Satellite Observation of Atmospheric Compositions for Air Quality and Climate Study
Description
Atmospheric compositions, including greenhouse gases (CO 2, CH 4, O 3, and N 2O) and polluted trace gases (CO, NO 2, and SO 2) and particles (aerosol), have played important roles in affecting air quality, public health, and climate. Recent advances in remote sensing observation, especially the development of hyperspectral space-borne satellite sensors, enable us to make much better measurements of these compositions over the globe with high spatial and temporal coverage. More and more studies have proven the value of these satellite remote sensing products in monitoring the air quality and climate change, which include the comparison of satellite observations with ground-based in situ and remote sensing observation, aircraft measurements, and model simulations, as well as the inverse modeling, to improve the quantification of source or sinks of these compositions.
Potential topics include, but are not limited to:
- Retrieval algorithms and analysis of the trace gases products from different sensors, such as AIRS, IASI, TES, CrIS, GOSAT/TANSO, SCIAMACHY, GOME-2, OMI, and OMPS
- Retrieval of aerosol properties (such as optical depth, particle size and distribution, and compositions) from different sensors, such as MODIS, MISR, and VIIRS, and use of the satellite data s to derive the PM10 and PM2.5 for air quality and public health study
- Validation of the products using ground-based and airborne measurements and cross-validation of product among these different sensors and the data-fusion
- Applications of satellite remote sensing data alone, and/or combined with other measurements and model simulation data to study sources of these trace compounds, as well as its transport under the impact of large scale circulation and stratosphere-troposphere exchange; analysis of their seasonal cycles and trends and interaction with air quality and climate change
