Annual precipitation in the central and southern warm-desert region of North America is distributed climatologically between summer and winter periods with two prominent dry periods between them. We used energy and carbon dioxide (CO2) fluxes from eddy covariance along with standard meteorological and soil moisture measurements …

Recent studies have demonstrated direct methane emission from plant foliage under aerobic conditions, particularly under high ultraviolet (UV) irradiance. We examined the potential importance of this phenomenon in a high-elevation conifer forest using micrometeorological techniques. Vertical profiles of methane and carbon dioxide …

The construction and deployment of a portable trace-gas measurement system (TGaMS) is described. The air-collection system (dubbed HYDRA) collects air samples from 18 different locations and was connected to either one or two LI-COR LI-7000 gas analyzers to measure CO2. An in situ “field calibration” method, that uses four calibration …

Permafrost soils in boreal and Arctic ecosystems store almost twice as much carbon1, 2 as is currently present in the atmosphere

Climate change in high latitudes can lead to permafrost thaw, which in ice-rich soils can result in ground subsidence, or thermokarst. In interior Alaska, we examined seasonal and annual ecosystem CO2exchange using static and automatic chamber measurements in three areas of a moist acidic tundra ecosystem undergoing varying …

Ecosystem level ozone (O3) fluxes during four different years were examined at a subalpine forest site in the Colorado Rocky Mountains. The local mountain–valley wind system and the proximity of the Denver Metropolitan area leads to high summertime ozone episodes on many afternoons. The timing between these episodes and the ecosystem …

Vickers, D., Thomas, C., Law, B. E.
The perturbation timescale-dependences of the CO2 flux and the random flux sampling error are evaluated from eddy-covariance tower observations in the mid-day convective boundary layer over mid-latitude conifer forests. The perturbation timescale is the timescale used in the standard Reynolds decomposition to …
