| Zusammenfassung |
| During the latest DISCOVER-AQ (Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality) measurement campaign taking place in Central California (Jan-Feb 2013), NO2 sondes from KNMI were deployed on board a tethersonde balloon as well as aircraft to measure high vertical resolution profiles of NO2. Data from the NO2 sondes has been compared to several other measurements of NO2 from ground, aircraft and satellite. The aim of this work is to carry out instrumental intercomparisons, compare how in-situ NO2 profiles compare to satellite column measurements of NO2 (particularly that of OMI), and to describe the impacts of urban sources of NO2 (LA Basin, Fresno-Bakersfield corridor) on semi-rural measurement sites. The KNMI OMI DOMINO NO2 product is analyzed for the duration of the field campaign including the a-priori profile shapes assumed for DOMINO. Results from the unique KNMI NO2-sonde deployed on a tethersonde vertical profiling platform during this campaign are shown and compared to the DOMINO retrieval profile shapes and related TM4/5 profile shapes. |
