This question is being submitted on behalf of a user:

I have download the data you offered for me (MIL2ASAE product). But I can't understand how to use this data with multi band in the hdf. Could you send me a detailed document about how to use this data? Thank you.

  1. Thanks for your interest in MISR.  

    There is considerable documentation on the content of the MISR HDF data files.  A good place to start is with the MISR Data Product Specification (DPS) document, available from https://eosweb.larc.nasa.gov/project/misr/dps.  This list all the data fields, formats, expected values, etc.  For DPS Revision S (i.e., the current one), the MISR Level 2 Aerosol/Surface Product material begins on p. 153.

    "Using" the data is another matter.  This depends a great deal on what question(s) you are trying to answer.  The fundamental explanations of the underlying algorithms are given in the Algorithm Theoretical Basis Documents (ATBDs), available from https://eospso.gsfc.nasa.gov/atbd-category/45.  For practical application ideas, it is probably best to look at previous scientific publications in peer-reviewed journals; for MISR, much of the published research is cited, and in some cased posted, here: https://misr.jpl.nasa.gov/publications/peerReviewed/

    If you are having technical difficulties downloading or opening the MISR data files, there is more information on the NASA Langley Atmospheric Sciences Data Center (ASDC) web site, here: https://eosweb.larc.nasa.gov/project/misr/misr_table, and as a last resort, the ASDC Support Team are experts on helping users with questions regarding MISR data handling (support-asdc@earthdata.nasa.gov).  

     

    Be well.  Ralph Kahn (MISR Aerosol Scientist)

     

  2. Ralph has answered your query very thoroughly but you might like to check the tools that have been made available to work with MISR data sets at ASDC: https://eosweb.larc.nasa.gov/tools/  (scroll down and click on 'MISR and AirMISR Tools'). There are also routines developed for use with the MISR Toolkit for various purposes (unpacking, reprojecting to user-define grids, reformatting) that might be useful; let us know.
