Summary
This summary is machine-generated.A new project uses regular passenger flights to monitor greenhouse gas emissions. The GOBLEU instrument, developed by JAXA and ANAHD, provides valuable data for climate mitigation efforts.
Area Of Science
- Earth and Environmental Sciences
- Atmospheric Science
- Climate Change Research
Background
- The Greenhouse gas Observations of Biospheric and Local Emissions from the Upper sky (GOBLEU) project is a collaboration between JAXA and ANAHD.
- It aims to support subnational climate mitigation by collecting greenhouse gas (GHG), nitrous dioxide (NO2), and Solar-Induced Fluorescence (SIF) data.
- A novel, luggage-sized instrument based on space remote-sensing techniques was developed for easy installation on passenger aircraft.
Purpose Of The Study
- To visualize progress in climate mitigation efforts through enhanced GHG data collection.
- To support subnational climate mitigation strategies with real-time emissions and removals data.
- To demonstrate the feasibility of using regular passenger flights for atmospheric monitoring.
Main Methods
- Development of a compact, luggage-sized instrument utilizing JAXA's space remote-sensing technology.
- Installation of the GOBLEU instrument on a coach-class passenger seat without aircraft modification.
- Initial observation campaign on a flight from Tokyo to Fukuoka, activating the NO2 module.
Main Results
- Collected high-spatial-resolution NO2 data were compared with TROPOMI satellite data and ground-based monitoring stations.
- GOBLEU and TROPOMI data showed similar major concentration patterns, but GOBLEU revealed fine-scale differences potentially indicating new emission information.
- Analysis of NO2 spatial correlation highlighted the impact of time differences between emission markers and the significance of co-located observations.
Conclusions
- The GOBLEU project enables cost-effective, frequent aircraft-based monitoring of greenhouse gas emissions.
- The GOBLEU instrument is theoretically compatible with most commercial passenger aircraft without modifications.
- Expansion of observation coverage and international partnerships are planned to enhance global climate mitigation cooperation under the Paris Agreement.

Gas chromatography–mass spectrometry (GC–MS) is the combination of analytical techniques of gas chromatography and mass spectrometry in a single instrument for analyzing a mixture of compounds. The gas chromatograph separates the compounds in the mixture, and the mass spectrometer analyzes each compound separately to determine the molecular masses and molecular structures.
A gas chromatograph consists of a long, narrow capillary column with a polysiloxane coating on the inner wall....
The instrumentation of atomic emission spectrometry (AES) involves various components, including atomization devices that convert samples into gas-phase atoms and ions. There are two main types of atomization devices: continuous and discrete atomizers. Continuous atomizers, like plasmas and flames, introduce samples in a constant stream, while discrete atomizers inject individual samples using syringes or autosamplers. The most common discrete atomizer is the electrothermal atomizer.
In gas chromatography, different detectors are employed to meet specific analytical needs. These detectors are often categorized based on their detection mechanisms and the types of compounds they are best suited to analyze. Thermal Conductivity Detectors (TCD), Flame Ionization Detectors (FID), and Electron Capture Detectors (ECD) represent common categories, each with unique operating principles and applications. However, beyond these, several other detectors are designed for more specialized...
