# method:long_name : air_sample_collection_method
# method:comment : Air sample collection method. See provider_comment if available.
# method:provider_comment : A single-character code is used to identify the sample collection method. The codes are: A - The automated or manual filling of a whole air sample using the Programmable Flask Package (PFP) and Programmable Compressor Package (PCP)air sampling devices. The air sample is contained in a 0.7 liter borosilicate glass container (flask) fitted with two Glass Expansion high vacuum glass piston valves sealed with PTFE O-rings. The flasks are typically flushed with 10 liters (aircraft samples) or 75 liters (tower samples) of ambient air and then pressurized to 40 psia. Air is delivered through an intake tube using two diaphragm pumps connected in series and controlled with a microprocessor. The flow rate is approximately 15 L/min at sea level. See Sweeney et al. 2015 and Andrews et al. 2014 for more details. B - Air samples are collected as with method ‘R’, but with an additional drying step using one of several techniques. In one method, e.g. site=ACT, air samples were dried with a two-stage chiller cooled to 5 degrees C; those taken below 3000 m MSL were also pressurized to 40 psia to further facilitate air sample drying (Baier et al. 2019). At tower sampling sites, M&C chillers with temperatures set to approximately 3 degrees C and sub-ambient pressure due to high flow are used (Andrew et al. 2014). At CRV tower, a two-stage chiller set to -26 degrees C is used. C - Air samples are collected as with method ‘A’, but the sample air is dried before sample collection. Flasks are not pre-filled with ambient air before flushing and collecting the air sample. I - Air is sampled from a 15L spherical stainless steel mixing volume after being filled with ambient air that was pulled through an M&C Techgroup Model ECP 20-2 gas chiller using an integrating compressor and mass flow controller. The two stainless steel dryer traps are plumbed in series, held at approximately 5 degrees C and the condensed water is removed with a peristaltic pump. The integration starts with a high flow rate of 3.8 SLM and decreases over time to 0.29 SLM over 1 hour. The resulting one hour time averaged ambient air sample is compressed into a 0.75 liter borosilicate glass container (flask) fitted with 2 Glass Expansion high vacuum glass valves and PTFE O-rings. The flask is typically filled to 40 psia. (See Turnbull, J.C., Guenther, D., Karion, A., Sweeney, C., Anderson, E., Andrews, A.E., Kofler, J., Miles, N.L., Newberger, T., Richardson, S.J., Tans, P.P., 2012. An integrated flask sample collection system for greenhouse gas measurements. Atmos. Meas. Tech. 5, 2321-2327.) R - Air samples are collected as with method 'A', but with an additional glass conditioning step known as “prefilling”. During prefilling, the glass containers are flushed and filled with ambient air and then vented and flushed immediately before air sample collection. This is a glass conditioning step that addresses glass wall effects of the gasses of interest (Andrews et al. 2014).
# event_number:long_name : Unique_Air_Sample_Event_Number
# event_number:comment : Identifies each discrete air sample collected at some time and location with a unique sample event number.  The event number (reported as a string) can be used to relate measurements of different trace gases and isotopes from the same sample.

# qcflag:long_name : quality_control_flag
# qcflag:comment : This quality control flag is provided by the contributing PIs. See provider_comment if available.
# qcflag:provider_comment : This is the NOAA 3-character quality control flag.  Column 1 is the REJECTION flag. An alphanumeric other than a period (.) in the FIRST column indicates a sample with obvious problems during collection or analysis. This measurement should not be interpreted. Column 2 is the SELECTION flag. An alphanumeric other than a period (.) in the SECOND column indicates a sample that is likely valid but does not meet selection criteria determined by the goals of a particular investigation. For example, it might not have been obtained during 'background' conditions.  Column 3 is the INFORMATION flag. An alphanumeric other than a period (.) in the THIRD column provides additional information about the collection or analysis of the sample. A P in the 3rd column of the QC flag indicates the measurement result is preliminary and has not yet been carefully examined by the PI.  The P flag is removed once the quality of the measurement has been determined.
