McElwain and Chaloner 1995 Paleozoic Paleobotanical Atmospheric CO2 Reconstruction McElwain, J.C.; Chaloner, W.G. McElwain, J.C. Chaloner, W.G. Atmospheric Gas Reconstruction earth science/paleoclimate/climate forcing (carbon dioxide,null,null,dimensionless,null,climate forcing,null,null,N,ratio of past to modern CO2; based on stomatal measurements) earth science/paleoclimate/climate forcing (Global>LATITUDE >LONGITUDE ) Records of changes in solar irradiance, volcanic aerosols, atmospheric trace gases, and other properties thought to influence climate in the past. Parameter keywords describe what was measured in this data set. Additional summary information can be found in the abstracts of papers listed in the data set citations.
