Fumes from our new Zero air source in Trailer # 1

We installed a new platinum catalyst zero air generator and had to bake it out which produced some fumes/smoke from 11:25 am - 12:25 pm (local time) in Trailer # 1. We had the trailer door open during this period.

19 august -- cherry picker signal?

The TDCIMS has just moved into the horse trailer next to the PAM experiment. TOday I noticed my particle counts increasing by x10 (see attached fig), and then abruptly return to normal ambient levels (see attached fig). Julie mentioned that the cherry picker might have been on during that time. Do we have a log of cherry picker operation?
