RISMeasuring and Modeling the Tropospheric Hydroxyl Radical (OH)
Publisher: American Meteorological Society
Abstract: Efforts to measure the tropospheric hydroxyl radical concentration OH, the transient that plays a role in acid deposition formation and cleanses the atmosphere of many pollutants, began 20 years ago. In the past five years ...
The Value of Air Quality Forecasting in the Mid-Atlantic Region
Publisher: American Meteorological Society
Abstract: ir quality forecasts produced by the National Air Quality Forecast Capability (NAQFC), human air quality forecasters, and persistence are evaluated for predictive skill and economic value when used to inform decisions ...
Interpretation of Probabilistic Surface Ozone Forecasts: A Case Study for Philadelphia
Publisher: American Meteorological Society
Probabilistic Forecasting of Surface Ozone with a Novel Statistical Approach
Publisher: American Meteorological Society
Abstract: he recent change in the Environmental Protection Agency?s surface ozone regulation, lowering the surface ozone daily maximum 8-h average (MDA8) exceedance threshold from 75 to 70 ppbv, poses significant challenges to U.S. ...
SHADOZ—A TROPICAL OZONESONDE–RADIOSONDE NETWORK FOR THE ATMOSPHERIC COMMUNITY
Publisher: American Meteorological Society
Abstract: This article describes the Southern Hemisphere Additional Ozonesondes (SHADOZ) network of ozonesonde?radiosonde stations in the southern Tropics and subtropics. SHADOZ was initiated in 1998 by NASA, NOAA, and a team of ...
An Intercomparison of Isentropic Trajectories over the South Atlantic
Publisher: American Meteorological Society
Abstract: The authors have compared isentropic trajectories computed from meteorological fields from different analysis centers. The analysis was performed for the South Atlantic, where a springtime maximum in tropospheric ozone has ...
Tropical Deep Convection and Ozone Formation
Publisher: American Meteorological Society
Abstract: Theoretical studies, aircraft, and space-borne measurements show that deep convection can be an effective conduit for introducing reactive surface pollutants into the free troposphere. The chemical consequences of convective ...
The Ozone Water–Land Environmental Transition Study: An Innovative Strategy for Understanding Chesapeake Bay Pollution Events
Publisher: American Meteorological Society
Abstract: AbstractCoastal regions have historically represented a significant challenge for air quality investigations because of water?land boundary transition characteristics and a paucity of measurements available over water. ...
Ozonesonde Quality Assurance: The JOSIE–SHADOZ (2017) Experience
Publisher: American Meteorological Society
Abstract: The ozonesonde is a small balloon-borne instrument that is attached to a standard radiosonde to measure profiles of ozone from the surface to 35 km with ?100-m vertical resolution. Ozonesonde data constitute a mainstay of ...
Remote Sensing of Tropospheric Pollution from Space
Publisher: American Meteorological Society
Abstract: We review the progress of tropospheric trace gas observations and address the need for additional measurement capabilities as recommended by the National Research Council. Tropospheric measurements show pollution in the ...
