DATA_INFO: Units are pptv for OH interference. UNCERTAINTY: OHI absolute accuracy ~+/- 35% (actually a multiplicative factor of 1/1.35 to 1.35), 2 sigma confidence.

Brune, Penn State, whb2@psu.edu; 814-865-3286 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 can yield large (~1*10^6 cm^-3) variations in individual 20 or 30 second measurements.
