Outline of Final Research Achievements |
I measured the carbon dioxide flux with automatic closed chamber system through two winters from 2016 to 2018 in a semiarid grassland in Mongolia. During the mid-winter, CO2 efflux rates were almost zero. In spring and autumn, CO2 flux showed diurnal variation with soil temperature changes. In addition, a soil-thaw CO2 pulse was observed in 2018 spring.
