Overview

Field observations reveal soil moisture reduction increases CO2 emissions in permafrost and peatlands, indicating need for improved model simulations.

Key Points

To quantify the impact of soil moisture dynamics on CO2 emissions and SOC decomposition in cold wet ecosystems.
Integrated field observations with global data sets and process-based models.
Analyzed 107 field sites focusing on soil moisture and CO2 emissions relationships.
Utilized model simulations to evaluate hydraulic parameters and SOC decomposition dynamics.
High soil moisture levels protect against SOC decomposition and CO2 release during the growing season.
Soil moisture reduction in near-saturated conditions significantly increases CO2 emissions.
Current models inadequately predict soil water level impacts on SOC decomposition and CO2 emissions.
