Emerging approaches for greenhouse gas flux measurements
Submission #10, submitted by Claire Treat, Aarhus University, claire.treat@agro.au.dk
Quantifying greenhouse gas emissions can be challenging due to strong spatial and temporal heterogeneity in sources, particularly for methane emissions. Advances in instrumentation and low-cost sensor technologies are allowing new types and approaches for measurements to capture these heterogeneous sources. In this session, we welcome contributions using new techniques, such as mobile or UAV-based GHG measurement platforms. We also welcome contributions related to the use of low-cost sensors, including calibration, verification, and measurement strategies, as well as other emerging GHG flux measurement approaches.
Combining data and models to support emissions estimation and policy at local to regional scales
Submission #9
Atmospheric observations of greenhouse gases, and related tracers, provide a wealth of information on their sources and sinks. This information can be harnessed using models of atmospheric transport to gain insights into the spatial and temporal distribution of greenhouse gas emissions and removals. This session focuses on employing models, and especially atmospheric inversions, to improve estimation of greenhouse gas emissions and removals, at national and regional scales. Particular attention will be paid to studies using atmospheric observations to verify and improve national greenhouse gas inventories or to support the monitoring of emission mitigation policies.
Designing the ideal global greenhouse gas monitoring network
Submission #8, submitted by Alex Vermeulen, ICOS ERIC and Lund University, alex.vermeulen@icos-ri.eu
A global effort is needed to transfer from the current Greenhouse Gas observation network on a voluntary basis in scientific mode to an operational network based on a secure governance model. The Global Greenhouse Gas Watch (G3W) initiative aims at setting up such a network. This requires a common set of monitoring approaches and principles applied across observing networks aiming at integration in WMO. The GHG community should define whether and how a tiered network structure can be adopted. The cost-efficient design of the observing network is needed for the implementation at WMO member countries and international community, utilizing common monitoring principles across domains. Strategies for the development of the satellite segment of the GHG observing system are well established but the surface (including over the ocean) network design needs further optimization. In this session we invite contributions from for example the modelling (e.g. TRANSCOM) and observation community for all domains on the following topics:
• Network optimization based on the results of model intercomparisons
• Network optimization based on footprint analysis
• Results of the Observing System Simulation Experiments, including benefits and impact of the optimized networks
Flux Measurements for Immediate Societal Benefits
Submission #7, submitted by George Burba, University of Nebraska, CarbonDew Community of Practice, LI-COR, gburba@unl.edu
Direct flux measurements of heat, water, greenhouse gases (GHGs), and pollutants between the earth’s surface and its atmosphere unlock fair and equitable climate solutions across natural and built environments. Innovations and markets, as well as environmental policies based on such an approach, help resolve global climate and air quality challenges and fairly reward small and big stakeholders.
This session, organized collaboratively by academic research, non-profit organisations, and industry, welcomes ideas and examples of how to utilize direct flux measurements for tangible societal benefits, such as carbon removal, agriculture and forestry, reduction of anthropogenic emissions, various nature-based climate solutions, environmental impact management, and more.
For instance, these measurements can be applied to irrigation scheduling, soil and plant treatments, GHG reduction and sequestration, global warming potential, urban heat management, satellite and model products, industrial and urban emissions, severe weather impacts, air quality management, and can be used as a diagnostic tool for meeting net-zero targets by different organizations, regulatory, policy, and government agencies.
Join us to discuss developing a global paradigm for maximum-integrity, low-latency, and economically sound earth stewardship, anchored in direct flux measurements.
Cross-Scale Responses of Greenhouse Gas Variability to Climate Extremes
Submission #6, submitted by Wenxin Zhang, School of Geographical and Earth Sciences, University of Glasgow, UK; Department of Physical Geography and Ecosystem Science, Lund University, Sweden, wenxin.zhang@glasgow.ac.uk
Climate extremes, such as temperature extremes, heavy precipitation, floods, storms, and compound events, are becoming more frequent and intense under ongoing climate change. These events impose strong and often nonlinear impacts on greenhouse gas (GHG) fluxes (CO₂, CH₄, and N₂O), altering carbon and nitrogen cycling from daily pulses to decadal shifts. Despite increasing evidence, our mechanistic understanding of how ecosystems respond to extremes remains limited, creating substantial uncertainties in predicting biosphere–atmosphere feedbacks.
This session invites contributions that explore GHG variability during and after extreme events across a wide range of ecosystems, including tundra, forests, wetlands, grasslands, croplands, and aquatic environments. We particularly welcome studies employing diverse approaches such as in situ measurements (eddy covariance, chambers, isotopes), experimental manipulations, process-based and Earth system models, and satellite or airborne remote sensing datasets. Integrative research that combines observations and models to disentangle drivers, quantify legacy effects, and upscale local processes to regional or global scales is especially encouraged.
By bringing together observational, experimental, and modelling perspectives, this session aims to identify emerging patterns in GHG responses to extremes, highlight methodological advances across scales, and define critical knowledge gaps. Our goal is to foster cross-disciplinary collaborations and improve future predictions of GHG exchange.
Remote sensing of atmospheric greenhouse gases for climate action
Submission #5, submitted by Mahesh Kumar Sha, Royal Belgian Institute for Space Aeronomy (BIRA-IASB), mahesh.sha@aeronomie.be
Greenhouse gas (GHG) monitoring is carried out using in-situ and remote sensing techniques. While in-situ monitoring is performed by sampling the air either at the Earth’s surface or using airborne platforms to obtain profile information, remote sensing techniques provide complementary information on the total and/or partial columns of the atmosphere. Ground- and satellite-based instruments can retrieve column concentrations of GHGs from the Earth’s surface to the top of the atmosphere. The ground-based remote sensing networks TCCON, NDACC-IRWG and COCCON provide Fiducial Reference Measurements of GHGs used for satellite and model validation studies. Satellites are also continuously improving, both in terms of their observational capabilities and in reducing the uncertainties of the derived products: starting from global GHG Mappers like SCIAMACHY (2002), .. Sentinel-5 Precursor (2017), .. MicroCarb, Sentinel-5 (2025) and upcoming missions such as CO2M, MERLIN. Since 2016, there are also small satellites called Facility Scale Plume Monitors contributing to the quantification of GHG emissions from space.
We invite submissions on new atmospheric remote sensing techniques or sensors, innovative measurement methods, innovative scientific applications; and validation techniques for the evaluation of satellite and model data that are critical for building up monitoring and verification support (MVS) capacity and climate action.
