Watching the Sun: 45 years of satellite data (Video)


CERES co-team leader, Dr. Ronan Connolly, has just launched his own YouTube channel, @RonanConnollyScience. His first video describes the paper we posted about yesterday. We have also uploaded the video to the CERES YouTube channel. If you'd like to learn more of our research, please subscribe to both channels:

In this video, Dr. Ronan Connolly describes our latest paper on the Total Solar Irradiance (TSI) measurements in the satellite era, 1978-present. TSI represents the amount of energy reaching the Earth from the Sun.


Scientists have been debating what trends, if any, there have been in TSI since the first TSI satellites were launched in 1978. Some scientists have claimed that there has been almost no long-term changes other than an 11-year up-and-down cycle tracking the sunspot cycles. Others have suggested that there have been additional multi-decade-long TSI trends between each cycle.


Here, Ronan digs into these debates and presents the new results that will change our understanding of this ongoing scientific mystery.
