Using a combined LEO/GEO approach, ABI and VIIRS retrievals are used to estimate flooding from a satellite perspective. Individual flood products from VIIRS and ABI (or AHI, depending on location) are blended to create the NOAA LEO/GEO Flood Mapping Product.An example is shown below over the... Read More

Auckland, on the North Island of New Zealand, has experienced significant flooding starting on 27 January 2023. MIMIC Total Precipitable Water fields, above, (from this site, or downloadable here) show an atmospheric connection between the deep tropical moisture that is persistent between 5oS and 20oS; a filament moves with a cyclonic swirl from 26-28 January. A second region of... Read More
