Map of Field Campaign Areas

Atmosphere/Forest Exchange

We are conducting carbon isotope flux measure- ments and testing of novel flux methods at a poplar plantation in Boardman, OR.

Biosphere-Atmosphere Interactions (CO₂ advection)

In collaboration with Oregon State University, we are investigating CO₂ fluxes into a steep, V-shaped valley within the H.J. Andrews Experimental Forest.

Urban & Industrial Air Pollution

In Houston, TX, field measurements of trace organic gases are used to determine the influence of Houston's petrochemical industry on air quality. How do refineries impact ozone and particulate production?

Biosphere/Atmosphere Interactions

Studies have been conducted in Louisiana, Montana, and Oregon to investigate bark beetle pheromone transport within forest canopies.

Urban Air Quality

On the beach in Malibu, CA with colleagues from UCLA and BMI studying the impact of sea-salt particle chemistry on ozone pollution. Does the interaction of air pollution with sea-salt particles increase ozone concentrations in LA?

Mexico City Air Pollution & the Milagro Experiment

First use of PTR-MS in Mexico City to measure fluxes of organics from an urban area. What are the real world emission rates of hydrocarbons from vehicles?

Biosphere/Atmosphere Interactions

At the Michigan Biological Station in Pellston, MI, long-term volatile organic compound measurements were collected from a forest. How do emissions from natural sources impact atmospheric air quality?

Biosphere/Atmosphere Interactions (CO₂ advection)

We have collaborated with the University of Colorado at the Niwot Ridge Ameriflux site in Colorado to conduct nighttime SF₆ tracer tests to measure the dispersion and transport of gases within nocturnal drainage flows.

Urban Air Quality (MFDOAS measurements)

The MFDOAS instrument, developed for ground-based validation of the Aura Satellite/Ozone Monitoring Instrument, was fielded in prototype form at Pacific Northwest National Laboratory in Richland, WA.

Pacific Northwest (Seattle, Spokane, Lewiston)

In collaboration with the WA Department of Ecology, an Air Toxics Study has been conducted using a mobile unit to collect samples from fixed stations. What levels of hazardous air pollutants do we see in urban areas, and what are their impacts?
