The AIRS 13-year random observations and ERA-colocations from our UMBC version of AIRXBCAL are binned per day and analyzed versus time.

I have generated the 13-year linear rates for descending orbit for both the observed and ERA radiances. Note that all calculations and averaging are done in radiance space and then rates converted back to brightness temperature.

Figure 1 shows the average rate over the 40 latitude bins. This is not an area-averaged weight, I will do that later. The fitted 2-σ errors have been adjusted for lag-1 autocorrelation. For window channels we are very close to a 0.01K/year radiance increase.
