NIM/AOS/M1 - Impactor switch stuck in 10 micron mode
A wire came loose in the ball valve that switches between the two impactor size cuts. The impactor was stuck on the sub 10 micron size cut during this period of time. There was no data from the sub 1 micron size cut during this time.
Assume all data from the psap and nephelometers is from the sub 10 micron size cut.
