Annual updates to the model-observation comparisons for 2023 are now complete.

There were a few minor changes this year: Old versions of the NOAA STAR TMT data are no longer available and so they’ve been removed. All NOAA NCEI surface temperature lines are now using v5.1. New comparisons for SST and TMT-Corrected were added mid-way through last year and have also now been updated.
