PI_CONTACT_INFO: Address: 503 Walker Building, University Park, PA 16802; email: whb2@psu.edu 814-865-3286
PLATFORM: NASA - DC-8 Aircraft - sampling underneath aircraft forward cargo bay
LOCATION: ATom IV: Science Flight #12 -- ANC - PMD
ASSOCIATED_DATA: N/A
INSTRUMENT_INFO: Total OH is from Laser Induced Fluorescence; OH interference is the residual from chemical removal of ambient OH.
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.

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.
