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
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

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

Meeting Brazil’s needs for remote sensing Today - We monitor Amazônia with 250
meters resolution every day
In 2009, Brazil will have the capacity to monitor Amazonia and the entire Earth with 50 meters resolution every 2 days
