Processing Record for this file: (Make notes here unique for this file) Loading 3/1 - 4/1/2014 Data loaded directly from DMF Processed SO2 data normally. These data are taken with a ~10-s time constant on the instrument. During the beginning of the month, the instrument flash lamp failed, at first intermittently and then completely. The data grew increasingly noisy. The ambient signal appeared near background when the instrument was functioning. No valid data reported after 2014-03-08 01:49 and several shorter period prior to this.
