A new method for real‐time monitoring of soil CO2 efflux

1. A better understanding of temporal and spatial variability of soil CO2 fluxes is essential to improve model predictions of soil effluxes. To accomplish that goal, high‐frequency and long‐term data sets for model development and validation are needed. However, the cost and high maintenance associated with the current technology make high‐frequency measurements for small or large spatially distributed grids difficult to achieve. Here, we describe a new observational infrastructure for monitoring soil CO2 efflux, which is attractive because of its low cost and low power consumption compared to traditional methods.
