Updated March 15, 2018 07:10:36The measurement of CO2 is the most commonly used measurement of atmospheric CO2 concentrations.
It is commonly used to gauge the extent of the problem of global warming.
It has been used to measure CO2 in the atmosphere for decades, and the measurement has been a benchmark for climate scientists for many decades.
In a paper published in the journal Science, the researchers examined data collected by the CO2 sensor aboard the International Space Station, or ISS, from 2008 to 2013.
The researchers compared this data to the measured CO2 measurements by the two different instruments aboard the ISS.
The data was collected by two different spacecraft, one that measured CO02 on the surface of the Earth, and another that measured it at high altitude on the ISS, and averaged the two.
They compared the results of this analysis to measurements made by NASA’s Deep Space Climate Observatory (DSCOVR), which monitors CO2 at high altitudes.
The authors found that the measurements by both instruments were significantly different, and that CO2 measured at high-altitude sites is much more variable than that measured at the ISS site.
The two different measurements were consistent with the findings of the paper, and they concluded that the differences in CO2 from the ISS were due to variations in atmospheric humidity.
According to the authors, the reason that the two instruments did not measure CO02 at high levels at high elevations is because of differences in atmospheric circulation patterns, not because of the ISS sensor.
The results of the study indicate that the data was more reliable at low elevations, as well.
“The results from the COH-16 measurement are consistent with observations from both instruments at higher altitudes, but not with measurements at higher elevations,” the authors wrote.
“Therefore, the measurements from the instruments are not a reliable indicator of COH levels.”
While this finding was surprising, it is not entirely unexpected.
Atmospheric humidity is a variable, and changes in atmospheric conditions are a common process for measuring atmospheric CO02 levels.
This is especially true in the tropics where air conditions are usually warmer and the temperature is generally higher, but CO2 can also be detected from lower altitudes in the Pacific Ocean.
“We think that the higher CO2 concentration that is measured in the upper atmosphere is probably due to changes in humidity, which are more variable in this tropics than in the equatorial region,” lead author Dr. Mark Sargent said in a statement.
The findings of this study are consistent to previous research, and indicate that it is possible to use the ISS measurement to measure atmospheric CO22, the second-highest CO2 level in the Earth’s atmosphere.
While the findings may not be of much use to anyone concerned about global warming, the research does help to further understand how CO2, in particular CO2s with a half-life of 1.8 to 3 years, is distributed throughout the atmosphere.
“This study indicates that, as expected, the observed CO2 distribution is more variable on Earth than previously expected, which supports the importance of measuring CO2 as a proxy for atmospheric CO21 levels,” the paper said.
