Inverse hockey stick in the lower troposphere – real or not?

Bishop Hill via correspondent Gras Albert noted this event early today: I looked through the entire satellite record, and couldn’t find any similar event. That meant it was either unique, or indicative of a technology failure like we witnessed with NSIDC when one of their sensor channels gave out. I asked Dr. Roy Spencer if…

UAH global Temperature for December – no change

UAH Global Temperature Update for Dec. 2011: +0.13 deg. C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly for December, 2011 remained about the same November, +0.13 deg. C (click on the image for the full-size version): The 3rd order polynomial fit to the data (courtesy of Excel) is for entertainment purposes…

NASA checking TERRA/AQUA satellite observations against citizen observer ground reports

S.D. Maley writes of an interesting and somewhat surprising NASA program trying to fill in observation gaps where satellites are getting cloud cover wrong: NASA is in the process [1] of checking two satellites [2] against ground observer reports. Student groups seem to be the primary focus, but adults can participate via: http://science-edu.larc.nasa.gov/SCOOL/Rover/ The Database…

UAH global temperature – holding steady in November

UAH Global Temperature Update for Nov. 2011: +0.12 deg. C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly for November, 2011 remained about the same as last month, at +0.12 deg. C (click on the image for the full-size version): The 3rd order polynomial fit to the data (courtesy of Excel) is…

Why the UAH global temperature is late

November Global Temperature Update Delayed By Dr. Roy Spencer There has been a delay in our monthly processing of global temperature data from AMSU. An undersea telecommunications cable used to transmit about half of the huge volume of data coming from the Aqua satellite was cut in late November off the coast of the Netherlands,…
