Subject: | ASI/TRACEGAS/M1 - Slow return to ambient measurement after HNO3 calibration |
DataStreams: | asiaosnoxM1.a1 |
Description: | Nitric acid permeation source is used to calibrate at 06:00 on odd days. The response on the NO2 and NOy channels is large and takes excessive time to recover after the calibration. This is apparent as a spike in the data after the calibration. Users should ignore this spike. HNO3 calibration was turned off. |
