Zusammenfassung |
In anticipation of the upcoming GOES-R launch we simulate visible and
near-infrared reflectances of the Advanced Baseline Imager (ABI) for cases
of high aerosol loading containing regional haze and smoke over the eastern
United States. The simulations are performed using the Weather Research and
Forecasting (WRF), Sparse Matrix Operator Kernel Emissions (SMOKE), and
Community Multiscale Air Quality (CMAQ) models. Geostationary,
satellite-derived, biomass-burning emissions are also included as an input
to CMAQ. Using the CMAQ aerosol concentrations and Mie calculations,
radiance is computed from the discrete ordinate atmospheric radiative
transfer model. We present detailed methods for deriving aerosol extinction
from WRF and CMAQ outputs. Our results show that the model simulations
create a realistic set of reflectances in various aerosol scenarios. The
simulated reflectances provide distinct spectral features of aerosols which
are then compared to data from the Moderate Resolution Imaging
Spectroradiometer (MODIS). We also present a simple technique to synthesize
green band reflectance (which will not be available on the ABI), using the
model-simulated blue and red band reflectance. This study is an example of
the use of air quality modeling in improving products and techniques for
Earth-observing missions. |
