Investigation of the Effect of Low Level Maritime Haze on DMSP VHR and LF Imagery
Abstract
An efficient modeling approach is described to simulate the dependence of remotely sensed radiances at visible and near infrared wavelengths (04.-1.1 microns) on meteorological variables such as relative humidity, wind speed, and visual range. Model elements include: (1) atmospheric opacity due to Rayleigh scattering and gaseous absorption; (2) physical modeling of aerosol size distribution; (3) aerosol optical properties calculations; and (4) implementation of radiative transfer theory. Sensitivity analyses are performed for these variables in the context of examining modeled meteorological influences in the marine environment on the DMSP VHR and LF sensors. The sensitivity of emergent radiances in the near infrared spectral windows to the presence of relative humidity and wind speed dependent coarse mode aerosols of oceanic origin is demonstrated.
