FILE OVERVIEW 
-------------
Directory of Files: CloudRoots_Aircraft_flight1_profile.txt, CloudRoots_Aircraft_flight2_profile.txt, Cloudroots_flaskProfiles2022.csv
File Formats: .txt and .csv
File Naming Convention: 
CloudRoots_Aircraft_flight1_profile.txt and CloudRoots_Aircraft_flight2_profile.txt contain the vertical profiles of CO2 mole fractions measured with an aircraft 10:00 LT (flight 1) and 14:00 LT (flight 2).
Cloudroots_flaskProfiles2022.csv contains the flask measurements of CO2, O2 and 13CO2 during the day at several heights at the ATTO tower.
