Data Pool

Data Pool allows quick access to recently processed data. Use the MISR order tool to obtain ALL data products.

The ASDC is currently in the process of converting to an online archive. At completion, all publicly available MISR data should be online in the Data Pool.

Tools available from ASDC to work with MISR Data

• MISR orbits the earth 15 times/day.

• Orbit numbers indicate the number of revolutions since launch.

• 233 distinct orbit paths repeat every 16 days.

• Each of these 16 days is referred to as a Data Day.

• Each path is divided into 180 blocks.

• Paths overlap, allowing near global coverage in 9 days.
