This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS through February 2015 and HADCRUT4 and NCDC through January 2015—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through February 2015.
For discussions of the annual GISS and NCDC data for 2014, see the posts:

GISS LOTI surface data, and the two lower troposphere temperature datasets are for the most recent month. The HADCRUT4 and NCDC data lag one month.
This post contains graphs of running trends in global surface temperature anomalies for periods of 14+ and 17+ years using GISS global (land+ocean) surface temperature data. They…
