Hi @Pierre, serendipity rules. I happen to want to find out more about remote sensing of soil moisture. This is for 2 friends: one working for an NGO with farmers in sub-Sahara, East Africa and Bangladesh and the other working for the UN on disaster prevention in East Timor where we're interested in landslide probabilities. I've only got as far as having a preliminary browse through some of the MODIS Terra datasets. I'll definitely check out what Blake Pollard did. It would be great if you started a new discussion on the forum if you want to chat more. :)
