The Temperature and Altitude of Radiation to Space
This post was begun some time ago and we experienced so much trouble replicating the MODTRAN Planck curves that two rambling subsequent posts transpired recounting the misadventure. Here, and here. We eventually concluded that the Planck curves in the MODTRAN … Continue reading

Alalyzing the MODTRAN Planck Curves
This post reports on some progress on resolving our difficulty replicating MODTRAN Planck curves in a prior post. In a personal communication, Dr. David Archer kindly provided the spreadsheet used to produce the MODTRAN curves. The standard wave number Planck … Continue reading

What is Waiting in the Wings?
We recently finished a series of posts on the 2 good greenhouse gas in which we established that all the “earthlight”, the long wave spectra emitted at the temperature of the planet surface is extinguished within about 100 meters of the … Continue reading
The 2 Good Greenhouse Gas II
When show a Carbonist that there is no evidence of CO2 causing significant “global” warming at any scale from deep time to the last 35 years as we did in the last post, they usually look at you funny and say, … Continue reading

Quick and Dirty Irradiance to Radiance
Couldn’t believe it when it turned into a huge mathematical cluster to convert units of irradiance or spectral irradiance as used in models to radiance as used in measurements. Rather than get into the intricacies of spherical harmonics, figuring steradians, and … Continue reading
