Filename: Data_Set_for_Kaur_AMT_2022.xlsx Short description: Contains sheet labelled as the site name (HW, RS, EQ). Each sheet contains the OPC-N3, PMS5003 sensors, and FEM data. The sheet “PM-ratio based correlation” provided the data used to get the PM-ratio based correlation. The sheets “RS correction using GRIMM ratio”, “RS correction using opc ratio” and “EQ corrected using EQ ratio” contains corrected PMS data, corrected using the PM-ratio method. The sheets also demonstrated the calculation of RMSE (root mean square error) and NRMSE (normalized RMSE) B. Filename: NA Short description: C. Filename: NA Short description: 2.
