CONTRAIL Project's Transition to Next Gen Aircraft

On December 4, 2025, the CONTRAIL (Comprehensive Observation Network for Trace gases by Airliner) project is set to begin utilizing the Boeing 787-9 for atmospheric observations, marking a significant evolution in this collaborative undertaking. Launched by Japan Airlines (JAL), the JAL Foundation, the Meteorological Research Institute, the National Institute for Environmental Studies, and Jamco Corporation, this initiative aims to deepen our understanding of the global carbon cycle and climate change mechanisms by consistently measuring greenhouse gases, primarily carbon dioxide (CO2), from commercial aircraft.

The CONTRAIL project stands out as an unprecedented endeavor in using commercial aviation for high-frequency atmospheric CO2 observations, significantly contributing to research both domestically and globally. Data gathered through this project have received favorable evaluations from researchers worldwide, highlighting the project's vital role in scientific inquiry.

The Boeing 787-9, specifically modified for CONTRAIL measurements, will be equipped with two advanced observational devices: the Continuous CO₂ Measuring Equipment (CME) and the Automatic Air Sampling Equipment (ASE). JAL's previous use of the Boeing 777 models has reached a transition point as they retire, potentially limiting the observatory capabilities. However, with the completion of modifications on the next-generation 787-9, and plans for retrofitting an additional four aircraft within the 2025 fiscal year, the observation strategy is being reinforced. Exciting new opportunities for atmospheric observation will emerge, especially over regions like India, the equatorial zone, and the Middle East.

Participating in the CONTRAIL project is part of JAL's commitment to its
