| Zusammenfassung |
| A great need exists for reliable nighttime aerosol products at high spatial
and temporal resolution. In this concept demonstration study, using
Visible/Infrared Imager/Radiometer Suite (VIIRS) Day/Night Band (DNB)
observations on the Suomi National Polar-orbiting Partnership (NPP)
satellite, a new method is proposed for retrieving nighttime aerosol optical
depth (τ) using the contrast between regions with and without
artificial surface lights. Evaluation of the retrieved τ values
against daytime AERONET data from before and after the overpass of the VIIRS
satellite over the Cape Verde, Grand Forks, and Alta Floresta AERONET
stations yields a coefficient of determination (r2) of 0.71. This study
suggests that the VIIRS DNB has the potential to provide useful nighttime
aerosol detection and property retrievals. |
