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

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

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

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

UPDATE: All graphs with UAH lower troposphere temperature data have been updated from beta version 6.4 to 6.5.  Thanks, Nick Stokes.  This means Figure 4 and Figures 6 through 9 have been revised. # # # The GISS Land-Ocean Temperature … Continue reading

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

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.

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

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

As one might expect in response to a strong El Niño, the GISS global Land Ocean Temperature Index jumped 0.24 deg C from September to October 2014, raising its value to more than 1.0 deg C above the reference period temperatures for 1951-1980.

25 Years of Monitoring Global Temperatures from Satellites and an Interview with Christy and Spencer of UAH

It’s been 25 years since Spencer and Christy of the University of Alabama at Huntsvillle published their 1990 paper Precise Monitoring of Global Temperature Trends from Satellites.  The abstract reads (my boldface): Passive microwave radiometry from satellites provides more precise … Continue reading

October 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly & Model-Data Difference Update

I’ve added a graph of the difference between the observed global temperature anomalies (GISS LOTI) and the climate model simulations of that metric by the models stored in the CMIP5 archive (used by the IPCC for their 5th Assessment Report).  … Continue reading
