The 10th and final special RADARSAT-2 data collection of SAR winds over the Guam Area of Responsibility (AOR) occurred on 24 November, and is shown above in a toggle with the Himawari-8 Clean Window imagery at the same time (Here is the same toggle as above but with SAR data... Read More

RADARSAT-2 observations of SAR data near/around the island of Guam in the Marianas Islands continue in November (as previously discussed here, here and here). Overpasses on 15 November (above) and 17 November (below) contain features that deserve comment. For example, there is an obvious seam (and a less-obvious second seam)... Read More

RADARSAT-2 overflew Guam early on 10 November 2022, and the toggle above shows both Himawari-8 imagery at that time with the SAR wind estimates overlain. This was a time of light winds and minimal shower activity. It’s interesting that the wake of weak winds downwind of the islands of Guam... Read More

Synthetic Aperture Radar (SAR) data retrievals continue over Guam, with 10 planned for November. The toggle above compares the 2009 UTC SAR footprint (from RADARSAT-2) with Himawari-8 Clean Window (10.41) infrared imagery at 2010 UTC (on 5 November 2022). These data are also available online at this NOAA/STAR Website; there are also... Read More
