Multi-Frequency SAR Retrieval of Sea Surface Wind Field

IGARSS 2023 - 2023 IEEE International Geoscience and Remote Sensing Symposium, 2023
This study is to present the lesson learned during the activ- ities related to the Italian Space Agency (ASI) funded AP- PLICAVEMARS project which aims at estimating sea surface wind field from L-, C- and X-band Synthetic Aperture Radar (SAR) imagery.

SEA SURFACE WIND SPEED RETRIEVAL FROM MTVZA-GYA DATA

Meteorologiya i Gidrologiya, 2023
A neural network (NN) algorithm for the sea surface wind speed retrieval from the MTVZA-GYa Russian satellite microwave radiometer measurements is presented. The algorithm is based on the physical modeling of the brightness temperature of microwave radiation in the ocean-atmosphere system using new theoretical geophysical model functions of the ...

Assimilation of ASCAT Sea Surface Wind Retrievals with Correlated Observation Errors

Journal of Meteorological Research, 2021
Data assimilation systems usually assume that the observation errors of wind components, i.e., u (the longitudinal component) and v (the latitudinal component), are uncorrelated. However, since wind components are derived from observations in the form of wind speed and direction (spd and dir), the observation errors of u and v are correlated.

New Approach to Sea Surface Wind Retrieval From GNSS-R Measurements

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
So far, GNSS-R studies on sea surface wind retrieval from Delay-Doppler Maps (DDM) have focused on the best fitting of the model to the measurements. This paper proposes a new approach to retrieve the sea surface wind using DDM deconvolution. The proposed method is based on the direct restoration of scattering coefficients from two measured DDMs. Using

Wind retrieval over the china seas using satellite synthetic aperture radar

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
The high spatial resolution and large coverage of synthetic aperture radar (SAR) offers a good opportunity to retrieve detailed wind vector information over the oceans, especially in the coast areas. In the work presented here, the wind speeds estimate is based on the data from ScanSAR aboard the Canadian satellite RADARSAT, operating at C-band with ...
