Steps

  1. Call GetCapabilities at uk-air.defra.gov.uk/data/sos/service?service=SOS&request=GetCapabilities to discover available sensors/offerings
  2. Use GetObservation (KVP over HTTP GET, or JSON/POX/SOAP POST) to request sensor data encoded in OGC Observations & Measurements 2.0
  3. Use DescribeSensor to get sensor metadata as SensorML 1.0.1, or GetFeatureOfInterest for the monitoring station's GML representation
  4. Consult the SOS Pollutants reference page to map pollutant codes before filtering a request
  5. For simpler bulk/desktop retrieval instead of raw SOS queries, use the openair R package's import functions, which pull from the same UK-AIR data archive
