How do scientists make sure our weather radars are actually accurate? In this episode, climatologist Dr. Irene Crisologo explains how she used satellite data to calibrate ground-based weather radars in the Philippines and overcoming challenges like beam blockage from mountains and urban structures. We also trace her journey from physics to geology and climatology, and how she turned her love for drawing into science communication. #RadarScience #ClimatePH #ScienceCommunication #PinoyScientist ⌛Chapters 00:00 Radar and Satellite Analysis of Rain 00:50 Podcast and Partners Introduction 04:00 Meet Our Guest 09:35 Moving from Physics to Geology and Climatology 13:20 Developing Radar Research and Science Communication 19:53 Understanding Beam Blockage and Radar Measurements 28:49 Introduction to Dr. Irene's Research 32:40 Analysis of Rain Measuring Instruments 34:44 Importance of Calibration in Radar Data 42:02 Analysis and Calibration Methods 48:49 Data Access and Research Challenges 52:31 Research and Analysis Experiences 58:06 Tips for Beginning Researchers 📚Reference: Crisologo, I., Warren, R.
