Trends in spectrally resolved outgoing longwave radiation from 10 years of satellite measurements

S. Whitburn, L. Clarisse, et al.

This groundbreaking research by Simon Whitburn and colleagues reveals how a decade of data from the infrared atmospheric sounding interferometer has exposed significant shifts in clear-sky spectrally resolved outgoing longwave radiation due to increased greenhouse gases. Discover the impacts of El Niño/Southern Oscillation on natural variability in this enlightening study!

Abstract
This paper uses 10 years (2008–2017) of reprocessed radiances from the infrared atmospheric sounding interferometer (IASI) to evaluate linear trends in clear-sky spectrally resolved OLR (SOLR). Spatial inhomogeneities are observed, reflecting natural variability and long-term changes in greenhouse gases. Increased CO₂ and CH₄ led to significant negative SOLR trends. El Niño/Southern Oscillation activity influenced trends related to natural OLR variability.
