Line 259: Standard method
Standard method: None
Standard method: <standard method tag>
The standard method refers to one of the recognised standard operating procedures
(SOPs) for VOC (NMHC, OVOC and terpenes) measurements. Please use one of the keywords for
recognised SOPs listed below only if your observations are in fact
conducted following this SOP. If not, you may and should still report
your observations, and fill in this field with "None".
For VOCs, there currently doesn't exist any recognized SOP. The only option here is therefore currently 'None'.
No standard operating procedures is used. Please use
the comment line 262 to specify the details on e.g nafion dryers, o3 removal and instrument uncertainty / measurement standard deviation.
