It would most likely be 0.

Good question! Aerosol Optical Depth (AOD) measures the light extinction produced by aerosols in the atmosphere (either by aerosols scattering or absorbing light). AOD tends to be on a scale of about 0-1 where 0 indicates there are no aerosols present (clear sky) and 1 indicates there are dense...

The flowchart currently focuses on the criteria air pollutants but it may be helpful to include more pollutants that are applicable to health and air quality. Does anyone else agree? If yes, what pollutants would you find most beneficial?

Does anyone know of a good resource for learning python? I would like to learn how to work with different file formats and learn more about visualizing data. Thanks in advance!

Using the formaldehyde to nitrogen dioxide ratio from satellite data can provide some insight as to whether a region is NOx sensitive or VOC sensitive for ozone formation. I have linked a publication below by Jin, X et al., 2018 that provides more insight to this topic. Additionally, there is a...

Some commonly used satellites for air quality purposes include Copernicus Sentinel-5 Precursor, Aqua, Terra, Suomi-NPP, and GOES. Aboard these satellites are instruments (or sensors) that take different types of measurements, such as pollutant concentrations. When deciding which satellite to...

Thank you! Using the first link I was able to find this table with annual air quality statistics.

I would like to download PM2.5 station data in Europe on a specific date in 2016 (i.e. a map to compare with satellite estimates). Do you know any sites where I can download historical PM2.5 data over Europe?

I want to find a high-resolution satellite imagery or products that show low-level dust or smoke, especially over the oceans, in real time or with a temporal lag of less than two or three days. I issue air quality forecasts for several days in advance, and I often cannot determine the magnitude...

There is a fire event in Matanzas (CUB). We are trying to identify available earth observation resources to support air quality monitoring. Is there any in particular you recommend we should consider? So far we have this list: AirNow - Fire and Smoke Map and Windy.com

So excited!

If we have ground based monitors already, what is the point of using satellite data?

What are technical challenges inhibiting large-scale use and application of satellite data?

How effective is satellite data in capturing human health-relevant air pollution at the surface?

Is satellite data ever used by itself or is it normally coupled with ground based measurements?
