An Improved Local Gradient Method for Sea Surface Wind Direction Retrieval from SAR Imagery
Sea surface wind affects the fluxes of energy, mass and momentum between the atmosphere and ocean, and therefore regional and global weather and climate. With various satellite microwave sensors, sea surface wind can be measured with large spatial coverage in almost all-weather conditions, day or night. Like any other remote sensing measurements, sea surface wind measurement is also indirect. T...
متن کاملDerivation of Sea Surface Wind Directions from TerraSAR-X Data Using the Local Gradient Method
Derivation of sea surface wind direction is a key step of sea surface wind retrieval from spaceborne Synthetic Aperture Radar (SAR) data. This technical note describes an implementation of the Local Gradient (LG) method to derive sea surface wind directions at a scale of a few kilometers from X-band spaceborne SAR TerraSAR-X (TS-X) data in wide swath mode. The 180 ̋ ambiguity in the derived sea ...
متن کامل$LG$-topology
In this paper, we introduce a new model of point free topology for point-set topology. We study the basic concepts in this structure and will find that it is naturally close to point-set topology.
متن کاملWind Direction Extraction from SAR in Coastal Areas
This paper aims to illustrate and test a method, based on the Two-Dimensional Continuous Wavelet Transform (2D-CWT), developed to extract the wind directions from the Synthetic Aperture Radar (SAR) images. The knowledge of the wind direction is essential to retrieve the wind speed by using the radar-backscatter versus wind speed algorithms. The method has been applied to 61 SAR images from diff...
متن کاملModuli stacks Lg,S
This paper is a sequel to the paper by A. Losev and Yu. Manin [LoMa1], in which new moduli stacks of pointed curves were introduced. In particular, the structure sections are divided into two groups, and the sections of the second group are allowed to intersect. The homology of these stacks form components of extended modular operad which will be further studied in [LoMa2]. In this paper the ba...
