- SeaWinds - an overview | ScienceDirect Topics
SeaWinds is a Ku-band scatterometer onboard the QuikScat satellite, designed to measure wind speed and direction over the ice-free global oceans using microwave radiation It operates by transmitting radar pulses and analyzing their return signals, allowing for the determination of ocean wind characteristics under various sky conditions
- Tracking large tabular icebergs using the SeaWinds Ku-band microwave . . .
While SeaWinds images are relatively coarse (2–4 km) resolution compared to optical photos or SAR images, the frequent observations and visibility of icebergs within the SeaWinds images enable accurate daily tracking of large Antarctic icebergs The iceberg detection methodology has been expanded to operate in near-real-time (NRT)
- Tropical forest backscatter anomaly evident in SeaWinds scatterometer . . .
However, SeaWinds Ku-band backscatter (13 4 GHz, ~ 2 2 cm wavelength) from a closed-canopy tropical forest will be much less sensitive to underlying soil moisture dynamics than C-band backscatter from the grassland, forest, and cropland vegetation growing in the much drier climate of Spain and Portugal, due to Ku-band's shorter wavelength and
- Iceberg size and orientation estimation using SeaWinds
SeaWinds scatterometer data from 1999 to 2009 has been used to detect and track large Antarctic icebergs on a daily basis Here, we develop two estimation algorithms to supplement iceberg position reports with estimates of the iceberg's major-axis length, minor-axis length, and angle of rotational orientation
- Coastal wind retrievals from corrected QuikSCAT Normalized Radar Cross . . .
A new correction scheme named “noise regularization”, aiming at mitigating land contamination in SeaWinds scatterometer coastal Normalized Radar Cross…
- Variability in ice phenology on Great Bear Lake and Great Slave Lake . . .
The temporal evolution of the backscatter coefficient, sigma-nought (σ°) from QuikSCAT was evaluated for monitoring ice phenology on Great Bear Lake (…
- Remote sensing of snow thaw at the pan-Arctic scale using the SeaWinds . . .
Remotely sensed estimates of snow thaw offer the potential of more complete spatial coverage across remote, undersampled areas such as the terrestrial…
- Classification of new-ice in the Greenland Sea using Satellite SSM I . . .
In the ice covered waters of the Greenland Sea the polarisation ratio of QuikSCAT SeaWinds Ku-band (13 4 GHz) scatterometer measurements and the polar…
