Concurrent spatiotemporal daily land use regression modeling and missing data imputation of fine particulate matter using distributed space-time... (Publications)
(D-STEM) software was developed. We trained the model using daily mean ambient particulate matter ≤2.5 μm (PM2.5) data measured hourly in 2015 at 30 regulatory monitoring network stations within the megacity [...] Iran. Since a substantial amount of measured data were missing (48% of the total number of daily PM2.5 observations), we used the D-STEM to impute missing data and compared the missing imputation performance [...] in MAPE of 28.3%. The spatiotemporal R-squared was 0.73 and the average...
