Welcome to the Health and Air Quality User Forum! This forum is intended to support broad data needs in health and air quality, with a focus in satellite data. Our goal is to support users in the process of determining what data product is ideal for their needs in a welcoming and user-oriented...

There are three links below that may be helpful for what you are looking for. Let us know which one worked the best! European Environment Agency - Air Quality e-Reporting Copernicus European Environment Agency - AirBase

Navy’s Model: offers an aerosol forecast that includes both dust and smoke in various regions, including the Gulf of Mexico and the ocean. NOAA’s operational AQ model: offers near real time surface smoke and dust over the continental United States, and part of the Gulf of Mexico, the Atlantic...

Some more tools to explore include NASA Worldview, NASA Firms, the Disasters Portal, NASA Air Quality Forecasts, and NOAA JSTAR Mapper.

The HAQAST public meeting in St. Louis, Missouri, will be April 18th and 19th, 2023. Check out the link below for more information. https://haqast.org/haqast-missouri/

Satellite data increases spatial coverage. In some areas, monitors are sparsely located so satellites can be used to fill the gaps in the data left from the monitors. Additionally, remote sensing provides globally consistent observations.

Despite public accessibility and near-real-time availability, widespread application of satellite data still presents technical barriers. Satellite data, particularly in their unprocessed form, are large and require significant computational resources to store and parse. Thus, visualizing and...

One key difference between satellite air pollution data and ground monitors is that while monitors directly measure air pollutant concentrations at the surface, satellite instruments take measurements of the entire atmospheric column. Thus, satellite data is not a direct measure of air pollution...

Yes, in some situations satellite data is used by itself. Some examples would be mapping smoke plumes, a dust storm, or for meteorological purposes. However, it can also be coupled with other data products such as ground based measurements and models.
