I am currently working on a project regarding wildfires in the SE United States with focus on the Great Dismal Swamp NWR (GDS) using NASA analysis alongside other organizations analyses. The project will potentially estimate how often fires occurred before European settlement transpired. Then, this project will provide insight on how often a prescribed fire should be conducted to ensure wildfires, when they occur, do not get out of control. I am currently searching for data to apply towards my project that includes parameters such as: Air quality (aerosols), windspeed, precipitation, and biodiversity levels. If possible, I’d like to also obtain imagery showing the swamp before and after the wildfires that devastated the Atlantic White Cedar stand.
The time scale includes the past two decades (2000-2020) but can be limited to particular years such as 2003 and 2008.
For data variables pertaining to air quality, windspeed, and precipitation, I would recommend starting with our Giovanni system, https://giovanni.gsfc.nasa.gov. For the before/after images, you could try Landsat imagery at the Land Processes DAAC for the highest resolution. I do not know the timing of the fires; NASA Worldview (https://worldview.earthdata.nasa.gov/) has MODIS imagery back to 1998, up to 250 meter spatial resolution.
FIRMS or NASA Disasters may be a better resource? https://earthdata.nasa.gov/earth-observation-data/near-real-time/firms
MODIS or VIIRS may be more relevant to your project?
One recent publication produced by the USGS is available publicly here:

Thank you for your reply. However, I am looking for products that are a little more intuitive and products that can be specifically used in ArcGIS. Currently, I am looking for products that display the PM 2.5 analysis in the summers of 2008 and 2011. I have recently come across the MISR Global Aerosol Optical Depth product (https://arcgis.asdc.larc.nasa.gov/portal/home/item.html?id=132c4415455f498592ca77cd220f94b6) and the MOPITT A Priori CO Total Column Day product (https://arcgis.asdc.larc.nasa.gov/portal/home/item.html?id=465d254468764e31b6e38b8e5febb01f) but the data is missing for the period I need. Is there any other product you can suggest that would supply the information requested? If so, could you please supply me with a summary of the product you are suggesting and recommendations and or comments that could enhance how to use them?

AirNow is your one-stop source for air quality data. Our recently redesigned site highlights air quality in your local area first, while still providing air quality information at state, national, and world views. A new interactive map even lets you zoom out to get the big picture or drill down to see data for a single air quality monitor.

**Please look around to see if you can find more information for your research.
Also, We would like to suggest the MYNASADATA website:
The My NASA Data website offers a variety of opportunities to explore Earth Science phenomena of the Atmosphere, Biosphere, Cryosphere, Geosphere, and Hydrosphere using uniquely NASA related content.
Data Visualization: Earth System Data Explorer
Earth System Data Explorer is a visualization tool that allows users to interact with NASA Earth Science satellite data. This tool allows users to explore the data, create custom charts, graphs, and plots to help students visualize the data.

SEDAAC has some great global maps of PM2.5, however because it's global, it will not have good resolution for a small region like the Great Dismal Swap. They don't have all years, but only a few like 2005, 2010, 2015, etc.
