[ecco-support] [EXTERNAL] Questions about differences among different ECCO products

[Wang, Ou (US 329B)]

Hello,

Thanks for your interest in using ECCO products.

I’d recommend that you first try ECCO V4r4. V4r4 is the latest release of ECCI central estimate that  has a nominal 1-degree horizontal resolution and covers the period 1992-2017. It has daily- and monthly-mean OBP available. See more details at https://ecco-group.org/products-ECCO-V4r4.htm. We also have a new product, V4r5, covering 1992-2019 that is to be officially released soon. Some of V4r5’s core variables, including OBP, are already available at https://ecco.jpl.nasa.gov/drive/files/Version4/Release5/.

You can also consider using ECCO2 (run id Cube 92) that has a higher resolution (0.25-degree) and covers the time period between 1992 and March 2022. ECCO-KFS is not recommended, as it has not been actively developed for some time and is currently not being extended in time.

Best,
Ou Wang

Hi, support group,

I would like to collect Ocean Bottom Pressure (OBP) data for modelling crustal deformation, thanks to the various datasets you provide.

But the wide variety of products on the site (https://urldefense.us/v3/__https://ecco-group.org/products.htm__;!!PvBDto6Hs4WbVuu7!M_mcxvkKrS1u9uRFaoZ-c1r7vhK9Udi2FbS3ematgN9ENVvXLWu4AGf0ncOqbIxAuPMKIbuZH0-qo91uOay5Eg$ ) confuses me. ECCOv4r4 is the most recent version, but only ECCO2 and ECCO-KFS have been updated to now. So I wonder what the main differences, especially for OBP, between these three. Are there differences in time resolution, method accuracy, or other aspects? In addition, which dataset is more recommended for modelling pressure-induced deformation?

Thank you very much!

Best regards,

Wenlan Fan
