March 2016 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update

Posted on April 15, 2016 by Bob Tisdale

This post provides an update of the values for the three primary suppliers of global land+ocean surface temperature reconstructions—GISS through March 2016 and HADCRUT4 and NCEI (formerly NCDC) through February 2016—and of the two suppliers of satellite-based lower troposphere temperature … Continue reading →

February 2016 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update

Posted on March 12, 2016 by Bob Tisdale

UPDATE (April 15, 2016): I discovered an error in the model-data comparison and model-data difference graphs (Figures 10 and 11) that impacted only the January 2016 values. The error has been corrected. # # # We recently discussed the February … Continue reading →

Meteorological Year (December to November) Global Temperature Product Comparison through 2015

Posted on January 8, 2016 by Bob Tisdale

It should come as no surprise that surface temperature products are showing record highs for the meteorological year of December 2014 to November 2015 and that lower troposphere temperature products are not.

November 2015 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly & Model-Data Difference Update.

Posted on December 14, 2015 by Bob Tisdale

As you’ll recall from last month’s update, the GISS Land-Ocean Temperature Index jumped upwards more than 0.2 deg C from September to October 2014, assumedly a response to the El Niño.  The NOAA/NCEI and UKMO HADCRUT4 data lag by one … Continue reading →
