NASA LIVE VIDEO PODCAST

Welcome to this highly anticipated episode of the NASA Live Video Podcast: "NASA ARSET: Introducción a NISAR."
In this episode, we explore the groundbreaking upcoming radar mission that is set to revolutionize Earth observation: NISAR (NASA-ISRO Synthetic Aperture Radar). Developed in a historic collaboration between NASA and the Indian Space Research Organisation (ISRO), NISAR is designed to observe and measure some of the planet’s most complex natural processes—from ecosystem disturbances and ice-sheet collapses to natural hazards like earthquakes, tsunamis, volcanoes, and landslides.
Through the lens of NASA’s Applied Remote Sensing Training (ARSET) program, we break down the core foundations of this mission. We discuss how NISAR utilizes advanced dual-frequency (L-band and S-band) Synthetic Aperture Radar to scan Earth's land and ice surfaces globally every 12 days, providing unprecedented, high-resolution data on environmental changes and crustal deformation.
Whether you are an environmental scientist, a GIS and remote sensing specialist, or a space enthusiast eager to learn about the next generation of satellite technology, this episode offers an essential introduction to how NISAR will help us better understand and manage our changing planet.

Welcome to Part 2 of our specialized series on ecological data and remote sensing: "NASA ARSET: Foundations of Species Distribution Modeling with GEE."
In this episode of the NASA Live Video Podcast, we dive deeper into the technical and practical workflows of Species Distribution Modeling (SDM) using the immense computational power of Google Earth Engine (GEE). Building upon our foundational knowledge from Part 1, we explore how scientists utilize NASA’s satellite observations and geospatial datasets to map, predict, and analyze wildlife habitats and biodiversity patterns across the globe.
Join us as we break down the core components of the SDM workflow within GEE. We discuss how to integrate environmental predictors—such as climate data, terrain metrics, and vegetation indices—with species presence data to build robust predictive models. We also address the critical steps of model evaluation, tuning, and understanding the environmental variables that most heavily influence habitat suitability.
Whether you are an ecologist, a GIS professional, a data scientist, or simply fascinated by how satellite technology protects Earth's biodiversity, this episode offers essential insights into modern conservation science.

Welcome to Part 1 of our special deep-dive series on atmospheric science: "NASA ARSET AOD Versus PM2.5 – When They Are and Are Not Related."
In this episode of the NASA Live Video Podcast, we bridge the gap between satellite-based observations and ground-level reality. Aerosol Optical Depth (AOD) from NASA’s Applied Remote Sensing Training (ARSET) program provides a powerful column-integrated view of particles in our atmosphere from space. But how accurately does it reflect PM2.5—the fine particulate matter we actually breathe on the ground?
Join us as we explore the complex relationship between these two critical environmental metrics. We break down the exact scientific conditions where AOD and PM2.5 align perfectly, and more importantly, the meteorological factors—like atmospheric mixing heights and transport layers—where their relationship breaks down completely.
Whether you are an environmental scientist, a data enthusiast, or just curious about how NASA tracks air quality from orbit, this episode offers vital insights into modern satellite data applications.
