Daily Global Methane Super-Emitter Detection and Source Identification With Sub-Daily Tracking

(Geophysical Research Letters)

Mitigating large, concentrated methane emissions such as gas leaks is vital to curb global warming. Satellites can help in finding the largest methane emitters. We use the Visible Infrared Imaging Radiometer Suite (VIIRS) satellite instruments to observe large methane plumes with a high resolution of 750 m. We show that using the three VIIRS instruments improves current abilities to track large methane emissions. Together with the Sentinel-3 satellites we can now image methane plumes multiple times a day. This is especially important for plumes that result from short-duration emission events. Furthermore, we show that because the observations of one of these VIIRS satellites overlap with those of the TROPOMI instrument, we can directly compare the low-resolution, high-precision measurements of TROPOMI with the high-resolution, but high-noise measurements of VIIRS. This means we can use VIIRS to zoom in on plumes detected by TROPOMI to identify the responsible facility and compare the observed methane plumes, which we find agree well within their respective uncertainties.

AI and geospatial technology: Twin engines driving sustainability in real estate

GeoBusiness Blog

Dr Yishuang Xu, Associate Professor of Real Estate at the University of Manchester, explores how artificial intelligence and geospatial technology are transforming sustainability in the built environment. With the UK real estate sector facing growing pressure to reduce carbon emissions, these technologies are emerging as powerful tools to unlock efficiencies, inform smarter planning, and future-proof buildings. From AI-driven energy optimisation to geospatial insights for resilient site selection, discover how these “twin engines” are reshaping real estate’s environmental impact.
