Packet 4: Bonus 22
The FLUXNET data set partitions this molecule’s concentration into gross primary production and ecosystem respiration components. For 10 points each:
[10e] What gas, whose concentration recently reached 400 parts per million, is the target of namesake “capture and storage” efforts to reduce emissions?
ANSWER: carbon dioxide [or CO2]
[10h] FLUXNET is a global network of sites that measure greenhouse gas exchange between the atmosphere and ecosystems using this technique. It uses a sonic anemometer and atmospheric sensors to calculate transport based on fluctuations in vertical wind.
ANSWER: eddy covariance [or eddy correlation or eddy flux]
[10m] FLUXNET data can also be used to measure the density of these structures to estimate primary productivity. NDVI data can be used to determine the extent of these structures in their namesake “area index.”
ANSWER: leaves [or leaf; accept leaf area index]
