Subject:	MAO/ACSM/S1 - Noise in data
DataStreams:	maoaosacsmS1.b1
Description:	There continue to be issues with noise in the ACSM in the MAOS A container located at the site near Manacapuru in Amazonas, Brazil. The noise is intermittent, ongoing, and persistent.

Subject:	MAO/ACSM/S1 - critical orifice clog and resulting noise issues
DataStreams:	maoaosacsmS1.b1
Description:	The critical orifice clogged at the beginning of the specified period and there was a substantial drop in the inlet pressure. the orifice was cleaned and reinstalled, but there was significant instrument noise. A second cleaning and reinstallation solved the problem.
