SENTINEL-2 SATELLITE

At-home ice checking often begins with a look at MODIS satellite data. “With its sweeping 2,330-km-wide viewing swath, MODIS sees every point on our world every 1-2 days…”

SENTINEL-2 is another satellite that surveys the earth every five days at the equator and every 2-3 days at middle latitudes. SENTINEL-2 is “equipped with an opto-electronic multispectral sensor for surveying with a sentinel-2 resolution of 10 to 60 m in the visible, near infrared (VNIR), and short-wave infrared (SWIR) spectral zones, including 13 spectral channels, which ensures the capture…” 

SENTINEL-2 takes a few more steps than looking at MODIS but the views are well worth the effort.

The 2022 Wisconsin Stern Steering Association regatta has been postponed to February 19 and 20. The next update will be Sunday, February 13. Check back here at that time. The Northwest Ice Yacht Association regatta takes precedence. The prediction changed, not enough melt today, not much expected tomorrow, and the wind dropped quite low for the weekend. Let us know if you find conditions somewhere.
