Enhanced Infrared (IR) Imagery (4 km Mercator)
4km Remapped Color Enhanced Infrared Imagery
Current imagery and loops of 4km remapped and color enhanced infrared (IR) imagery is displayed in an earth fixed coordinate system. IR imagery (~11 um) from five geostationary satellites are remapped to a common 4km resolution Mercator projection in an identical manner as the CIRA Tropical Cyclone Image Archive described in (Mueller et al. (2006) . These images are then centered and displayed using the nearest 5 degree latitude/longitude earth coordinate based on the most recent location and past 12-h movement. The images are also color enhanced with the coldest temperatures/highest clouds displayed as colored shades as shown in this color bar.
Geostationary imagery is available from GOES-East and Meteosat Second Generation (MSG; European Space Agency) in the North Atlantic, GOES-West and MTSAT (Japan) in the East Pacific, MTSAT in the West Pacific, and Meteosat-5 (European Space Agency) in the North Indian Ocean, and MSG, Meteosat-5, MTSAT, GOES-W in the Southern Hemisphere tropical cyclone basins.
