Sentence examples for apportionment models from inspiring English sources
One approach is to use receptor-based source apportionment models to distinguish sources.
These data will improve the accuracy of emission inventories, dust dispersion, transport, and source apportionment models, and help design and evaluate dust control strategies.
In the fields of pollution sciences (air or water), source apportionment models aim to re-construct the emissions from different sources of pollutants based on ambient data registered at monitoring sites [32].
To investigate the impact of the number of observations on molecular marker-based positive matrix factorization (MM-PMF) source apportionment models, daily PM2.5 samples were collected in East St . Louis IL, from April 2002 through May 2003.
Only few studies used source apportionment modelling to identify common sources of both VOCs and PM2.5.

Canada recently developed such a method that offers credible emission characteristic data from stationary combustion systems that can be used in source apportionment modeling.
Monthly and annual average concentrations of molecular markers in the source apportionment model showed lower sensitivity to source profiles than daily measurements, which has implications to the design of source apportionment studies.
A load apportionment model (LAM) is used to show how point sources contribution may have been overestimated in previous studies, because of a biogeochemical process mimicking a point source signal.
The sensitivity of a source apportionment model to mobile source profiles was examined to determine the impact of using non-local mobile source profiles in chemical mass balance (CMB) models.
The second approach is based on an instrumented air quality model which tracks the formation of ozone within the simulation and assigns the source of that ozone to pre-identified categories (i.e., source apportionment modeling).
