There's a mixture of trends this month. GISS LOTI went from 0.6°C in January to 0.49°C. Satellite measures were well down, but NOAA rose from 0.54°C to 0.58°C. TempLS showed a small decline.
In other news, the equatorial Pacific jet changed from cold to warm in March. That may be transient.
Update The map is available - I've compared below.
Update. The GISS site had this note:
"2013-03-21: The update this month was postponed a week while we investigated some bad reports from various stations in Mongolia. NCDC eliminated the reports today."
Here is the GISS map for Feb 2013:
And here, with the same scale and color scheme, is the earlier TempLS map using spherical harmonics

Hi Nick
ReplyDeleteI think that your chart of global temp indices for the past few months isn't correctly plotting the data given above it. It seems to get RSS and UAH right but the rest are lower than the numbers in the table.

Simon,
ReplyDeleteThe plots have been shifted to have a common anomaly base (1979-2000). The data in the tables are as they come from the providers, with different anomaly bases. The shift is made to make them directly comparable on a graph.
