Re: How do I know if MISR data are available for my location and time of interest?

MISR observes the entire day-lit side of each orbit. The MISR Production Report allows you to determine what data are available for an orbit range, a date range, or a path range. To obtain an inventory of MISR archive holdings for a specific location or time, submit a query through the MISR Order an...

Re: How large are the MISR data files?

Depending on the MISR data product, the files can be quite large (for example, a Level 2 Aerosol data product file is approximately 35 Megabytes and a Level 1B2 Radiance file is approximately 600 Megabytes).

Re: How are MISR science data products generated?

MISR data products are grouped into three processing Levels. Level 1 processing provides corrected (or calibrated) instrument data. These data are processed and calibrated to remove many of the instrument effects. The resulting products thus contain minimal instrument or spacecraft artifacts and are...
