Teriberka station methane measurement
Description:
The reported data are the mean of the CH4 concentrations measured in
two
simultaneously sampled flask, if the difference between them is less or
equal to 6 ppb. Otherwise, the lower of the two measured values is
taken as
a daily value if it does not differ from the smoothed concentration
curve
for more than 2 standard deviations. Technically invalid data are
excluded.
Flag definition:
"+" - concentration difference in two simultaneously sampled flasks less then 6 ppb;
"S" - concentration difference in two simultaneously sampled flasks more then 6 ppb;
"M" - reported value is based on single flask data (one of two flasks is technically invalid).
