This study aims to quantify the portion of the Earth's outgoing radiation that is attributable to tropical cyclones (TCs). To accomplish this, we have developed a method that starts with an image processing algorithm which labels cloud pixels associated with a TC, based on the time series of brightness temperature images and best-track data. The labels attributable to the TC are then combined with radiation data to obtain the TC-related radiation throughout its lifetime. Preliminary results are shown for the North Atlantic Ocean in 2012 and 2013: In 2012, the average TC shortwave and longwave radiation contributed 0.039 PW (or 0.35%) and 0.099 PW (or 0.34%), respectively, to the total regional radiation; In 2013, the contribution due tot TCs decreased to 0.022 PW (or 0.19%) for SW, and 0.059 PW (or 0.20%) for LW radiation.
