PROJECT_INFO: NSF/NASA ATom Mission. 2016 - 2018; Multiple Locations
STIPULATIONS_ON_USE: No restrictions. Contact PI or DM with any questions.
OTHER_COMMENTS: Final Data. OH interference signals from individual 20 or 30 second periods have been averaged together for 150 seconds.
- This averaging compensates for the noise introduced because OH and OH interference measurements are done sequentially,
- and the OH interference signal is the residual of the chemical removal of ambient OH.
- Small variations in ambient OH measurements yield large (~1*10^6 cm^-3) variations in individual 20 or 30 second measurements.
