The codes are: P - Sample collected using a portable, battery powered pumping unit. Two flasks are connected in series, flushed with air, and then pressurized to 1.2 - 1.5 times ambient pressure. D - Similar to P but the air passes through a condenser cooled to about 5 deg C to partially dry the sample. G - Similar to D but with a gold-plated condenser. T - Evacuated flask filled by opening an O-ring sealed stopcock. S - Flasks filled at NOAA GML observatories by sampling air from the in situ CO2 measurement air intake system. N - Before 1981, flasks filled using a hand-held aspirator bulb. After 1981, flasks filled using a pump different from those used in method P, D, or G. F - Five liter evacuated flasks filled by opening a ground glass, greased stopcock # 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.

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. # # VARIABLE ORDER # site_code year month day hour minute second datetime time_decimal air_sample_container_id value value_unc latitude longitude altitude elevation intake_height method event_number instrument analysis_datetime qcflag MCM 1985 12 4 4 30 0 1985-12-04T04:30:00Z 1985.923801369863 424-85 1620.63 4.59 -77.83 166.6 14.0 11.0 3.0 P 75288 C4 1986-02-27T13:32:00 ...
