Air Quality. Trapped pollution is evident as a “brownish” color due to elevated concentrations of nitrogen dioxide very near to the ground which is emitted from cars and other combustion sources. Baltimore elevated pollution levels in the summer, on the other hand, are often attributed to heightened ozone levels that increase with rising temperatures and more direct sunlight. That’s becauseinversions act as a lid and trap whatever is emitted between them and the ground. (2019). Stopping upwind air pollution. BreezoMeter’s Air Quality, Pollen, and Weather include current conditions and forecasts.
While Baltimore has met federal levels for 24-hour and annual PM2.5 since 2008, 2019 saw an uptick of particulate pollution. On Wednesday an inflow of tropical moisture along with the approach of a frontal boundary from the west will lead to moderate to heavy rain across the area. Read the air pollution in Baltimore, Maryland with AirVisual. Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion. Baltimore Air Quality Index (AQI) is now Good. Ozone pollution tends to be the worst during daylight hours and on weekdays when traffic is relatively heavy. Washington DC air quality likely fares better than Baltimore's as a result of less industry and a greater share of electric vehicles on the road.4 Such a contrast provides a possible roadmap for Baltimore to obtain air quality compliance. The MDE continues its legal fight to hold these out of state polluters accountable. Since at least 1996, Baltimore has exceeded the federal limit on unhealthy ozone days.1 Most recently, in the period from 2016 to 2018, the city experienced a weighted average of 14.2 unhealthy ozone days, several times above the federal limit of 3.2. In addition, the Program collaborates with local universities to conduct special atmospheric monitoring research to better characterize aloft and surface atmospheric pollutant concentrations. Fine particulate matter, or PM2.5, is another pollutant of concern in the city. The MDE identified 19 over-polluting power plants in the five-state area and petitioned the US Environmental Protection Agency (EPA) in November 2016 that they be required to turn on pollution controls in general compliance with, or to the precedent of, Maryland law. High AQI levels represent the riskiest air quality overall, which in Baltimore tends to occur in November, December, and January. Once connected, air pollution levels are reported instantaneously and in real-time on our maps Ozone is created when sunlight and heat trigger chemical reactions between precursor pollutants in the air. Still, Baltimore has never met federal attainment levels for ozone pollution. The GAIA air quality monitoring stations are using high-tech laser particle sensors to measure in real-time PM2.5 pollution, which is one of the most harmful air pollutants.

To report an environmental emergency, see Emergency Numbers. February, July, August, November, and December of 2019 all experienced PM2.5 levels categorized as US AQI “moderate.” In previous years, such as in 2018 and 2017, no months fell into this higher AQI category.
It illustrates changing wind direction during the day due to heating differences between the water and land. Interested in hourly forecast? Members of sensitive groups may experience health effects. View our real-time, 3D animated air pollution map, See the most polluted cities around the world, How to set up a public air quality monitoring station. An estimate from the Maryland Department of the Environment (MDE) found that roughly two-thirds, or 70 percent, of Baltimore smog may be attributable to upwind states.3 Namely, Baltimore’s ozone problem is largely the result of power plant and vehicle emissions carried over from Pennsylvania, West Virginia, Indiana, Ohio, and Kentucky.

Health alert: everyone may experience more serious health effects, Everyone should avoid all outdoor exertion. Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution. Trump administration's relaxed EPA regulations, Close your windows to avoid dirty outdoor air, Sensitive groups should reduce outdoor exercise.
After a lengthy legal battle, the EPA denied its role in protecting Maryland from transboundary air pollution. These trends reveal pollution mitigation efforts by Maryland and the federal government – namely, increasingly stringent regulations on industry and vehicles as well as new technologies for more efficient energy. Fine particulates will begin to wash out, leading to the return of Good air quality across the state. While many of these states have regulations roughly in line with Maryland’s, enforcement isn’t as rigorous, resulting in over polluting. Similar increases in PM2.5 and ozone in 2019 (and often since 2017) have been observed in numerous cities across the US. This decrease in temperature is what allows snow on mountain tops while it may be sweltering at the mountain base. Baltimore air pollution levels result from city sources, including building heating, traffic, and industry as well as out-of-city and out-of-state sources carried over by wind. The general public is not likely to be affected. Get real-time, historical and forecast PM2.5 and weather data.
Without sunlight, inversions strengthen. The Ambient Air Monitoring Program measures ground-level concentrations of criteria pollutants and air toxics, along with surface and aloft meteorological parameters. Pollen and Air Quality forecast for Baltimore, MD with air quality index, pollutants, pollen count and pollution map from Weather Underground. This is particularly evident with pollution and most apparent during the winter months when inversions are typically the strongest.
