There are many GOES loops showing the moon’s shadow from the total solar eclipse on April 8, 2024 (UW/CIMSS; CIRA; Satellite Liaison; NOAA). Time compositing, in this case selecting the minimum brightness, shows the shadow from several times in a single frame.2017 and 2024 ComparisonsThe size of the Moon’s shadow on... Read More
10-minute JMA Himawari-9 AHI Infrared Window (10.4 µm) images (above) showed an explosive eruption of Mount Ruang in Indonesia on 17 April 2024. Note that a thunderstorm was reported at Menado (station identifier WAMM) from 1400-1430 UTC, due to abundant lightning activity within the dense volcanic umbrella cloud.In the Himawari-9 Infrared Window...

1-minute Mesoscale Domain Sector GOES-18 (GOES-West) “Clean” Infrared Window (10.3 µm) images with an overlay of the Total Precipitable Water derived product (in non-cloudy areas) (above) showed that an axis of moisture was initially in place across all the Samoan Islands — peak TPW values were in excess of 2.0 in (brighter shades of magenta). The axis of... Read More
A sequence of Suomi-NPP VIIRS Visible (0.64) images (above) displayed the cyclonically-curved cloud structure associated with an Arctic low pressure system (surface analyses) located between Alaska and the North Pole on 14 April 2024. A blend of Atmospheric Motion Vectors derived from NOAA-20 and NOAA-21 (below) showed the flow pattern at... Read More
