Interannual Variations of Water and Carbon Dioxide Fluxes over a Semiarid Alpine Steppe on the Tibetan Plateau

Figure 1

Seasonal variations of daytime average downward solar radiation (Rs), air temperature (Ta), wind speed (WS), vapor pressure deficit (VPD), precipitation, and soil water content at 5 cm depth below ground (SWC) during the growing season from 2014 to 2017. The daytime average of the variable was calculated with half-hourly data at conditions of Rs > 100 wm⁻².
