Wind Direction Retrieval Using Spaceborne GNSS-R in Nonspecular Geometry
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 A wind direction retrieval algorithm using spaceborne global navigation satellite system reflectometry (GNSS-R) in nonspecular geometry is presented. This article first focuses on investigating the influence of wind direction on the scattering strength ...

PyDDA: A new Pythonic Wind Retrieval Package [PDF]
Proceedings of the Python in Science Conference, 2019 PyDDA (Pythonic Direct Data Assimilation) is a new community framework aimed at wind retrievals that depends only upon utilities in the SciPy ecosystem such as scipy, numpy, and dask. It can support retrievals of winds using information from weather radar networks constrained by high resolution forecast models over grids that cover thousands of ...

Application of Multiple Wind Retrieval Algorithms in Nowcasting [PDF]
Atmosphere, 2015 Multiple wind retrieval algorithms are performed to retrieve wind fields, based on which radar reflectivity is extrapolated to implement nowcasting. The frequently used nowcasting algorithm COTREC (continuity of tracking radar echo by correlation), based on the reflectivity and wind retrieval algorithm GVAD (gradient velocity azimuth display), based on

Effect of precipitation on synthetic aperture radar hurricane wind field retrieval
Frontiers in Environmental Science, 2022 C-band synthetic aperture radar (SAR) with all-weather observation capability is gradually being used for the high-resolution observation of hurricane. The extreme wind speed in hurricanes is retrieved by combining the co- and cross-polarized SAR signals.
