| Zusammenfassung |
| A new technique to retrieve the particulate matter vertical columns from
spaceborne observations is described. The method is based on the
measurements of the spectral aerosol optical thickness (AOT). The spectral
slope of the derived aerosol optical thickness is used to infer the size of
particles, which is needed (along with the absolute value of AOT) to
determine corresponding vertical columns. The technique is applied to the
case of a cloudless atmosphere over Germany and results are compared with
ground-based observations. Several assumptions are made in the retrieval
process such as the prescribed phase function, single scattering albedo, the
refractive index of aerosol, and the half-width of the size distribution. |
