Ozone and Meteorological Monitoring on Walnut Grove Tower

During a period of over 20 years through 2015, T&B Systems operated ozone and meteorological measurement systems installed on an 1800‑foot TV transmission tower in Walnut Grove, CA.   At five levels, wind and temperature instrumentation and five-level long-line sampling systems for multiplexing ozone samples are part of routine measurements used by the California Air Resources Board in pollution forecasting.  Routine maintenance is performed on all equipment, including calibrations and emergency repair of sensors.  In 2005, the systems were upgraded to allow real-time data uploading of the multi-level data to the Internet with the displays and current data available on the web page.
