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…
First some news on the status of the WUWT Sea Ice Page. The JAXA imagery, which has been DOA ever since the failure of the AMSRE instrument on the AQUA satellite is now operational again. The plot is below: JAXA AMSR-E Sea Ice Extent -15% or greater – click to enlarge In addition, they have…
by John R. Christy and Roy W. Spencer University of Alabama in Huntsville A new paper by Stephen Po-Chedley and Quang Fu (2012) (hereafter PCF) was sent to us at the end of April 2012 in page-proof form as an article to appear soon in the Journal of Atmospheric and Oceanic Technology. The topic of…
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…
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 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…
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,…
Dr. Roy Spencer reports that AMSR-E shut down today, too much torque on the rotating element, and all it needs to keep going is a lube job. AMSR-E Ends 9+ Years of Global Observations by Roy W. Spencer, Ph. D. UPDATE #1: See update at end. The Advanced Microwave Scanning Radiometer for the Earth Observing…
UAH Global Temperature Update for September 2011: +0.29 deg. C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly for September, 2011 retreated a little again, to +0.29 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…
Since its eruption in early June, several NASA satellites have captured images of the ash plume from the eruption of the Chilean Volcano called Puyehue-Cordón Caulle and have tracked it around the world. NASA has collected them in the NASA Goddard FLICKR image gallery that shows the progression of the plume around the southern hemisphere.…
