2. The need for global land observation The world is changing rapidly  Climate Change is here to stay Global land observation is a crucial need for the world, but its future is uncertain  MODIS is very useful,but has no future  What will happen to LANDSAT? Global land observation systems are a public good

3. The need for fast monitoring of change Protecting the Amazonian rain forest Annual wall-to-wall detailed survey  Uses LANDSAT-class satellites Daily monitoring of new deforestations  Uses MODIS-class satellites

14. Rationale for Brasil’s SSR-1 satellite Brazil needs satellites with fast revisit for real time deforestation detection We currently use MODIS (daily revisit) but need a better spatial resolution The AWFI (advanced wide field imager) sensor in CBERS-3 has 60 meter resolution every 5 days SSR-1 will have a AWFI with 40 meter resolution every 5 days With the AWFIs of CBERS-3 and SSR-1, we will cover Amazônia every 2 days
