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:
- Satellite Data
National Oceanic Atmospheric Administration’s STAR portfolio contains information on products, services, and tools that STAR scientists develop and maintain.
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.
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).
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.
The Aeris portal provides the multispectral observation of ozone at the lowermost troposphere and above from synergism of IASI thermal infrared and GOME-2 ultraviolet measurements.
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.
- 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.
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.
- 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)
- Ozone Sonde and LiDAR Data
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.
The Southern Hemisphere ADditional OZonesondes (SAHDOZ) is an archive of sub/tropical and remote ozone-sonde data.
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.
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.
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.
