I want to make this project as similar as possible to this graph: https://climatereanalyzer.org/clim/sst_daily/

It's not clear if that is possible with only the Argo datasets from https://github.com/euroargodev/argopy

@gmaze do you have suggestions?

Hi @mikestaub argopy can surely help in retrieving near-surface temperature data from Argo but:

this is not exactly SST, I guess top 1m at best (I see in your code you used 20db)

and

data will be sparse and it won't be trivial to get a correct 60N/60S global mean

In https://github.com/mikestaub/sea-surface-temperature-analysis/blob/3cb90c4d04345ecda5418f54429c350ec2ffa825/plot-argo-data.py#L60 you take the daily global mean without considering the un-even spatial distribution of the data, for a more reliable average, you may consider to remove profiles "too" close to each others. Another intermediate solution, more reliable and statistically correct, would be to bin the data by 1x1, 2x2 or 3x3 degrees before taking a latitude weighted mean
