Title: "Estimating Short-term Cloud Radiative Feedback from A-Train"

Abstract: Cloud radiative feedback (cloud feedback) has been identified as the major source of inter-model spread on climate sensitivity and future climate projections in response to increased greenhouse gases. Recent studies show the short-term cloud feedback estimates are highly correlated with their long-term counterparts (e.g. Zhou et al. 2015, Colman and Hansen 2016, Yue et al. 2016). Therefore, it is plausible to use the short-term cloud feedback calculated from satellite observations to constrain the model-based results and understand the cloud feedback mechanisms. However, the short-term cloud feedback estimated from satellite observations suffers from very large uncertainties and weak signals, which are due to the uncertainty on the cloud and radiative flux observations, and the compensation from different cloud types, regions, and altitudes where cloud change occurs as a response to climate variations. In the current study, we estimate the short-term cloud feedbacks by cloud type as well as their uncertainties from A-Train using the observation-based cloud radiative kernel (CRK) method (Yue et al. 2016). The multi-sensor observations obtained from A-Train satellites have been collocated at the pixel scale to derive both the CRKs and the cloud cover response (Yue et al. 2016) to maintain the consistency between radiative kernels and climate responses.
