Hello,
I am a 77 year-old physical oceanographer interested by a dramatic low having been observed on the Polynesian Maupiti Island (16.4 °S-152.3 °W) exactly during the SWOT path of Dec. 30, 2023.
I fully rely on the SLA L3 data accuracy at the 250-m pixel level that, I believe, is demonstrated by permanent small scale structures such as the bean-shaped low in the west of the island displayed on the https://swot-calval.oceandatalab.com/ site. Unfortunately, these permanent small scale structures demonstrate that the considered geoid is not fine enough and I would like to perform averages of the SLA L3 data as they are computed and presented to try specifying them and inferring the oceanic signal (considered to be the small scale variable part and not considering the large scale part due to the tides and the atmospheric pressure) in a relatively small latitudinal interval (16.4 to 17.0 °S) where I expect eddies to have possibly occurred
Could it be possible to obtain Excel files of the SLA L3 pixels in the form Lat-Lon-SLA for a dozen descending paths, ideally without any error, in this latitudinal interval?
Since this would necessitate some extra work, I could specify the dates of these convenient paths and send a manuscript presenting the observations and what has already been done with SWOT data (those on Dec. 30, 2023 are the lowest ever observed) and nadir data (that indicate a 200 km eddy nearby) with the help of a colleague from LEGOS who has no more time to help me.
And we could exchange directly using our e-mails...
With my many and sincere thanks in advance.
