Slide 6 of 13
- Synthesis of measurements from baseline stations, regional sites, and aircraft campaigns. 2-hr averages for the ground stations. Aircraft measurements were level runs of at least 5-min duration in the PBL and 10-min duration in the FT.
- Submicrometer particles, low RH. Values for total, ambient aerosol would be closer to 1.0
- Boxes show upper/lower quartiles, bars show medians, lines extend to 5&95th percentiles
- This variability induces large variability in forcing
- Note similarity between BND and polluted continental at WSA
- P3 measurements, especially above PBL, are very noisy due to limited sampling duration.
