Meteorology and Air Quality Modeling for the 2012 24-Hour PM2.5 Plan for the San Joaquin Valley
This page last reviewed December 05, 2012
This page contains the results for the meteorology and air quality simulations conducted by the staff of Air Resources Board in support of the 2012 24-hour PM2.5 Plan for the San Joaquin Valley nonattainement area. The base year was 2007 and the future year was 2019. Results are presented for the first and fourth quarters. The Draft Modeling Protocol contains detailed information on how the modeling was conducted (This document will open in a new tab or window).
Meteorology Modeling Results (Mesoscale Model 5):
Hourly model results of wind speed, wind direction, temperature, relative humidity, and solar radiation near the surface are compared against hourly surface observations.
