Application of Traditional and Novel Cloud Property Retrieval Techniques on Landsat TM Data over SGP

چکیده
With the recognition in recent years of the influence of three-dimensional (3-D) radiative transfer on cloud optical property retrievals, interest in the measurements of the Thematic Mapper (TM) radiometer aboard the Landsat satellite has been renewed. This instrument provides a unique high-resolution data set where the effects of 3-D cloud structure are expected to be prominent. The purpose of this paper is to examine the real world application of the Nonlocal Independent Pixel Approximation (NIPA) of Marshak et al. (1998), and to suggest a new Independent Pixel Approximation (IPA) using normalized reflectivity differences. Our satellite data set consists of a full Landsat scene over the Atmospheric Radiation Measurement (ARM) Program’s Southern Great Plains (SGP) site.

Cloud segmentation is a critical pre-processing step for any multi-spectral satellite image application. In particular, disaster-related applications e.g., flood monitoring or rapid damage mapping, which are highly time and data-critical, require methods that produce accurate cloud masks in a short time while being able to adapt to large variations in the target domain (induced by atmospheric c...

The Moderate Resolution Imaging Spectroradiometer (MODIS) on board the NASA Terra satellite has been collecting global data since March 2000 and the one on the Aqua satellite since June 2002. In this paper, cirrus cloud properties derived from ground-based remote sensing data are compared with similar cloud properties derived from MODIS data on Terra. To improve the space–time correlation betwe...

Anthropogenic land use activities are significantly contributing to the ecological degradation of the Earth system. Therefore, having actual and reliable land cover information is fundamental to study the impact of such an ecological degradation on our future welfare. High spatial resolution sensors, such as Landsat TM, are typically used to derive land cover information from local to regional ...
