Venkatachalam Ramaswamy (V. "Ram" Ramaswamy) is the Director of the Geophysical Fluid Dynamics Laboratory of the National Oceanic and Atmospheric Administration (NOAA) Office of Oceanic and Atmospheric Research (OAR), studying climate modeling and climate change. "A leading climate scientist", his work is cited as supporting evidence for significant stratospheric climate change. He focuses in particular on radiative transfer models and the hydrologic cycle in the atmosphere. He has actively supported the development of supercomputing approaches that enable researchers to achieve higher resolution and greater complexity in climate models. As a lead author involved in the Intergovernmental Panel on Climate Change (IPCC), Ramaswamy's contributions (along with the contributions of many scientists) was recognised by the joint award of the 2007 Nobel Peace Prize to the IPCC. He was elected a Member of the National Academy of Sciences in 2025.
