The atmosphere has recently been recognized as a major source of energy sustaining life.
Diverse aerobic bacteria oxidize the three most abundant reduced trace gases in the …

Dry deposition of ozone is an important sink of ozone in near‐surface air. When dry
deposition occurs through plant stomata, ozone can injure the plant, altering water and …

Growth in terrestrial gross primary production (GPP)—the amount of carbon dioxide that is
'fixed'into organic material through the photosynthesis of land plants—may provide a …

Anthropogenic mercury emissions are transported through the atmosphere as gaseous
elemental mercury (Hg (0)) before they are deposited to Earth's surface. Strong seasonality …

Terrestrial photosynthesis, or gross primary production (GPP), is the largest carbon flux in
the biosphere, but its global magnitude and spatiotemporal dynamics remain uncertain. The …

Terrestrial ecosystems currently offset one-quarter of anthropogenic carbon dioxide (CO2)
emissions because of a slight imbalance between global terrestrial photosynthesis and …

For the past decade, observations of carbonyl sulfide (OCS or COS) have been investigated
as a proxy for carbon uptake by plants. OCS is destroyed by enzymes that interact with CO 2 …

Remote sensing of sun-induced chlorophyll fluorescence (SIF) has been suggested as a
promising approach for probing changes in global terrestrial gross primary productivity …

The carbon cycle of forest ecosystems plays an important role in cutting down global
environmental pressure, reducing greenhouse effects, and assimilating carbon dioxide …

The eddy covariance (EC) technique is used to measure the net ecosystem exchange (NEE)
of CO2 between ecosystems and the atmosphere, offering a unique opportunity to study …
