Evaluation of historic papers on CO2: Callendar – Keeling etc.

Callendar (1958) “On the amount of CO2 in the Atmosphere”

See Callendars rejection of inaccurate values concerning free air p. 244 a) and d):

CO2 values are inaccurate when: ” period mean values 10% or more different from general average of time and region” or

“by measurements intended for special purpose such as biological, soil air, atmospheric pollution etc.”

Callendar (1940) “Variations of the Amount of Carbon Dioxide in Different Air Currents” (*.doc)

Keeling: 1986 Reassessment of late 19th Century atmospheric carbon dioxide variations…..(zip)

See Keelings discussion of low values of Reiset and Muentz p. 88

Keeling p 91: “Muentz & Aubin rivaled Reiset at professing to be among the most careful of the 19th century investigators of CO2” He had not investigated many others!

Keeling p. 103: “…Reiset…and his results show no abnormally low concentrations suggestive of incomplete absorption.” Wrong: He used H2SO4 for drying the air before absorption, and H2SO4 absorbs a considerable fraction of CO2, so his values are systematicly too low. Keeling was chemist! ( See Reisets article of 1880: Compt. Rend. 90, 1880, p. 1145) above.
