Following NOAA guidelines for flagging samples, using three characters to indicate data quality, and "." in each location to indicate data is fine to use. The first character indicates a hard flag (serious issue with datapoint), second character is a soft flag (datapoint has issue, may be okay to use in certain situations), and third character indicates uncertainty with result (datapoint may or may not be included in dataset). ... = Datapoint may be used in almost all cases. X.. = Do not use datapoint. .X. = Use datapoint if conditions are correct. ..X = Use datapoint but check prior to including in dataset. |

| Air samples were collected into evacuated 2.3L glass flasks by air compression pump, using a SHERPA Model 70 sampler. Samples are pressurized to 1.5bar. Value_sd refers to reported errors comprise statistical errors in sample and standard determinations, combined in quadrature with a system error based on the analysis of an ongoing series of measurements of air sample materials (Turnbull et al., 2015). | |||||||||||||||||||||||||||
