UAH Satellite series

Why do I now use the UAH temperature set as my main point of interest?

Version 6.0 of the UAH Temperature Dataset Released: New LT Trend = +0.11 C/decade

“After three years of work, we have (hopefully) finished our Version 6.0 reanalysis of the global MSU/AMSU data. Many procedures have been modified or entirely reworked, and most of the software has been rewritten from scratch. (Please, before you ask a question, read the following to see if your question has already been answered.)

The MSU and AMSU instruments measure the thermal microwave emission from atmospheric oxygen in the 50-60 GHz oxygen absorption complex, and the resulting calibrated brightness temperatures (Tb) are nearly equivalent to thermometric temperature, specifically a vertically-weighted average of atmospheric temperature with the vertical weighting represented by “weighting functions”.”

Because hard working scientists who first introduced the methodology produce it. Ones that are continuously trying to improve those data capture methods so that even more accurate results can be achieved. That’s why.
