monitoring location are presented in Table 1.
Different degrees of measurement error for different air pollution components related to characterizing exposure at a central monitoring location is another problem because more consistent associations tend to be found with air pollution components with less measurement error (Zeger et al. 2000).
The average PM2.5 in the previous 12 months from the spatial temporal model was 12.0 μg/m (SD 2.8 μg/m) and from the nearest monitoring location was 12.7 μg/m (SD 3.1 μg/m).> -wrap-foot> aValue not age adjusted.
Temporally stable monitoring locations were identified.
For this field site, approximately three neutron probe monitoring locations were required to determine mean soil water depletion (±2 cm) for the field or for a management zone.
Briefly, the annual averages at the 150 NYCCAS monitoring locations were used as the response in multiple regression models developed to assign exposure to maternal residences.
All monitoring locations were geocoded using a national geographic information system (GIS) database (Kadaster, Apeldoorn, the Netherlands) that contained coordinates for all home addresses in the Netherlands.
To avoid extrapolation, covariates at prediction locations beyond their range among the monitoring locations were set to the appropriate minimum or maximum among the monitoring locations (doing so within each region for time-varying covariates).
Indoor measurements were conducted in a room where the children were likely to spend time and that was considered to be broadly representative of the specific in-school microenvironment; across the four schools, indoor monitoring locations were a computer room, a library reference room, a classroom, and a library.
Eight years of day-level data from Atlanta, GA, for ten ambient air pollutants collected at a central monitor location were classified using SOM into a set of day types based on their day-level multipollutant profiles.
