NIM/AOS/M1 - Impactor switch stuck in 10 micron mode
DataStreams:nimaosM1.a1
Description:
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.
Suggestions: 
Assume all data from the psap and nephelometers is from the sub 10 micron size cut.
