Subject: | MAO/TRACEGAS/S1 - Instrument problem |
DataStreams: | maoaosnoxS1.a1 |
Description: | Photolysis cell efficiency decreased from the beginning of the deployment due to some of the LEDs on the converter lamp failing. During February and March, the photolysis cell efficiency decreased to approximately 0.2. NO2 Data is provided during this period using the compromised lamp and adjusted for lower efficiency. |
Suggestions: | NO2 reported data in the newly recovered period is considerably less accurate than expected, (+/-20% is an estimate), but the potential error appears relatively consistent over the period. Because the conversion efficiency is low, the precision is also compromised. |
