Carbon Monoxide (CO) is a poisonous, odorless and colorless gas.

Alone it can impact the respiratory system, but it also contributes to the formation of other pollutants including ground-level ozone and particulates, which also carry adverse health effects.
Air quality forecasters use near real-time (Aerosols absorb and scatter incoming sunlight, which reduces visibility and increases the optical depth. Aerosols also have an effect on the weather and climate by cooling or warming the earth, helping or preventing clouds from forming. CO is a trace gas produced by methane oxidation, fossil fuel consumption (emitted from factories and cars) and biomass burning (from forest fires and agricultural burning). Chemistry-climate model output would be combined from satellite data from a fleet of geostationary satellites.“We think the new perspective made possible by geostationary sensors would provide data that is useful for everyday air quality forecasting, as well as for early warnings about extreme events, like the effects of wildfires,” said Helen Worden, NCAR scientist and member of the research team, according to the MOPITT provides one to two measurements over a given location per day.
Air quality forecasters use near real-time data from NASA's Land, Atmosphere Near real-time Capability for EOS to improve some local and national air quality forecasts. Welcome to the NASA LaRC Airborne Science Data for Atmospheric Composition. Anyone living in a major U.S. city for the past decade may have noticed a change in the air.

MultiscaleAir Quality Models Abstract • Air quality modelers represent an important group of NASA Earth science data users. The FAA-required EDMS is a model designed to assess the air quality impacts at airports.
The current efforts focus on improving test predictions of fine particulate matter (PM2.5) from CMAQ. Aerosols scatter and absorb incoming sunlight, which reduces visibility. Car emissions also continue to be a pollution source, but are now contributing a smaller proportion of total emissions.One thing is certain, that viewing from above gives scientists the opportunity to see the whole United States, instead of relying on site specific ground based measurements.MISR with it’s multiple angled views of the Tinder fire, makes it uniquely capable of tracking the plume height and direction of one of the first fires of the 2018 season in the United States.
The fire started on April 27th, 2018 from an abandoned campsite and quickly spread through, Cococino National Forest in, eastern Arizona. KORUS-AQ serves as a model for international collaboration as Korean and U.S. scientists would cooperate on all aspects of air quality research.
One of the most prevalent issues with air quality monitoring is the lack of distribution of sampling sites that gather data regarding particulate matter (PM) concentrations in the surrounding environment. (G and H) same as A–F, but for MOPITT surface layer CO measurements with unit ppb (parts per billion).Researchers concluded that emissions, especially for nitrogen dioxide, have not decreased as thought because of vehicle and industrial emissions. Fire is often thought of as a menace and detriment to life, but in some ecosystems it is necessary to maintain the equilibrium, for example, some plants only release seeds under high temperatures that can only be achieved by fire, fires can also clear undergrowth and brush to help restore forests to good health, humans use fire in slash and burn agriculture, to clear away last year’s crop stubble and provide nutrients for the soil and to clear areas for pasture.
Accurate early warnings of poor air quality are useful because they give people the option to reduce their risk of exposure to poor air by limiting outdoor activity at these times. The dashboard is a user-friendly tool to track changes in air and water quality, climate change, economic activity, and agriculture. Air quality models are designed to simulate the transport, reaction, CO hinders the atmosphere’s natural ability to rid itself of harmful pollutants. Check out the current set of printable models. The second area targeted is in improving chemical transboundary and initial conditions in the air quality model.
