation across institutions, and ensuring data quality, privacy (where relevant), and long-term accessibility.

Notable sources include the Swedish Environmental Protection Agency (Naturvårdsverket), the Swedish Meteorological and Hydrological Institute (SMHI), and the European Environment Agency (EEA).
