Data to be Used
• UKMO Buoy data
• UK Tide Gauge data
Coverage:
NE Atlantic
Time Period: To be defined
Description:
Optimal SAR Re-tracking
Methodology and Validation over Open Ocean
The
SAR retracking methodology will be developed and optimized using
internal consistency tests and comparisons against independent data
from other satellites (e.g. Jason-2) and in situ measurements (e.g.
offshore wave buoys).
Optimal SAR Re-tracking
Methodology and Validation over Coastal Ocean
We
take advantage of the extensive in situ measurements of waves and sea
level from inshore buoys and tide gauges along the south coast of the
UK to perform a more in depth validation of the Cryosat-2 SAR data.
Retracked SSH will be corrected for geophysical effects (e.g. wet
tropospheric delay) using the corrections in the ESA products and new
corrections developed within CP4O. The proximity of in situ wave and
sea level measurements will afford a first look at the performance of
C2 SAR against tide gauges in different sea states. Particular
attention will be give to finding occurrences of swell from different
directions to try to distinguish any possible impact on SAR waveforms
and retrieved range.
