Table 11 List of attributes in the files originating from the off-axis integrated cavity output spectroscopy instrument in the ARM container, and archived on the ARM Data Archive.

time

Date and Time of measurement in Coordinated Universal Time.

base_time

Base time (“2019-10-11 00:00:00” in our case).

time_offset

Time offset from base time.

seconds_after_calibration

Seconds after calibration.

co

Carbon monoxide mixing ratio calculated with nominal sensitivity correction in parts per million.

qc_co

Quality control flag. This field contains bit packed integer values, where each bit represents a QC test on the data. Non-zero bits indicate the QC condition given in the description for those bits (see file mosaoscoM1.b1.20191011.004433.header.txt for a full description); a value of 0 (no bits set) indicates the data has not failed any QC tests.

n2o

Nitrous oxide mixing ratio calculated with nominal sensitivity correction in parts per million.

qc_n2o

Quality control flag. This field contains bit packed integer values, where each bit represents a QC test on the data. Non-zero bits indicate the QC condition given in the description for those bits (see file mosaoscoM1.b1.20191011.004433.header.txt for a full description); a value of 0 (no bits set) indicates the data has not failed any QC tests.

h2o

Water vapor mixing ratio calculated with nominal sensitivity correction in parts per million.

qc_h2o

Quality control flag. This field contains bit packed integer values, where each bit represents a QC test on the data. Non-zero bits indicate the QC condition given in the description for those bits (see file mosaoscoM1.b1.20191011.004433.header.txt for a full description); a value of 0 (no bits set) indicates the data has not failed any QC tests.

co_dry

Carbon monoxide mixing ratio corrected for water vapor concentration and calculated with nominal sensitivity correction in parts per million.

qc_co_dry

Quality control flag. This field contains bit packed integer values, where each bit represents a QC test on the data. Non-zero bits indicate the QC condition given in the description for those bits (see file mosaoscoM1.b1.20191011.004433.header.txt for a full description); a value of 0 (no bits set) indicates the data has not failed any QC tests.

n2o_dry

Nitrous oxide mixing ratio corrected for water vapor concentration and calculated with nominal sensitivity correction in parts per million.

qc_n2o_dry

Quality control flag. This field contains bit packed integer values, where each bit represents a QC test on the data. Non-zero bits indicate the QC condition given in the description for those bits (see file mosaoscoM1.b1.20191011.004433.header.txt for a full description); a value of 0 (no bits set) indicates the data has not failed any QC tests.

gas_pressure

gas_temperature

Cell sample temperature in degrees Celsius.

ambient_temperature

Ambient temperature of instrument in degrees Celsius.

set_point_for_MFC_1

Set point for mass flow controller 1 in cm³/min.

mass_flow_through_MFC_1

Actual mass flow through mass flow controller 1 in cm³/min.

valve_position_MFC_1

Valve position for mass flow controller 1 (0 for open, 1 for closed, −1 for error).

set_point_for_MFC_2

Set point for mass flow controller 2 in cm³/min.

mass_flow_through_MFC_2

Actual mass flow through mass flow controller 2 in cm³/min.

valve_position_MFC_2

Valve position for mass flow controller 2 (0 for open, 1 for closed, −1 for error).
