How do I order MISR data?

MISR data are processed and archived at the NASA Langley Research Center Atmospheric Science Data Center (ASDC). A MISR Order and Customization Tool is available that enables users to order and customize data in a single interface. Some features are non-consecutive path and orbit search; and sorting search results by date, camera, path, orbit, and file version. Customization options are subsetting by parameter, block, and spatial coordinates; additional latitude and longitude layers, and unpacking and unscaling applicable fields; and output data in HDF-EOS stacked-block grid or conventional grid. The reformatting option, referred to as "Conventional HDF-EOS", is designed to be an easier-to-use alternative to MISR's stacked-block format. The interface currently supports two output formats:

  1. Stacked-block HDF-EOS (original file format)
  2. Conventional HDF-EOS grid

See FAQ on Customizing and Subsetting MISR products for more information.

MISR data are also available through the ASDC Data Pool (an on-line, short-term data cache that provides a Web interface and FTP access). Specially subsetted and/or reformatted MISR data products supporting field campaigns are also available. Passive FTP mode is required to access the Data Pool from the command line as "ftp -p l4ftl01.larc.nasa.gov", where the system translates to "lower case L four ft lower case L zero one .larc.nasa.gov". A UNIX C shell script method may be used to assist in downloading files from the Data Pool (Readme | Sample script). Data files are stored in directories based on data product and acquisition date. Corresponding metadata files are available in Extensible Markup Language (XML) format.

Another method to obtain MISR data is through the Earthdata Search Tool. Tutorials for this ordering tool are available.
