Each new gas is flushed through the Licor Analyzer for 2 minutes prior to a stop-flow measurement.; Standardization frequency: Every 5 hours; Standard gas manufacturer: The analyzer is calibrated every 5 hours with field standards that in turn were calibrated with primary standards that are directly traceable to the WMO X2007 scale. The zero gas is ultra-high purity air.; Standard gas concentration: Std 1: EKZTPF4, 0.00 ppm, owned by INIDEP, used every ~4.5 hours. Std 2: LL125773, 206.61 ppm, owned by INIDEP, used every ~4.5 hours. Std 3: LL125769, 409.49 ppm, owned by INIDEP, used every ~4.5 hours.

(2009).; Temperature correction method: Details of the data reduction are described in Pierrot, et.al.
