SAR data collection over Cyclone Freddy in the Indian Ocean has led to a remarkable collection of imagery. To date, more than twenty eye overpasses have occurred from RADARSAT-2 (3 overpasses), Sentinel 1A (1 overpass) and the three satellites of the RADARSAT Constellation Mission (17(!) overpasses). The animation above shows... Read More
True Color RGB mages — created using Geo2Grid — from GOES-18 (GOES-West), GOES-17 and GOES-16 (GOES-East) (above) displayed the hazy signature of blowing dust associated with a Tehuano wind event, which was spreading south-southwestward from the Gulf of Tehuantepec across the Pacific Ocean on 18 February 2023. A narrow rope cloud... Read More
Sentinel-1A SAR data just before sunrise captured a very narrow region of enhanced winds just south of the Rio Grande delta on 18 February 2023, as shown above in a toggle with the 1226 UTC GOES-16 Band 13 Clean Window infrared (10.3 µm) imagery. There appears to be no obvious... Read More
RADARSAT-2 and RCM-1 had two closely-spaced overpasses over Cyclone Freddy in the Indian Ocean early on 16 February 2023, as shown above. Eyewall speeds exceed 130 knots in the RCM-1 data! (Imagery and data are available here). The quadrant analyses for RCM-1 and for RADARSAT-2 show hurricane-force winds extending out... Read More
