Retrieval of Meso-Scale Wind Field: Simulation and Performance for Wind

Coherent Laser Radar, 1995
Meso-scale meteorology received an increased interest in the past decade and prompts new studies supported by both experimental and modeling works. In the frame of this effort the scientific communities in France and Germany proposed to developed the WIND project (1) to fly an airborne Doppler lidar.

TRMM Active/Passive Ocean Vector Wind Retrievals

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
This paper presents a novel ocean vector wind (OVW) retrieval algorithm that uses the Precipitation Radar (PR) and the TRMM Microwave Imager (TMI) on board of the Tropical Rainfall Measuring Mission (TRMM) satellite. In this paper, the modified 2nd Stokes parameter (weighted difference of V & H-pol Tb’s) is used to cancel the atmosphere, which enhances

The effect of wind speed on SST retrieval

2009 IEEE Aerospace conference, 2009
Many studies have been performed to retrieve the sea surface temperature (SST). However, the researchers studied only the effect of brightness temperature difference, observation angle and water vapor content. The sea surface emissivity (SSE) is normally considered as unity or constant.

Wind retrieval for GNSS reflectometry from techdemosat-1

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
The main purpose of this study is to propose and validate a new algorithm for wind speed retrieval over the ocean using Global Navigation Satellite System-Reflectometry (GNSS-R). The proposed method is based on a Least Squares (LS) estimation from the volume of the scattered power function.

A modified wind vector retrieval algorithm for polarimetric scatterometer

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
Experiments and theoretical analysis demonstrate that the polarimetric scatterometer has the potential in enhancing the accuracy of the wind vector retrieval. However, currently, there is no special wind vector retrieval algorithm for the polarimetric scatterometer.

Wind Field Retrieval and Display for Doppler Radar Data

2008
Doppler radars are useful facilities for weather data gathering. In this paper, we propose a visualization pipeline to extract and display horizontal wind fields for Doppler radar data. At first, the input radar data are filtered with adaptive filters to reduce noise and enhance features.
