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

Guest Post by Bob Tisdale 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 atmospheric temperature information than that obtained from the relatively sparse…
