6. Spaceborne measurements of CO2 can be derived from instruments that measure in near infrared wavelengths (such as OCO-2,  OCO-3, and GOSAT) and from instruments that measure in thermal infrared wavelengths (such as TES, AIRS, and CrIS). Which of the statements below is true? (Pick 1)*5 pointsA. Near infrared spectral measurements can provide sensitivity to variations in CO2 throughout the atmospheric column and can be used in the estimation of sources and sinks.B. Measurements of CO2 spectral bands in the near infrared and thermal infrared measurements of CO2 provide equivalent vertical sensitivity.C. Near infrared spectral measurements can provide information on the fine-scale vertical structure of the shape of the profile of atmospheric CO2.

Which of the following is TRUE about CO2 in the atmosphere?a.A large percentage of CO2 in the atmosphere comes from natural carbon cycleb.Deforestation leads to more CO2 in the atmospherec.CO2 can only come from natural sourcesd.CO2 in the atmosphere only comes from anthropogenic sources

When referring to the bicarbonate buffering system, which of the following statements is most true for carbon dioxide? When referring to the bicarbonate buffering system, which of the following statements is most true for carbon dioxide? CO2 directly buffers blood by binding to HCO3- Decreased CO2 levels can decrease blood pH. Increased CO2 levels can decrease blood pH. CO2 levels do not influence blood pH.
