The Hadley Center collects data from the 4 corners of the earth soundings in the data base HadHAT since 1958, 20 years before the satellite measurements of atmospheric temperature. The data is updated in December 2009 and relate to the temperature anomalies in 9 levels of the atmosphere, from 850 to 30hpa.
In this post looks at the data overall monthly smoothed over 7 months with Gaussian method.
In the opening, since it concerns the heights of 850, 700 and 500 hPa shows a trend rather synchronously at 3 heights selected conandamento very similar to that of GW on the surface. You notice a sharp drop from 1958 to 63 and then swinging period but "sub-media" and then a tremendous leap that raises the anomalies of more than half infrequently from 1976 to 1980-1. Climb higher with the various "waves".
We have often seen the data of the lower troposphere satellite, this time to support them, UAH, data HadHAT to 700hpa, averaged together to eliminate differences in the average benchmark, more data rounded to 7 months:
As you can see the data and UAH Hadhat are very well aligned except in a couple of times I tried.
We see now the data of middle and upper troposphere, 500, 300 and 200hpa, they've joined the data of the mean tropospheric RSS:
As seen in the graph of the data 200hpa are very different from those at 500 and 300hpa, aligned with each other enough, this also depends on the fact that 200hpa are in the troposphere in tropical latitudes and medie but end up in the stratosphere at high latitudes (north and south). However, this difference is increasing dramatically after the eruption of Mount Pinatubo cheporta a strong cooling in the stratosphere and thus a marked difference between the anomalies at 200 compared to 300hpa. see the trend of differences between the two units, I've marked the volcanoes and the "average" of each period:
What happened in the stratosphere we see with the data of the stratosphere, 150 and 100, very low stratosphere.
... And the data of middle and upper stratosphere:
In both graphs I put the data of the lower troposphere UAH. Very evident declinetemperatures in the stratosphere after the Pinatubo, more and more evident with the height (the smaller the influence 150hpa, high to 50 and 30hpa).
And above this, the fact that after the eruption dell'Agung although there are a sharp drop in temperatures in the stratosphere into the troposphere the differences between 300 and 200hpa decrease whereas increase after El Chichon and Pinatubo especially. The secrets of the last wave of GW are written in these graphs.
