This is a (primarily MATLAB-based) working folder for interaction with the IMPROVE Aerosol Dataset, available from http://vista.cira.colostate.edu/Improve/improve-data/
Figures are output in the '/Figures' subfolder.
A list of variables, their units, descriptions, etc. is provided in the Excel file 'IMPROVE Aerosol Variables.xlsx' (or from the source data repository itself).
A quick list of the chemical compositional variables included in the .mat import ('2021-07-30_IMPROVE.mat') is provided here:
