PArtnership with ChiNa on SpaceDAta
WP1 - Remote Sensing Observations [Months: 1-36]
The overall goal is:
• to provide a consistent historical satellite data set to the project,
• to improve the retrievals over China,
• to validate and inter-compare
the satellite data,
• and to provide a limited rapid
response data set for
monitoring of on-going changes.
Introduction
5
T1.1 - Collection of existing satellite data sets [Months: 1-12]
IUP-UB, ULEIC, ULB, NSMC Sources of satellite remote sensing data available for use in the project from
different sources (NASA, US partners, MACC-II project etc.) and publicly
available archives will be collected and prepared for the project.
T1.2 - First version of satellite data set [Months: 1-12]
IUP-UB, CNRS, ULB, NSMC Preparation of historical data set from
• GOME, SCIAMACHY and GOME-2 (NO2, SO2, HCHO),
• IASI (O3, CO, NH3)
• TOU and SBUS (O3)
covering 1996 – 2012 as far as satellite data is available. This data set
will be mainly based on existing retrievals.
What are the main tasks in WP1?

IUP-UB contribution for Panda
NO2 timeseries over China (30-40°N, 110-123°E) from different sensors, NRT data:
Same trend for all instruments, 2014 first year with clear decrease in
NO2 columns. OMI lower due to noon orbit.
17
IUP-UB contribution for Panda
Example of NO2 tropospheric columns delivered for D1.2:
• Data converted and uploaded in NetCDF format (as decided at kick-off meeting)
• CF conventions compliant (http://cfconventions.org/)
• Available on IUP-UB server, accessible from PANDA-webpage
http://www.marcopolo-panda.eu/results/toolbox/satellite-observations/
• Password-protected (for password contact [email protected])
18
IUP-UB: Future plans
• Extraction of NO2 timeseries over all Panda and MarcoPolo ground-stations
(work already started, results will be provided on IUP server soon)
• Outlook: Data product for vertical distribution of NO2 under developement
(preliminary version will be possibly available as timeseries over ground stations)
Validation of satellite data (Task 1.4 with Chinese partners)
Presentation of Andreas Hilboll during validation workshop on Wednesday
Improvement of data sets, e.g.:
• Better aerosol treatment
• Better inputs for AMF
High resolution a priori data bases link to S5P and QA4ECV projects
Better a priori profiles model input from Panda?
Boundary layer flag to identify scenes with NO2 in BL
19
IUP-UB: NO2 boundary layer flag
• NO2 BL flag uses wavelength dependence of signal from lower atmosphere
• Automatic separation of NO2 in stratospehre / upper troposphere and BL
• Noise is a problem
• Potential for quantitative use is currently being investigated

Pollution event as seen by IASI (January 12, 2013)
• Extreme concentrations in
several pollutants (CO, SO2, NH3)
• Temperature inversion increased sensitivity of IASI at surface level
