Poster session
This section is merged with two topics: near-surface wind speed and optical sensor.
Near-surface wind speed is a key variable in the climate system, linking atmospheric circulation, land–atmosphere interactions, and renewable energy production. Long-term changes in wind speed have been reported from station observations, reanalyses, and climate model simulations, with evidence for both large-scale and regional phenomenon across different temporal and spatial scales. These changes can influence climate extremes, alter sectoral risks, and directly affect wind power production, making their understanding critical in the context of a warming world.
Despite significant progress, key challenges remain. These include: (1) identifying and characterizing phenomena and variability in near-surface wind speed across timescales, including extremes and multi-decadal changes; (2) improving the use of station data, reanalyses, and climate model ensembles to quantify historical and projected wind speed changes; (3) attributing observed changes to internal variability, external forcings, and their interactions; (4) assessing uncertainties in model representation of wind speed climatology, variability, and extremes; (5) understanding implications of wind speed changes for wind energy assessments, risks of wind energy droughts, and future renewable energy planning; and (6) advancing methodological approaches, including emergent constraints, detection–attribution frameworks, and statistical or machine learning methods, to improve robustness of results.
Another focus of this session is the global environmental observations using optical imagers, with an emphasis on satellite - based monitoring. Optical imagers play a crucial role in detecting and analyzing large-scale environmental changes across various domains, including the atmosphere, land, ocean, and cryosphere. We aim to bring together contributions directed towards the usage of optical imagers in monitoring environmental variability, evaluating the impacts of climate change, and developing methodological approaches for integrated analysis. The session highlights the potential of new satellite missions including hyperspectral/ polarimetric/ multi-angle spaceborne observations and the importance of international collaboration in advancing global observation capabilities. The list of satellite instruments and their capabilities to be discussed is very broad. It includes EUMETSAT METOP-SG1 mission, JAXA GCOM-C and NASA PACE missions, to name a few.
