This is awesome, and if 0.1 degree resolution doesn't exist, I think 0.25 will work! Thanks for your answer; I'll leave the question open for a couple more days, and then mark as best!

Do you mean the average over the entire year?  You could calculate this from ERA-5 data, but 0.1 degree may be a little too high resolution to ask for; that would be in the order of 10 km.  Will 0.25° do?  I don't know if there are regional models for the continents you ask for, as most regional models are centered at the richer areas of the world.

@ebv even if some of the modeling behind could be similarly, weather forecasts and global reanalyses are two different products (https://www.ecmwf.int/en/research/climate-reanalysis). Climate reanalyses use high resolution models (that could be the same as the ones used in the forecasts) to reproduce recent climate in accordance to the observations from the meteorological stations on the ground. The resolution of the models could be much finer than 0.1 degrees, but the outputted data at global level at that resolution would be enormous and therefore these datasets very expensive to manage

Ocean sea surface temperature is available from GOFS 3.1 (https://www.hycom.org/dataserver/gofs-3pt1/analysis). The most recent configuration is 0.08 deg in longitude and 0.04 deg in latitude.

The most important reanalysis datasets covering until present time (I'm excluding the others that stop some years before present time) currently available are:

1. [ERA5](https://www.ecmwf.int/en/forecasts/datasets/reanalysis-datasets/era5) by [ECWMF](https://www.ecmwf.int/): 1979-present (soon 1950-present), temporal resolution of 1 hour and spatial resolution quarter degree (0.25 x 0.25);
2. [CRU](http://www.cru.uea.ac.uk/data) by the [UEA](http://www.uea.ac.uk/): 1900-present (some variables 1850-present), temporal resolution 3 or 6h, spatial resolution half degree (0.5 x 0.5);
3. [GLDAS](https://disc.gsfc.nasa.gov/datasets?keywords=GLDAS) by [NASA](https://ldas.gsfc.nasa.gov/gldas): 1948-present, temporal resolution 3 or 6h, spatial resolution quarter degree (0.25 x 0.25).
4. [ERA5-LAND](https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-land?tab=overview) by ECMWF: 1981-present, temporal resolution of 1 hour and spatial resolution 0.1°x0.1°, global coverage, but only land-covered surface.
