His comments:<br /><br />"It's only a secret, because it hasn't yet been run through all the operational paces yet. Everyone is really excited about the DNB on the VIIRS sensor. Day-night band is sensitive from green to near infrared. Last summer I had a briefing from some scientists about how they can discern completely unexpected things like ground fog and marine layer clouds.<br /><br />P.S. GINA receives what we call the HRD (high rate data) link on X-band (7.5 GHz). HRD is real-time imagery broadcast to stations on the ground kind of like the AVHRR/HRPT from the polar-orbiting weather satellites (which come down on L-band, or 1.7 GHz). If you go to GINA's Swathviewer application (http://sv.gina.alaska.edu) you can see data from many other spacecraft.

The Aurora can limit that process if active via increased signal absorption.<br /><br />Now to compare that link with these:<br /><br />http://www.swpc.noaa.gov/pmap/index.html<br />http://helios.swpc.noaa.gov/ovation/<br />http://www.gi.alaska.edu/AuroraForecast<br /><br />GaryNL7Yhttps://www.blogger.com/profile/15874712728971005352noreply@blogger.com
