MODIS Thermal Infrared Sounding (MOTIS): Estimating Tropical Cyclone Central Pressure from Warm-Core Anomalies

Announce Type: new Abstract: This study presents a novel framework for estimating the central sea-level pressure ($P_{\rm c}$) of tropical cyclones (TCs) using infrared radiometers. We leverage the long-overlooked combination of high spatial resolution and sounding capability of the Moderate Resolution Imaging Spectroradiometer (MODIS) to measure warm-core anomalies in TC eyes. We develop the MODIS Thermal Infrared Sounding (MOTIS) framework, which performs instrument-specific preprocessing...

NASA satellites reveal major ocean nutrient stress

NASA satellites reveal major ocean nutrient stress Lisa Lock Scientific Editor Robert Egan Associate Editor A new study combining NASA satellite observations, ocean surveys and genetic testing of marine microorganisms found evidence that warming ocean waters may be limiting nutrient availability across much of the global ocean. The researchers report that this nutrient stress affects microscopic marine organisms and could influence marine ecosystems over time. The research, published June 5...
