Photon Informed Ecology Lab
We combine remote sensing and data science to understand terrestrial ecosystems in a changing climate — linking optical signals to the physical and biological processes that drive them, from leaf to globe.
What we study
Our research is multi-scale in nature and mechanistically links remote sensing observations with biological processes — with a particular emphasis on quantifying carbon and water fluxes.
Remote sensing of photosynthesis
Detecting changes in photosynthesis when changes in structure are decoupled from changes in function.

Building and interpreting ET and WUE products to support conservation, fire risk assessment, and water management.
Learn more →Proximal remote sensing
Bridging the gap between leaf and plant-scale observations, flux towers, and air- and spaceborne remote sensing.

New Paper: Integrating Landsat and ECOSTRESS for Field-Scale Evapotranspiration
A new paper co-authored by Dr. Pierrat in Remote Sensing of Environment tests how much adding ECOSTRESS thermal observations to Landsat improves field-scale evapotranspiration mapping.

New Paper: OCO-3 Meets ECOSTRESS — Diurnal Water-Use Efficiency from Space
A new paper led by Dr. Pierrat in Geophysical Research Letters tests whether co-located OCO-3 fluorescence and ECOSTRESS thermal observations from the International Space Station can track how ecosystems balance carbon uptake and water loss over the course of the day.

New Paper: Mapping Lithology and Mineral Alteration with Thermal Infrared Spectroscopy
A new paper co-authored by Dr. Pierrat in the International Journal of Applied Earth Observation and Geoinformation uses thermal infrared spectroscopy to map rock types and hydrothermal alteration in geothermally active areas.
