Project: Direct observation of Earth’s spectral longwave feedback parameter - This project contains the data created for the paper "Direct observation of Earth's spectral longwave feedback parameter". Part of this work was supported by the GRIPS project, funded by NOAA under grant NA20OAR4310375. Summary: The spectral longwave feedback parameter quantifies the change in Earth's spectrally resolved outgoing longwave radiation (OLR) in response to warming. It contains the radiative signature of all longwave feedbacks making it a key quantity influencing Earth's climate sensitivity. By spectrally resolving these changes in OLR, one can gain important information about the underlying feedback processes. This experiment contains spectrally resolved radiative quantities that can be used for the calculation and interpretation of the global mean all-sky spectral longwave feedback parameter based on seasonal and interannual variability, using both satellite observations and simulations. This is an updated version of the experiment. Compared to the first version, this version contains more data on the sensitivity of the spectral longwave feedback parameter on relative humidity changes. Additionally, this version also contains data on the contribution of the surface feedback for different surface temperatures.
