Construction of Digital Elevation Map(DEM) integrated earth system optical model

Abstract

We have developed non-Lambertian scattering earthlike planetary system model which includes spherical atmosphere, ocean and coastline-vegetation mapping land sub-system models with independent BSDF(Bi-directional Scattering Distribution Function). Especially land scattering model was developed with directional parametric kernel method(K0, K1, K2). In this study, we suggest the new scattering land model using Digital Elevation Map(DEM) data substituting geometric parameter(K1) of the directional parametric kernel method. DEM data are used from 30-arcsec(1-km) gridded, quality-controled GLOBE(Global Land One-km Base Elevation) project. Spectral nadir reflectance and volumetric scattering component of land surface get from the observation based directional parameteric kernel data(K0, K2) from POLDER-3 mission. Introducing initial results of this study, we examined the DEM integrated earth system optical model observed by a hypothetical instrument design. The simulation case is defined for imaging of Korean Peninsula at geostationary orbit. Function). Especially land scattering model was developed with directional parametric kernel method(K0, K1, K2).
