A Lookup Table-Based Method for Estimating Sea Surface Hemispherical Broadband Emissivity Values (8–13.5 μm)

open access: yesRemote Sensing, 2017
Sea surface hemispherical broadband emissivity (BBE, 8–13.5 μm) is a vital parameter for calculating surface radiation budgets. Such data are currently unavailable.

Long-Term Trends of Sea Surface Wind in the Northern South China Sea under the Background of Climate Change

open access: yesJournal of Marine Science and Engineering, 2021
The long-term trends of sea surface wind are of great importance to our understanding of the effects of climate change on the marine environment. In the northern South China Sea (SCS), the long-term changes in coastal sea surface wind are not well ...

The sea surface temperature deviation at very low wind speeds; is there a limit? [PDF]

open access: yesTellus, 1977
Laboratory and field measurements of the temperature drop across the boundary layer at the upper surface of evaporating and cooling water in turbulent free convection show that greater values are possible than previously indicated. An upper limit on the surface temperature deviation is imposed only by the maximum heat loss occurring in the earth's most

Sea Surface Wind Retrievals from SIR-C/X-SAR Data: A Revisit

open access: yesRemote Sensing, 2015
The Geophysical Model Function (GMF) XMOD1 provides a linear algorithm for sea surface wind field retrievals for the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR).

Research on Wind Speed Inversion Method for X-Band Networked SAR Satellite

open access: yesJournal of Marine Science and Engineering, 2020
Synthetic aperture radar (SAR) can extract sea surface wind speed information. To extract wind speed information through the geophysical model function (GMF), the corresponding wind direction information must be input.

New Ku-Band Geophysical Model Function and Wind Speed Retrieval Algorithm Developed for Tiangong-2 Interferometric Imaging Radar Altimeter

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
A Ku-band geophysical model function for wind speed retrieval named as KuLMOD-H is proposed based on the quasi-specular reflection model for the Chinese Tiangong-2 Interferometric Imaging Radar Altimeter (TG2-InIRA), which can be used to retrieve the ...

Numerical Study on the Influence of Tropical Cyclone Characteristics on the Sea State and Sea Surface Roughness inside the Tropical Cyclones

open access: yesJournal of Marine Science and Engineering, 2022
The development of wind wave (i.e., sea state) inside an intense tropical cyclone (TC) is the dominant contributor to the sea surface roughness and thus significantly impacts the air–sea interaction. The sea state is known to vary with TC characteristics

Contribution of Wind Speed and Sea-Air Humidity Difference to the Latent Heat Flux-SST Relationship

open access: yesOcean-Land-Atmosphere Research, 2022
This study investigates contributions of wind speed and sea-air humidity difference (dq) terms to the seasonal change and time scale dependence in the relationship between surface latent heat flux (LHF) and sea surface temperature (SST) using daily data.

Characteristics and Applications of the Ground-Based X Band Low Elevation Angle Brightness Temperatures under Low Sea State Based on Measured Data

open access: yesRemote Sensing, 2020
In ground-based microwave radiometer remote sensing, low-elevation-angle (−3°~3°) radiation data are often discarded because they are considered to be of little value and are often difficult to model due to the complicated mechanism.
