Mid Troposphere 2020-2025

The graph of differnt period averages (annual, 3-year, decade and 30-year) is expanded for the six years 2020 to 2025.

How are annual and decadal averages changing over 12 months?

The 2020-25 more detailed graph adds very little to the picture. Once again, it shows that the cooling versus one year earlier may be tailing off - but when is anyone's guess.

Simple Exponential Smoothed

Simple exponential smoothing is a technique to eliminate noise from graphs. A factor is used to determine how much weight is given to recent measurements. The example below shows monthly values and a series of smoother graphs with factors 0.33, 0.12 and 0.06.

All of these smoothed graphs indicate temperatures are currently on a cooling trend. The big question is how long the cooling trend will continue and to what level it will go.
