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.
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.
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.
The National Weather Service provides weather, water, and climate data, forecasts and warnings for the protection of life and property and enhancement of the national economy. These products include forecast and warnings of environmental events that can impact human health, such as excessive heat, flooding, severe cold, and more.
The vegetation health products can be used as proxy data for monitoring vegetation health, drought, soil saturation, moisture and thermal conditions, fire risk, greenness of vegetation cover, vegetation fraction, leave area index, start/end of the growing season, crop and pasture productivity, teleconnection with ENSO, desertification, mosquito-borne diseases, invasive species, ecological resources, land degradation, etc.
Compiles global hourly and synoptic observations from numerous sources into a single common ASCII format and common data model. Station data available worldwide with some data as far back as 1901. Over 11,000 stations are currently "active" and updated daily. Includes many parameters such as wind speed & direction, wind gust, temperature, dew point, cloud data, sea level pressure, altimeter setting, station pressure, present weather, visibility, precipitation amounts for various time periods, snow depth, and more.
These data tables of meteorological elements outline the climatic conditions at major weather observing stations in all 50 states, Puerto Rico, and Pacific Islands. The data are from observing sites presently in use or include data from former sites that are comparable in exposure. Stations having less than 3 years of data for the current operating site are omitted from the tables of observed data.
