Tropical Storm Bolaven has formed in the western Pacific and is moving towards the Marianas Islands. Were there satellite products useful in monitoring the atmosphere prior to the storm’s development? One such useful product is the Advanced Scatterometer (ASCAT) that is on both MetopB and MetopC polar orbiters at this website (or this one). The stepped animation above, from... Read More
RADARSAT-2 and RCM-3 satellites had nearly simultaneous overpasses over Typhoon Koinu on 3 October 2023, as shown below. (See this blog post from 2 October for more on Koinu) Both SAR analyses showed the strongest winds (nearly 120 knots) in the southern eyewall of the storm, with long interesting wind minima features...

Target Sector (2.5-minute interval) JMA Himawari-9 AHI Visible and Infrared images (above) showed Typhoon Koina as it intensfied to a Category 3 storm by 0000 UTC on 02 October 2023 (SATCON). Cloud-top infrared brightness temperatures were as cold as -90C.Just prior to the start of the Himawari-9 animation, an image of RCM-3 Synthetic Aperture Radar (SAR) winds... Read More
Sentinel-1A overflew the country of Savai’i and the south Pacific to its south on 1 October 2023 (Click here to view the scene at the OceanDataLab website; data are also available at NOAA/STAR’s SAR data website). A benefit of the SAR data is its remarkable horizontal resolution, manifest above as very narrow regions of... Read More
