I downloaded the new temperature series in November 2019 1. They have temperatures up to and including October 2019. I downloaded the old temperature series in the end of 2014 and in the beginning of 2015. The old UAH and RSS satellite temperature series for the lower troposphere (TLT) have temperatures up to and including September 2014. The old surface temperature series GISTEMP, NOAA Global, HadCRUT4 and BEST have temperatures up to and including December 2014.
