Port of Los Angeles Air Monitoring System Upgrades (as of September 20, 2022)

The Port of Los Angeles is in the process of upgrading its four air monitoring stations with new instrumentation and equipment. The procurement process is expected to be completed by the end of September 2022. The instrumentation and equipment will be installed as they are delivered, with all installation completed by the end of March 2023. At this time, all four air monitoring stations have been upgraded with black carbon aethalometers, PM10 and PM2.5 continuous analyzers, and meteorological instruments. The expected timeline for the installation of the remaining equipment is as follows (See table view below). All four monitoring stations will have upgraded ultrafine particle counters by the end of November 2022; CO, O3, and SO­2 analyzers and calibrations systems by the end of January 2023; and NO­2 analyzers by the end of March 2023. All hardware required to upgrade the data collection, logging, and communication systems have been installed at all four stations. Any changes to the expected timeline will be reflected on this website.

In the meantime, the San Pedro and Wilmington Community stations continue to be operational with existing equipment, with nearly all parameters being measured. The CO and UFP analyzers at the San Pedro Community station and the Black Carbon and SOanalyzers at the Wilmington Community station are offline for repairs. The CO and SOanalyzers will be replaced and are expected back in service by the end of September 2022. The Black Carbon and UFP analyzers will be repaired and these instruments are expected back into service by the end of October 2022 and November 2022, respectively. The Coastal Boundary and Source-Dominated stations are partially operational, with real-time particulate matter and black carbon measured at these stations. Measurement of meteorological parameters are being collected at all four stations with the installation of the new PM continuous analyzers and meteorological instruments. Data for the parameters currently measured at the four stations continue to be uploaded to this monitoring website.
