LI-840 Infrared Gas Analyzer Downtime Resulting in Data Flags and Gaps

July 6, 2020

The LI-840 Infrared Gas Analyzer requires more maintenance and has an observed failure rate higher than other NEON sensors measuring atmospheric carbon dioxide and water vapor. This has led to multiple data gaps and periods of flagged data. We are investigating the issue further.
