Comments on: Why does the Earth Observatory show some floods and not others? http://earthobservatory.nasa.gov/blogs/earthmatters/2011/06/21/why-does-the-earth-observatory-show-some-floods-and-not-others/?src=earthmatters-rss Earth is an amazing planet, and the one that matters most to us. Let’s have a conversation about it.

They’ve been plagued by cloudy weather for much of the last couple of weeks (very much related to the cause of the flooding!).

Your article is informative as it points to the importance of Earth observation for flood assessments. Part of the arsenal of useful sensors are a fleet of imaging radar satellites which are worth mention. Synthetic aperture radar, or SAR, sensors aboard the European Envisat and the Canadian RADARSAT satellites, as well as others, have been hugely successful for many years now. A good example of US-Canadian cooperation was recently portrayed at

(see Item 9 > Richelieu River flood). There are many more examples of optical and radar applications for flood monitoring efforts around the world. US sensors of the optical kind are often an essential component. Yet, satellite radars are equally effective and very reliable tools, especially at the regional scale level. Yes, we CAN see through the clouds! Besides satellite SAR and optical sensor technology, cooperation and coordination are important keys to successful flood monitoring.
