Spatial Feature Reconstruction of Cloud-Covered Areas in Daily MODIS Composites

Spatial Feature Reconstruction of Cloud-Covered Areas in Daily MODIS Composites

The opacity of clouds is the main problem for optical and thermal space-borne sensors, like the Moderate-Resolution Imaging Spectroradiometer (MODIS). Especially during polar nighttime, the low thermal contrast between clouds and the underlying snow/ice results in deficiencies of the MODIS cloud mask and affected products. There are different approaches to retrieve information about frequently ...

Analysis of the Spatial Continuity of Vegetation-covered Areas

Recently, it is required to investigate the distribution of vegetation-covered areas on a regional scale for not only the improvement of urban environment but also the conservation of ecosystem. The spatial continuity of vegetation-covered areas like a green corridor plays an important role for the preservation of ecological balance especially. For the analysis of the spatial distribution of ve...

Estimation of Daily Mean Air Temperature from Modis Lst in Alpine Areas

This study is aimed at demonstrating the feasibility of the MODIS Land Surface Temperature (LST) product as a source for calculating spatially distributed daily mean air temperature to be used as input for hydrological or environmental models. The test area is located in the Italian Alpine area. The proposed procedure solves, by empirical approaches, the problem of relating LST to the Air Tempe...

Evaluation of Sub-Pixel Cloud Noises on MODIS Daily Spectral Indices Based on in situ Measurements

Cloud contamination is one of the severest problems for the time-series analysis of optical remote sensing data such as vegetation phenology detection. Sub-pixel clouds are especially difficult to identify and remove. It is important for accuracy improvement in various terrestrial remote sensing applications to clarify the influence of these residual clouds on spectral vegetation indices. This ...
