| Description |
This standard operating procedure describes the requirements and guidance for operating Vaisala CL51 Ceilometers (Figure 1) for Measuring Mixing Height within the Washington State Ambient Air Monitoring Network (Washington network). The Mixing Height Layer (MHL) is the height of the layer adjacent to the ground over which pollutants or any constituents emitted within this layer or entrained into it become vertically dispersed by convection or mechanical turbulence. One hour Mixing Height Layer is a required parameter for the U.S. Environmental Protection Agency (EPA) Photochemical Assessment Monitoring Stations (PAMS) Required Site network. |
