2. Data Access

The TOAR Data Portal links to serval scources to simplify the search for ozone data. The links to the data sources are grouped into four categories where currently the following data is connected:

  1. Satellite Data

    • NOAA STAR

      National Oceanic Atmospheric Administration’s STAR portfolio contains information on products, services, and tools that STAR scientists develop and maintain.

    • OMI SAO

      The Ozone Monitoring Instrument (OMI) instrument can distinguish between aerosol types, such as smoke, dust, and sulfates, and measures cloud pressure and coverage, which provides data to derive tropospheric ozone.

    • GODDARD OMI/MLS

      As members of the Aura Ozone Monitoring Instrument (OMI) science, the team develops several tropospheric ozone data products from OMI combined with Aura Microwave Limb Sounder (MLS).

    • TROPESS

      The Tropospheric Ozone and its Precursors from Earth System Sounding (TROPESS) Project is a NASA funded activity under the NASA Earth Science Mission Directorate (SMD) program called Ozone Trends Science (OTS).

    • OMI-RAL

      This dataset provides estimates of the monthly mean values of the ozone concentration, mixing ration and mole content over the globe from a large set of satellite sensors.

    • IASI+GOME2 multispectral observation of ozone

      The IASI+GOME2 is the multispectral observation of ozone at the lowermost troposphere and above from synergism of IASI thermal infrared and GOME-2 ultraviolet measurements.

    • IASI / Metop ozone Level 2 and Level 3

      The IASI AERIS Portal provides scientists with free and open access to the ozone Level 2 and Level 3 (monthly) products retrieved from the IASI/Metop observtions.

    • ESA CCI Ozone

      The Ozone_cci project has been part of the ESA Climate Change Initiative (CCI) programme since it was initiated in early 2010.

  2. Aircraft Data

    • IAGOS Data Portal

      In-service Aircraft for a Global Observing System (IAGOS) is a European Research Infrastructure for global observations of atmospheric composition from commercial aircraft.

    • ATom

      It is a dataset that provides greenhouse gasses and human air pollution conducted by NASA’s Atmospheric Tomography (ATom) mission.

    • ACT-America:L3 Merged In Situ Atmospheric Trace Gases and Flask Data

      The ACT-America airborne dataset provides merged data products acquired during flights over the central and eastern United States as part of the Atmospheric Carbon and Transport – America (ACT-America) project.

  3. Surface Data

    • TOAR database infrastructure

      The TOAR database at Forschungszentrum Jülich collects hourly data of long-term surface air quality measurements from over 10,000 stations globally.(landing page: https://toar-data.fz-juelich.de)

  4. Ozone Sonde and LiDAR Data

    • WOUDC

      The World Ozone and Ultraviolet Radiation Data Centre (WOUDC) is one of six World Data Centres which are part of the Global Atmosphere Watch programme of the World Meteorological Organization.

    • SAHDOZ

      The Southern Hemisphere ADditional OZonesondes (SAHDOZ) is an archive of sub/tropical and remote ozone-sonde data.

    • NDACC

      The International Network for the Detection of Atmospheric Composition Change (NDACC) is composed of more than 70 globally distributed, ground-based, remote-sensing research stations with more than 160 currently active instruments.

    • TOLNet

      Tropospheric Ozone Lidar Network (TOLNet) provides time/height ozone measurements from near the surface to the top of the troposphere to describe in high-fidelity their spatio-temporal distribution.

    • HEGIFTOM

      Homogenized ozone sonde free-tropospheric ozone time series for 43 sites are available on the ftp-server.

    • HEGIFTOM (LiDAR)

      Homogenized TMF tropospheric ozone LiDAR (TMTOL) time series.

  5. TOAR Data Publications

    • Access to the TOAR data publication available in B2SHARE which houses the repository of air quality and meteorological data sets related to global tropospheric ozone.
