Project covering analysis of OCO-2 NASA data for tracking atmospheric Carbon (XCO2), and exploring suitability for policy evaluations.

The data folder contains XCO2 (Atmospheric Carbon Di-Oxide) data retrieved from:

NASA's GES DISC: Goddard Earth Sciences (GES) Data and Information Services Center (DISC) Data Center https://disc.gsfc.nasa.gov/information?page=15

from the OCO-2 satellite, over a period ranging from 2014 and, the time of writing - May 2021. https://disc.gsfc.nasa.gov/datasets/OCO2_L2_Lite_FP_10r/summary?keywords=OCO-2

This was cropped at source for areas surrounding Sammis Plant https://www.gem.wiki/Sammis_Plant

in Ohio, US, and lat-long regions up to 200km away, to observe XCO2 flux correlated with Plant shutdowns or activity. This was then processed in:

with snippets included in the r_code folder.
This code is for references purposes - running this linearly is not advised. Be sure to replace USERNAME/URLs as appropriate, and run package.install() for required libraries. the getDataNC4 method handles filtering logic.

Some of the graphic codes, with other usage patterns can be seen under code.Rhistory. Relevant plots are exported to the plots folder.
