Ecosystem respiration (ER) is the largest source of biogenic CO 2 to the atmosphere, and its temperature sensitivity (Q 10 ) before reaching maximum values is crucial for understanding land–climate feedback. However, despite decades of studies showing that Q 10 varies considerably across space, time, and biomes, the mechanisms underlying this variability remain unresolved. Here we demonstrate that global variation in Q 10 can...
Clockwise or Counterclockwise: Hysteresis in the Response of Ecosystem Respiration to TemperatureNARA Subscribed
Ecosystem respiration (ER) often responds asymmetrically to seasonal warming and cooling, producing thermal hysteresis. Yet, its global patterns and drivers remain unknown. Here, we used daily ER data from 324 eddy‐covariance sites worldwide and revealed two contrasting hysteresis patterns in the temperature response of ER: clockwise hysteresis (ER is higher during the warming than cooling season) at 173 sites and counterclock...
Slower Soil Nitrogen Transformations Under Longer‐Term Warming and the Consequences for Plant GrowthNARA Subscribed
Climate warming is expected to stimulate soil nitrogen (N) transformations, thereby increasing the supply of available N to support plant growth and carbon (C) assimilation. However, it remains uncertain whether this stimulatory effect on soil N transformations can persist over time to sustain plant growth and N uptake. This study combines a global meta‐analysis with a local warming experiment with 7 years to shed light on how...
Methane (CH 4 ) uptake in alpine ecosystems is an important component of the global CH 4 sink. However, large uncertainties remain regarding the magnitude and spatial patterns of CH 4 uptake, owing to its extensive spatial variability, diverse controlling factors, and limited regional‐scale observations. Here, we investigated field ecosystem CH 4 uptake along a 3200‐km transect across various alpine grasslands on the Qinghai–T...
Construction of a meteorological application system based on BDS ground-based augmentation network and water vapor products validationNARA Subscribed
The national Beidou Navigation Satellite System (BDS) ground-based augmentation network (BGAN) of China is constructed with the existing GNSS observation resources of industrial sectors and local governments, based on the concept of joint building and sharing with sustainable development. This study provides a detailed introduction to the design, construction and operation of a meteorological application system based on BGAN,...
