| Zusammenfassung |
Results of a new methodology for retrievals of surface particulate matter
concentration (PM10) from satellite reflectance measurements over
Germany are presented in this paper. The retrieval derives effective radii
from Ångström-α exponents and benefits from the fitting of a
smooth spectral slope from seven MERIS spectrometer channels. Comparisons
with ground measurements from the air quality surveillance show standard
deviations of 33.9% with −18.9% bias over Hamburg. Over rural sites a
standard deviation of 17.9% (bias 12.9%) is reached.
We discuss critically limitations and potential applications of the
retrieval. Additionally, we talk about the aspects at comparing of retrieved
particulate matter with ground station measurements. |
