Lend us your thermal images!

Please consider taking part of an open repository initiative of thermal images hosted at the following website: https://trench-ir.azurewebsites.net/. If you are acquiring thermal images of plants, animals, or their environment using FLIR cameras, we would like you to share your images as part of this initiative. We welcome images from research grade cameras or from hand-held mobile phone provided the images are radiometric jpgs.

Infrared imagery offers a unique opportunity to see biophysical properties in real time. We can watch organisms heat up, cool down, and generally transfer heat back and forth throughout their environment. In the TrEnCh-IR Project, we use infrared imagery to help people see the world from a thermal perspective because we believe it’s an intuitive first step to understanding microclimate and the impacts of warming.

The TrEnCh-IR project is part of a larger initiative interested in Translating Environmental Change into organismal responses. Our goal is to build case studies of how animals are impacted by climate change to improve our approach to climate change biology education, policy, and research.

Mission

FLIR cameras are extensively used, increasingly so with the availability of FLIR thermal cameras that attach to phones. However, the cameras produce images in a non-standard format (radiometric jpgs) and analyzing the images requires purchasing expensive FLIR software. Project collaborator Tattersall has produced an open source R package (ThermImage, https://github.com/gtatters/Thermimage) that converts the images into standard formats and extracts additional data to allow analysis in commonly used and open source software such as ImageJ. Our web service makes these tools more accessible. We aim to empower more people to view the world from a thermal perspective.

Our thermal image repository will allow researchers to analyze the surface temperatures of disparate organisms in diverse environments. Education and outreach resources promote understanding how organisms experience their environment. We aim to maintain the repository long term, but can not guarantee longevity at this point. An ongoing aim is to use initial AI algorithms, potentially combined with crowd sourced landmarking, to distinguish organisms, particular body parts, and backgrounds. Our interface will allow users to explore the images to understand how organisms interact with their environments.

Motivation

Currently most analyses of the impacts of climate change on organisms are based on air temperatures, but body temperatures of ectotherms can differ from air temperatures by tens of degrees. Additionally, the characteristics and behaviours of organisms can result in their experiencing different body temperatures even in the same environment with repercussions for species interactions. Moving beyond air temperatures to consider body and surface temperatures may thus be essential to accurately forecasting climate change impacts. Thermal images provide compelling visual examples of why we need to move beyond air temperatures in examining climate change impacts as well as data that can inform approaches for modelling how organisms interact with their environment.
