Subject:	ASI/AOS/M1 - Manifold blower not working
Affected Datastreams:	asiaossmpstrhM1.a1
Description	Manifold blower not working, instrument sample flows either zero or different than specified. Sampling through the stack not isokinetic.

Subject:	ASI/ACSM/M1 - Noisy data from low inlet pressure
Affected Datastreams:	asiaosacsmM1.a1
Description	The inlet pressure is low as the result of a clogged critical orifice. Data are corrected for inlet pressure but the signal is low because of very light aerosol loading and are noisy.
Measurements	chloride (Mass concentration of chloride, ambient aerosol in air) org_mx_err (Organic mass spectral error matrix) org_mx (Organic mass spectral matrix) amus (Mass number to charge number ratio of ion fragments (m/z)) ammonium (Mass concentration of ammonium, ambient aerosol in air) nitrate (Mass concentration of nitrate, ambient aerosol in air) total_organics (Mass concentration of total organics, ambient aerosol in air) sulfate (Mass concentration of sulfate, ambient aerosol in air)
