Calibration Information
Open-path IRGA was calibrated against standard gases, before and after the whole measurement period of the year (=the growing season).
Integrated results of Tura was published as one of series in Ecological Studies Volume 209, titled “Permafrost Ecosystems: Siberian Larch Forests”, eds. by Osawa, Zyryanova, Matsuura, Kajimoto, Wein.
