Data has been measured at Mauna Loa Observatory, Hawaii as it constitutes the longest record of direct carbon dioxide measurements in the atmosphere. CO₂ expressed as a mole fraction in dry air, micromol/mol, abbreviated as ppm. Open this statistic in... Spanish Citation formats Citation...
Aleurites montana exhibits a strongly CO2-dependent photosynthesis which partially explains the observed stimulatory effect of 700 ppm CO2 on growth of the plant. In control plants grown in normal air, photorespiration measured simultaneously with photosynthesis via the uptake of l80 2 in the light, ...
p(air)为气压，p(H2O)为水蒸气的分压。正因为如此，pCO2的数值比xCO2的数值要低一些，多少取决于温...
Rep Power:6 Hi everyone how are you I have study about the CO and AIR interaction so I used ccm to simulate it but I have a problem to builds a graph or to see scalar about the particle per million of the CO. THE PHYSISCAL MODLE THAT I USED : ...
