Now 2017 has finished we publish all climate data reports for that year as soon as the data comes in. 2016 was a record in all series, 2017 probably will be in the top 3 in all.
First one at the top is the ERA Interim from the European Copernicus project. In this dataset 2017 takes a second place.
Next one is the satellite data from REMSS. Also a second place for 2017 in this dataset.
Third one is the, still controversial, satellite data set from UAH. Here 2017 takes up a third place.
