The satellites Terra (launched in 1999) and Aqua (launched in 2002) both carry the Moderate-Resolution Imaging Spectroradiometer (MODIS) instrument, an imager with 26 channels at wavelengths that range from 0.41 µm to 14.1 µm. There are simple ways to create useful imagery with this historical data with Polar2Grid software that... Read More
A major outbreak of severe thunderstorms (SPC Storm Reports) occurred across the Deep South on 12 April 2020. 1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed the development and propagation of deep convection during the 1200-2359 UTC period. The corresponding GOES-16 “Clean” Infrared Window (10.35 µm) images are shown below.Some of the strongest... Read More
CIMSS has long hosted the popular site ‘MODIS Today‘ that allows easy access to full-resolution imagery from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on board Terra (launched in 1999 and still producing imagery) and Aqua (launched in 2002 and still producing imagery). That site remains active and allows access to... Read More
