What is the geographic coverage of MISR?

The MISR instrument continuously acquires data everywhere on Earth, but with a frequency that is dependent on the latitude of the location of interest. Indeed, due to the overlap of the swathes near the poles and their wide separations at the equator, repeat coverage varies from 2 to 9 days, respectively.
