DATA & FILE OVERVIEW
---------------------


1. File List: CSV files for all the participants are enclosed in the Cohort and Colocation folders.


   A. Filename: ATM_Cohort1_Rawdata

        
   B. Filename: ATM_Cohort2_Rawdata


   C. Filename: ATM_Colocation1_Rawdata


   D. Filename: ATM_Colocation2_Rawdata


2. Relationship between files: Cohort 1 and Cohort 2 dataset was used to report the real-life exposure concentration for the participants. Colocation 1 and Colocation 2 dataset was used for performing correlation analysis with CDPHE sensor dataset. One or two monitors used by the participants had issues with data upload so the corresponding dataset for these monitors could contain blank values.   


3. Software-specific information: The file size could be too large to open these files via Excel so the use of data processing software such as Python, R, or Matlab is recommended.
