Kiehl & Trenberth and the Atmospheric Window 2 Feb 2013 | 06:06 am
Many curiosity values in atmospheric physics take on new life in the blogosphere. One of them is the value in Kiehl & Trenberth 1997 for the “atmospheric window” flux: Figure 1 Here is the update in 2...
Visualizing Atmospheric Radiation – Part Twelve – Heating Rates 30 Jan 2013 | 01:27 pm
In Part Two we covered quite a bit of ground. At the end we looked at the first calculation of heating rates. The values calculated were a little different in magnitude from results in a textbook, but...
Visualizing Atmospheric Radiation – Part Eleven – Stratospheric Cooling 27 Jan 2013 | 06:08 pm
Understanding atmospheric radiation is not so simple. But now we have a line by line model of absorption and emission of radiation in the atmosphere we can do some “experiments”. See Part Two and Part...
Visualizing Atmospheric Radiation – Part Ten – “Back Radiation” 23 Jan 2013 | 02:39 pm
We have mostly looked at the upward spectra at the top of atmosphere (TOA) as various conditions are changed. There’s a good reason for this focus – the outgoing longwave radiation (OLR) determines ho...
Visualizing Atmospheric Radiation – Part Nine – Reaching Equilibrium 20 Jan 2013 | 12:34 pm
In the series so far we have seen how radiation interacts with the atmosphere for a given surface/atmospheric condition. That is, if the temperature is say 288K (15°C) and the atmospheric temperature ...
Visualizing Atmospheric Radiation – Part Eight – CO2 Under Pressure 15 Jan 2013 | 04:29 am
In Part Seven we looked at progressively wider wavelength ranges to see where doubling of CO2 had an impact. We also compared the top layer of the atmosphere (in that model) with the bottom layer – ag...
Visualizing Atmospheric Radiation – Part Seven – CO2 increases 13 Jan 2013 | 09:59 am
I created some simulations of different CO2 concentrations using the atmospheric radiation model described (briefly) in Part Two and in detail in Visualizing Atmospheric Radiation – Part Five – The Co...
Visualizing Atmospheric Radiation – Part Six – Technical on Line Shapes 12 Jan 2013 | 11:55 am
This is a technical thread – not really “visualization” at all, just part of the series – looking for comment and verification. Interested people can read a little about line shapes in Atmospheric Ra...
Visualizing Atmospheric Radiation – Part Five – The Code 10 Jan 2013 | 06:02 am
The MATLAB program for the previous articles in this series is attached as a .doc file. It’s not a .doc, it is a text file (but WordPress doesn’t give the option of .txt uploads), so save as, rename t...
Visualizing Atmospheric Radiation – Part Four – Water Vapor 9 Jan 2013 | 01:43 pm
We’ve looked, via the model, at how radiation travels through, and interacts with, the atmosphere. But this has been for one set of atmospheric conditions which are listed in Part Two. Water vapor is ...
