Tristanc you used different altitudes from the ONE and only RSS dataset in C10,25 etc

Or perhaps even RATPAC in 100mb 70mb, after that you are really drifting away from RSS as a comparison in my opinion. But that is another story that is probably not really a biggie!

So lets ignore what RSS, The IPCC , NOAA WMO. Cannot recall if I have posted ththe WMO yet. But have it here somewhere as another for later)

Your analogy is now equated to me using 5 different GISS monthly temps fr a give city and calling them a dataset!

Yeah bit of a long call that one.

Anyway you used 20 years off data which is 2/3rd of one "climate period" as defined by the World Meteorological Organisation!

The hypocrisy reeks mate

Let's do a little cross-check, shall we?

Here are the RSS C10 and C11 trends, with weighting functions (on the left) peaking at 20km and 25 km respectively. Both well and truly lower stratosphere, but differing from TLS in that contribution from the troposphere is greatly reduced.

Now here are the RATPAC data covering similar altitudes (70 mbar ~ 18.5 km; 50 mbar ~ 20.5 km; 30 mbar ~24 km), split up into tropics and NH/SH extratropics. The trends work out to approximately -0.5 C/decade for the tropics, and -0.33 C/decade for the extratropics - very much in agreement with the shorter-term datasets from RSS.
