More realistic warming by including plant feedbacks: A new field-tested control method for infrared heating

摘要

Infrared heating is a technique that allows warming experiments to be conducted in open-air conditions. Several improvements have been made since the method was introduced two decades ago, but none of these succeeded in reconciling controllability with an adequate consideration of vegetation responses that can counteract or reinforce warming. In an earlier conceptual study, we proposed a new infrared heater control method based on energy balance calculations that offers both custom-adjustable target temperatures and unconstrained vegetation responses. Here, we refine that concept, and test the control method under field conditions.
