Shiv P. Raghuraman, David J. Paynter (Leader, Atmospheric Physics Division, GFDL), V. “Ram” Ramaswamy (Director, GFDL), Raymond Menzel, and Xianglei Huang have been recognized for authoring one of the top viewed articles in Geophysical Research Letters for 2023. Their paper, “Greenhouse Gas Forcing and Climate Feedback Signatures Identified in Hyperspectral Infrared Satellite Observations”, analyzes nearly two decades of data from NASA’s Atmospheric Infrared Sounder to identify spectral signals of greenhouse gas-induced radiative forcing and climate feedbacks. The study connects observed changes in infrared radiation to increases in atmospheric greenhouse gases, providing direct observational evidence consistent with established radiative transfer theory and Earth system response. These findings offer important benchmarks for evaluating weather and climate models and contribute to efforts aimed at improving the observational foundations for long-term environmental prediction.
