GRW/AOS/M1 - CCN Detector misalignment
The CCN signal was unusually low about 100 particles/cc. The %SS growth curves were asymmetrical. Upon consultation with the manufacturer, DMT, it was predicted that the OPC detector was clogged or misaligned. I had the tech, Carlos, remove the detector and ship it back to Boulder. The detector was cleaned. An o-ring for a lens wasn't properly seated. The OPC was sent back to GRW and installed. Data looks normal after the reinstallation on July 13th.
Don't use the data during this time.
