| Zusammenfassung |
| As an update to our previous use of the collection 4 Moderate Resolution
Imaging Spectroradiometer (MODIS) over-ocean aerosol optical depth (AOD)
data, we examined ten years of Terra and eight years of Aqua collection 5
data for its potential usage in aerosol assimilation. Uncertainties in the
over-ocean MODIS AOD were studied as functions of observing conditions, such
as surface characteristics, aerosol optical properties, and cloud artifacts.
Empirical corrections and quality assurance procedures were developed and
compared to collection 4 data. After applying these procedures, the
Root-Mean-Square-Error (RMSE) in the MODIS Terra and Aqua AOD are reduced by
30% and 10–20%, respectively, with respect to AERONET data. Ten years
of Terra and eight years of Aqua quality-assured level 3 MODIS over-ocean
aerosol products were produced. The newly developed MODIS over-ocean aerosol
products will be used in operational aerosol assimilation and aerosol
climatology studies, as well as other research based on MODIS products. |
