This study is to evaluate the sensitivity of Aerosol Optical Depth (AOD <i style="box-sizing: inherit; line-height: inherit; max-height: 100000px; color: rgb(34, 34, 34); font-family: Arial; font-size: 13px; text-align: justify;">τ</i>) to aerosol vertical profile and type, using the Moderate Resolution Imaging Spectroradiometer (MODIS)...

Modeling Top of Atmosphere Radiance over Heterogeneous Non-Lambertian Rugged Terrain

Topography affects the fraction of direct and diffuse radiation received on a pixel and changes the sun–target–sensor geometry, resulting in variations in the observed radiance. Retrieval of surface–atmosphere properties from top of atmosphere radiance may need to account for topographic effects. This study investigates how such effects can be...

Improved Surface Reflectance from Remote Sensing Data with Sub-Pixel Topographic Information

Several methods currently exist to efficiently correct topographic effects on the radiance measured by satellites. Most of those methods use topographic information and satellite data at the same spatial resolution. In this study, the 30 m spatial resolution data of the Digital Elevation Model (DEM) from ASTER (Advanced Spaceborne Thermal...

Non-Vegetated Playa Morphodynamics Using Multi-Temporal Landsat Imagery in a Semi-Arid Endorheic Basin: Salar de Uyuni, Bolivia

Playas in endorheic basins are of environmental value and highly scientific because of their natural habitats of a wide variety of species and indicators for climatic changes and tectonic activities within continents. Remote sensing, due to its capability of acquiring repetitive data with synoptic coverage, provides a unique tool to monitor and...

Evaluating MERIS-Based Aquatic Vegetation Mapping in Lake Victoria

Delineation of aquatic plants and estimation of its surface extent are crucial to the efficient control of its proliferation, and this information can be derived accurately with fine resolution remote sensing products. However, small swath and low observation frequency associated with them may be prohibitive for application to large water bodies...
