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

Trouble with Trancendental Numbers

The title of this post was supposed to be┬áThe Temperature and Altitude of Radiation to Space. With a bit of luck and perseverance that post will happen, but we’ve had so much trouble, the trouble itself seems to warrant a … Continue reading

Berkeley Earth Absolute Temperature and the Remarkable Closeness of TMAX Lows and TMIN Highs

Bob Tisdale recently did a series of posts exploring the differences between using absolute temperature and temperature anomaly to understand the recent temperature evolution of our planet. Bob was interested in the extracted TMAX highs and TMIN lows, and showed … Continue reading

Aerobic and Anaerobic Metabolism: A Symmetry

The symmetry between aerobic carbohydrate respiration and photosynthesis is widely appreciated. In the presence of Oxygen, many living things (including photosynthesizers) burn carbohydrates, producing useful energy and CO2. Photosynthesizing creatures, using the energy of sunlight, manufacture carbohydrates from CO2 for … Continue reading

Cold Smoke

Santa Rosa is comfortably away from the fires this year. Last year’s baptism cleaned out the tinder around here. Yet the Camp Fire has given us the peculiar combination of dense smoke and hard frost. A lot of the particles … Continue reading
