Mesocosm: Figs1 Exp

10:09 Before final flush Bkgd: 0.14ug/m3 and ~200p/cc

As soon as we start filling via the plant chamber, spikes in particle number and NOx (~5ppb) were observed!

11:29 Nearly finished filling the RC

11:33 Filling complete

11:35 Lights and O3 on! Nucleation started within 5min

44min ALO: We now have two nucleation events similar to Friday’s Exp!

73min ALO: Two modes and 0.13ug/m3

1h40min ALO

14:04 SMPS arched! Changed scanning range down to 237nm

5h45min: 2ppb Limonene were injected.. Nucleation started within a couple of min

5.5h ALO and 40min after Limonene injection

6 HALO, 1h20min after Limonene injection

6h40min ALO, ~2h after limonene injection
