Data

IAGOS delivers a time and spatially resolved multi-component dataset on Essential Climate Variables (ECV) and Air Pollutants. The data provide information on:

  • Distribution and long-term changes in the troposphere and lower stratosphere
  • Regular vertical profiles over major cities

An overview of the variables measured in IAGOS-CORE (continuously on several aircraft, ca. 500 flights per aircraft and year) and in IAGOS-CARIBIC (on 1 aircraft, 40-50 flights per year) is given in  the Table below. Variables in red are Essential Climate Variables (ECV). Click on a variable to see information on type and specification of instrument used. The IAGOS Data Base is used by researchers world-wide for:

  • Process studies
  • Trend analysis
  • Validation of climate and air quality models
  • Validation of space borne data retrievals

Scientific publications making use of IAGOS data are found here.

The IAGOS Data Base also contains the data from IAGOS and from the precursor projects MOZAIC and CARIBIC. Use of the IAGOS data is free for non-commercial users. Access to the data base is granted after registration and upon acceptance of the data protocol.

For operational users, particularly the COPERNICUS Atmosphere Monitoring Service (CAMS), data are provided in near real-time through the WMO Information System (WIS).
