Asymmetric Wave Distributions of Tropical Cyclones Based on CFOSAT Observations

Journal of Geophysical Research: Oceans, 2021
AbstractObservations of the China‐France oceanography satellite are used to investigate the wave distribution's asymmetry during tropical cyclone (TC) from August 2019 to August 2020. The spatial distribution of TC waves is analyzed based on an individual case, six ocean basins, and TCs categories.

Analysis of Sea Ice Results Retrieved from the Haiyang-2B and CFOSAT Scatterometers

IEEE International Geoscience and Remote Sensing Symposium
Polar sea ice monitoring is of great importance to the study of global climate change. In this paper, we propose a nonlinear SVM method to retrieve polar sea ice information using data obtained from the Chinese HY-2B and CFOSAT satellite microwave ...

Airborne experiments validating the spaceborne RFSCAT on CFOSAT

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
Airborne experiments were carried out to validate the spaceborne scatterometer. Airborne scatterometer use all the instruments of the spaceborne scatterometer to validate the system design and reliability, except the power amplifier and the antenna. The software of the scatterometer is redesigned due to the observation geometry of airborne platform ...

Directional wave spectrum estimation by SWIM instrument on CFOSAT

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
SWIM is a Ku-band radar designed for wave directional spectrum estimation. This radar operates at six incidence angles (from 0° to 10°) with a complete azimuth scanning. SWIM is currently in Phase B (concept and design phase). In [1, 2], the preliminary design and associated performance analysis have been published taking into account the end of Phase ...

The SWIM instrument, a wave scatterometer on CFOSAT mission

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
SWIM is part of the CFOSAT satellite mission payload. It is designed for the measurement of directional ocean wave spectra. It is a Ku-band real-aperture radar with 6 rotating fan-beams pointing near nadir. The main characteristics of the instrument, data, products are presented in this paper, as well as performances estimated from simulations.
