The importance of monitoring leaf temperatures

Forests represent a considerable carbon sink and play a vital role in moderating local air temperatures, but data analysing their response to climate change is currently insufficient. Previous studies have shown that the temperature of individual leaves in the forest canopy can sometimes differ greatly from the surrounding air, and this can cause inaccuracies in Earth system data that simulates temperature-sensitive processes like photosynthesis and respiration.
Long-term, ongoing monitoring covering a range of sites and tree species is required to observe and understand forest response to climate change, and how this might affect the accuracy of climate models.

Establishing a global research network

netCTF is a collaborative project, led by Â鶹´«Ã½, that aims to establish an international network of researchers monitoring forest canopy temperatures across five continents. The findings will help develop understanding of how forests are responding to climate change and, hopefully, be an impetus for action.
This vital data will inform climate modelling and forest management policy, and will also be useful for scientists in other research areas. For example, it could be used to test how well vegetation models predict leaf temperature, or it could even help in validating remote sensing and satellite imaging.

Understanding leaf temperature is important because it affects many critical functions and processes... If the leaves in forests are too hot and are unable to cool down, trees could die, further exacerbating the problems of global warming and climate change.

The project in action

  • Initial forest canopy temperature data workshop hosted at Â鶹´«Ã½ to establish agreements on data-sharing and highlight priority methodologies.
  • Collaborative research network created across five continents, with 12 sites featuring thermal imaging cameras for canopy monitoring. Of these sites, two are newly established with TIC equipment: BIFoR FACE (UK); Bobiri Forest (Ghana).
  • International partner meeting on global data synthesis of forest canopy temperatures. A cross-site analysis of contemporary canopy temperature response to climate change to be published, evaluating site differences, as well as implications for forest functioning.
