Welcome to your resource for exploring approved Standard Operating Procedures (SOP) for Meteorological Parameters for monitoring organizations (MO) within CARB’s Primary Quality Assurance Organization (PQAO).
SOPs are organized by meteorological parameter: barometric pressure, relative humidity, temperature, wind direction, and wind speed. SOPs for each parameter outline procedures for operating and maintaining air monitoring instruments and ensure accurate measurement of the parameters.
Approved quality management documents* within CARB's PQAO are shown based on their origin:
- A#: Addendum number assigned to an addendum developed by a monitoring organization and approved by CARB.
- CARB: Developed and approved by CARB.
- MO: Developed by a monitoring organization within CARB's PQAO and approved by CARB.
- --: Not applicable.
