Is there anyone on here whose brains I can pick about altimetry #SLA products? I'm particular the difference between L2P and L3 products?

2023年の海洋表面トポグラフィーサイエンスチーム会議の要約
https://science.nasa.gov/uncategorized/summary-of-the-2023-ocean-surface-topography-science-team-meeting/

2023年11月にプエルトリコのサンフアンで開催されたOcean Surface Topography Science Team Meetingについて。衛星ミッションの技術問題や将来のミッションについて議論が行われた。

S6MFやJason-3などのミッションの状況も報告された。 #NASA #JPL #altimetry

Read the European Space Agency's story about how Tero Water Level methodology developed by @isardsat, @smhi & @lobeliaearth helped reveal hundreds of previously undetectable small lakes in the #Arctic

This method uses #altimetry data to detect small water bodies anywhere in the 🌍

https://sentinel.esa.int/web/success-stories/-/new-data-analysis-technology-delivers-unprecedented-arctic-insights

We have developed a novel #AI based approach for tracking radar #altimetry measurements over ice sheets. This new AWI-ICENet1 retracker reduces the effect of signal penetration and outperforms current retracking methods. Preprint now open for discussion: https://doi.org/10.5194/tc-2023-80

The Sources Of Sea-Level Changes In The Mediterranean Sea Since 1960

https://doi.org/10.1029/2022JC019061 <-- shared paper

KEY POINTS:
• The average rate of sea-level rise in the Mediterranean Sea increased from −0.3 mm yr−1 in the period 1960–1989 to 3.6 mm yr−1 in 2000–2018
• Sterodynamic and land-mass changes both have made comparable contributions to the Mediterranean sea-level rise since 2000
• Since 2000, sea level has been rising faster in the Adriatic, Aegean, and Levantine Seas than anywhere else in the Mediterranean Sea…”

I always enjoy thinking about novel ways to combine #RemoteSensing datasets!

This new paper, led by Clément Soriot, shows that observations made by radiometers (AMSR, SMAP) strongly correlate with high-precision, #Altimetry-derived estimates of #SeaIce thickness in the #Arctic.

This technique could allow us to create a #TimeSeries of daily sea-ice thickness back to the 1980's.
