Most of the NCEP data for March global surface temperature is in, and despite some cooling at the end, it still looks to be a little warmer than February. Probably less than May 2014, but higher than any other month in 2014 (or 2015). I'd expect this to be reflected in surface temps.
I've fixed a bug where in the daily NCEP table, dates were written one day ahead (on Australian time). Dates on the maps were correct.
