Homogeneous Boundary Layer and Good AQI Levels

Mostly clear skies prevailed throughout most of our operation, with clouds (red counts) advecting at altitudes between 5-6 km. A homogeneous boundary layer was observed, at a height of 1.5 km, during today's observations. Good PM2.5 AQI levels were recorded at Maryland Department of the Environment Oldtown site.
