Disclaimer:

Use of SCAQMD’s monitor air quality data is at the user’s discretion and should be done with caution. The intent of the monitoring data is to provide air quality information that is supplemental to the existing SCAQMD air quality monitoring regional coverage. This monitor is intended to represent PM2.5 concentrations, in which the objective is to determine the potential air quality impact of PM2.5 near communities downwind of the CPV Sentinel Plant. Measurements from this monitor alone cannot determine the relative contributions of regional or source-specific origins to PM2.5. Local conditions for pollutants can vary widely based on meteorological conditions and proximity to sources of PM2.5.

Data provided on this website has been reviewed but not yet finalized, and is therefore subject to change. Continuous PM2.5 monitors such as this may be disrupted for periodic weekly maintenance and quality checks, as well as unforeseen power failures and instrument malfunctions. Data provided is representative only of valid hourly averages, whereby hourly averages with less than 75% valid minute averages are omitted consistent with U.S. EPA Quality Assurance guidelines. Finalized data is cross checked with specifications and Quality Assurance Audit thresholds. 

SCAQMD provides no guarantee, either express or implied, as to the accuracy, reliability or completeness of data furnished via the website, maps, or of the forecasts provided in the SCAQMD website. Further, SCAQMD shall not be liable under any circumstances for any direct, special, incidental or consequential damages with respect to any claim by any user or third party as a result of, or arising from, the use of the data, forecasts or maps.
