Converts mole fraction to partial pressure of CO2James Orr
We also perform similar analysis of the first derivative of CO2 mole fraction, ΔtCO2, that is a crude proxy for changes in CO2 flux. Using numerical experiments, we quantify the aliasing error associated with independently identifying trends in phase and peak uptake and release to be 10???25...
Estimating uncertainty of the WMO mole fraction scale for carbon dioxide in air [1] The current WMO CO2 Mole Fraction Scale consists of a set of 15 CO2-in-air primary standard calibration gases ranging in CO2 mole fraction from 250 to ... LZ Cong,PP Tans - 《Journal of Geophysical Resear...

(GEOS-Chem).TheTan-Tracker system used the simulated CO_2 concentrations and fluxes as a background field and assimilated the GOSAT column average dry-air mole fraction of CO_2(X_(CO_2)) data to optimize CO_2 concentrations and CFs in the same assimilation window.Monthly simulated X_(CO...
We have developed an ensemble Kalman Filter (EnKF) to estimate 8-day regional surface fluxes of CO2 from space-borne CO2 dry-air mole fraction observations (XCO2) and evaluate the approach using a series of synthetic experiments, in preparation for data from the NASA Orbiting Carbon Observatory...
mole fractionundersaturatedContinuous monitoring of oceanic and atmospheric CO2 during periods of 8 to 12 days in two particular locations of the tropical Atlantic was carried out during June-August 1986. At the first location (convergence zone; about 5°N, 20°W), the ocean surface was ...
(see Figure 6). Although this represents just a tiny fraction of 1 mole of water (~18 g), it contains more water molecules than can be clearly imagined. If the molecules were distributed equally among the roughly seven billion people on earth, each person would receive more than 100 ...
Atmospheric levels of CO2 are currently 395 ppm (dry air mole fraction measured at Mauna Loa, Hawaii), their highest concentration in 420,000 years. Forests play a major role in the global carbon (C) cycle by taking up inorganic C as CO2... K Hale 被引量: 2发表: 2015年 Analysis of...
