  1. Optionally, for other instruments currently deployed at your site:
    • Enter the instrument model in the INST_MODEL row. Select from the list of controlled vocabulary (CV) for INST_MODEL on the LIST(xxx) sheet.
    • Enter the instrument serial number in the INST_SN row.

    • Enter the date that this configuration first applies in the INST_DATE row.

 

  1. Report previous configurations of the instruments currently at your site. Repeat step 2 for each previously used configuration of the sonic anemometer and step 3 or 4 for each previously used configuration of a gas analyzer. Repeat step 5 for previously used configurations of other instruments currently at your site.

 

  1. Report the configuration of instruments previously deployed at your site but since removed, going back to the start of data collection at the site if possible. Repeat step 2 for each new installation of a sonic anemometer and step 3 or 4 for each new installation of a gas analyzer. Repeat step 5 for new installations of other instruments that have since been removed.

 

  1. For each sonic anemometer – gas analyzer pair at your site used to measure gas flux via eddy covariance:
    • Enter the sonic anemometer model in the INSTPAIR_MODEL_1 Select from the list of controlled vocabulary (CV) for INST_MODEL on the LIST(xxx) sheet.
    • Enter the sonic anemometer serial number in the INSTPAIR_SN_1 row.
    • Enter the gas analyzer model in the INSTPAIR_MODEL_2 Select from the list of CV for INST_MODEL on the LIST(xxx) sheet.
    • Enter the gas analyzer serial number in the INSTPAIR_SN_2 row.
    • Enter the vertical separation in meters between the two instruments, using negative values if the gas analyzer is below the sonic anemometer.
    • Enter the east-west separation between the two instruments, using negative values if the gas analyzer is west of the sonic anemometer.
    • Enter the north-south separation between the two instruments, using negative values if the gas analyzer is south of the sonic anemometer.
    • Enter the date that these vertical, east-west and north-south separation values first apply in the INSTPAIR_DATE row. Use YYYYMMDD format.

 

  1. Optionally, for other pairs of instrument used at your site to measure one variable:
    • Enter the model of the first instrument in the INSTPAIR_MODEL_1 Select from the list of CV for INST_MODEL on the LIST(xxx) sheet.
    • Enter the serial number of the first instrument in the INSTPAIR_SN_1 row.
    • Enter the model of the second instrument in the INSTPAIR_MODEL_1 Select from the list of CV for INST_MODEL on the LIST(xxx) sheet.
    • Enter the serial number of the second instrument in the INSTPAIR_SN_1 row.
    • Enter the vertical separation in meters between the two instruments, using negative values if instrument 2 is below instrument 1.
    • Enter the east-west separation in meters between the two instruments, using negative values if instrument 2 is west of instrument 1.
    • Enter the north-south separation in meters between the two instruments, using negative values if instrument 2 is south of instrument 1.
    • Enter the date that these vertical, east-west and north-south separation values first apply in the INSTPAIR_DATE row.

 

  1. If the vertical, east-west and north-south separation has changed since a pair of instruments was installed, repeat step 8 or 9 to report these earlier separation distances.

 

  1. Report the vertical, east-west and north-south separation of instruments pairs previously deployed at your site but since removed, going back to the start of data collection at the site if possible. Repeat step 8 for each sonic anemometer – gas analyzer pair that has since been removed and step 9 for other instrument pairs that have since been removed.
