An overview on SAR measurements of sea surface wind
Progress in Natural Science, 2008 Studies show that synthetic aperture radar (SAR) has the capability of providing high-resolution (sub-kilometer) sea surface wind fields. This is very useful for applications where knowledge of the sea surface wind at fine scales is crucial. This paper aims to review the latest work on sea surface wind field retrieval using SAR images.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 The technology of retrieving sea surface wind field from spaceborne synthetic aperture radar (SAR) is increasingly mature. However, the retrieval of the sea surface wind field related to the precipitation effect is still facing challenges, especially the

Wind Profiles over the Sea and the Drag at the Sea Surface [PDF]
Australian Journal of Physics, 1956 Wind speeds were measured at heights up to 13 m over the sea by means of anemometers mounted on a mast attached to the jib-boom of a small vessel and another on the foremast cross-trees. The vertical temperature gradient and air/sea temperature differences were also observed.

Scatterometer Sea Surface Wind Product Validation for HY-2C
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 The Chinese HY-2C satellite was launched on Sep. 21, 2020, carrying the new Ku-band scatterometer (HSCAT-C). Different from the other currently operating scatterometers, the HSCAT-C is in a nonsun-synchronous orbit and as such it will be useful for the ...
