It contains information on concentrations of carbon dioxide and other radioactively active gases in the atmosphere; the role of the terrestrial biosphere and the oceans in the biogeochemical cycles of greenhouse gases; emissions of carbon dioxide to the atmosphere; long-term climate trends; the effects of elevated carbon dioxide on vegetation; and the vulnerability of coastal areas to rising sea level.
Air Quality Forecast Guidance Maps
Twice per day NOAA's National Weather Services publishes digital maps that show national forecasts for ozone, smoke, and dust. Ozone is shown as 1-hour and 8-hour concentrations. Official Air Quality point forecasts, issued by state and local air quality forecasters, along with additional information on air quality can be found under EPA's AIRNow site. Surface and column-averaged concentrations of predicted smoke for large fires are displayed as 1-hour averages, updated each day.
Smoke Forecasting System
The NOAA Smoke Forecasting System integrates satellite information on the location of wildfires with weather data inputs from the North American Mesoscale model and smoke dispersion simulations. The result is a daily prediction of smoke transport and concentration 48 hours into the future. The model also incorporates U.S. Forest Service estimates for wildfire smoke emissions based on vegetation cover. This system is intended as guidance for air quality forecasters and the public for fine particulate matter emitted from large wildfires and agricultural burning, which can elevate concentrations of fine particles to unhealthy levels. Particle pollution can be particularly hazardous for people with asthma and other respiratory illneses.
Air Stagnation Index
Atmospheric pollution manifests itself in many ways, ranging from reduced visibility to dangerous respiratory problems and discomfort. Atmospheric pollution can be gaseous (e.g. ozone, sulfur dioxide, nitrogen oxides) and/or particulate (e.g. soot, dust). The degree of pollution is dependent on a number of factors: source, transport from source, and build up over time through air stagnation. The stagnation index maps show where in the United States air has stagnated, leading to potential impacts on human and environmental health.
