Calibration of CFOSAT Off‐Nadir SWIM SWH Product Based on CNN‐LSTM Model

Earth and Space Science
High‐precision observation of significant wave height (SWH) is crucial for marine research. The Surface Waves Investigation and Monitoring (SWIM) aboard the China France Oceanography Satellite (CFOSAT) provides the ocean wave spectrum that allows for the

Evaluation of HY-2C and CFOSAT Satellite Retrieval Offshore Wind Energy Using Weather Research and Forecasting (WRF) Simulations

Remote Sensing, 2023
This study simulated the spatial distribution of wind speeds and wind energy density by using the WRF model, and we used the WRF-simulated results to evaluate the sea surface wind speeds retrieved from the HY-2C and CFOSAT satellite-borne microwave ...

Evaluation of CFOSAT Wave Height Data with In Situ Observations in the South China Sea

Remote Sensing, 2023
The wave spectrometer operated by the China–France Oceanography Satellite (CFOSAT) can provide global ocean wave observation data. Although a lot of work on calibration and verification has been carried out in the open oceans dominated by swells, the ...

A Novel Sea State Classification Scheme of the Global CFOSAT Wind and Wave Observations

Journal of Geophysical Research: Oceans, Volume 129, Issue 11, November 2024.
Ocean waves are essential elements across the air‐sea interface, regulating momentum and energy transfer. The mixture of wind sea and ocean swell coupled with surface winds results in diverse sea state conditions that modify the local air‐sea interaction.

Classification of Arctic Sea Ice Type in CFOSAT Scatterometer Measurements Using a Random Forest Classifier

Remote Sensing, 2023
The Ku-band scatterometer called CSCAT onboard the Chinese–French Oceanography Satellite (CFOSAT) is the first spaceborne rotating fan-beam scatterometer (RFSCAT). A new algorithm for classification of Arctic sea ice types on CSCAT measurement data using

CFOSAT: Products Reprocessing and Contributions in Oceanography

IGARSS 2023 - 2023 IEEE International Geoscience and Remote Sensing Symposium, 2023
Since 2018, for the first time, space measurements of colocated wind vectors and wave spectral characteristics are available thanks to the French/Chinese CFOSAT mission, which carries a wind scatterometer (SCAT) and a wave scatterometer (SWIM). Four years after its launch, CFOSAT data processing has been improved to reach a high level quality, leading ...

海表温度对中法海洋卫星散射计测量的影响

Kongjian kexue xuebao, 2023
卫星散射计通过测量海表粗糙度反演全球海面风场。对于Ku波段散射计，海表粗糙不仅和海面风场相关，还受海表温度的二阶效应调制。定量研究了海表温度对中法海洋卫星（CFOSAT）散射计（CSCAT）反演风速和后向散射测量的影响。结果表明，CSCAT两种极化方式测量的后向散射系数都会受到海表温度的影响，但是垂直极化中低入射角（θ < 36°）测量的后向散射系数几乎不随温度变化。因此CSCAT的风速偏差也随海表温度的变化而变化，且随着入射角的增大和风速的减小，海表温度对风速偏差的影响程度增大 ...

A Multi‐Sensor Approach for the Characterization of Tropical Cyclone Induced Swell—Application to TC Larry, 2021

Geophysical Research Letters
Sea states are likely highly complex and variable under tropical cyclone (TC) conditions. Outrunning the inner core TC vortex, swell systems can radiate in different directions with different wavelengths.
