In this paper, we aimed to clarify the problem of foam coverage dependence on wave fetch, which is interest in satellite microwave radiometry, but for controversial results were reported previously. The classical approach investigating developing waves was applied. That is, are considered as coming from coast under approximately constant wind velocity. study includes two scenes intensive kataba...
Land surface albedo plays an extremely important role in the energy budget, by determining proportion of incoming solar radiation, which is available to drive photosynthesis and heating, that reflected directly back space. In northern high latitude regions, snow-covered vegetation open, leafless forest canopies winter, quite high, while boreal evergreen conifers can either be low (even with ext...
Multi-temporal analysis is one of the main applications of remote sensing, and Landsat imagery has been one of the main resources for many years. However, the moderate spatial resolution (30 m) restricts their use for high precision applications. In this paper, we simulate Landsat scenes to evaluate, by means of an exhaustive number of tests, a subpixel registration process based on phase corre...
The Landsat-8 Operational Land Imager (OLI) was radiometrically calibrated prior to launch in terms of spectral radiance, using an integrating sphere source traceable to National Institute of Standards and Technology (NIST) standards of spectral irradiance. It was calibrated on-orbit in terms of reflectance using diffusers characterized prior to launch using NIST traceable standards. The radian...
