What can we learn from the Terra satellite?
Data from the satellite helps scientists better understand the spread of pollution around the globe. Studies have used instruments on Terra to examine trends in global carbon monoxide and aerosol pollution. The data collected by Terra will ultimately become a new, 15-year global data set.
What data does Terra provide?
Terra is the first EOS (Earth Observing System) platform and provides global data on the state of the atmosphere, land, and oceans, as well as their interactions with solar radiation and with one another. Altitude: Distance from sea level. Local Node: Approximate time, at the equator when vehicle is directly overhead.
Where can I find processed Terra data?
