    The GOSAT Tools are designed for GOSAT data users to select CAI products and to extract datasets from FTS products already downloaded to each user’s computer.

    GOSAT Tools contain CAI Copier and FTS Exporter.

  • CAI Copier
  • If you specify the search conditions (observation period, path, and area), and input/output directories on your computer, CAI Copier copies the CAI product files matching the search condition from the input directory, which contains already downloaded CAI products, to the output directory. Available types of product are CAI Level 1B/1B+ (L1B/L1B+), and Level 2 (L2).

  • FTS Exporter
  • If you specify the search conditions (observation period, path, and area), product (type and dataset), and input directory/output file on your computer, FTS exporter exports the datasets from already downloaded FTS products in the input directory to the output file in CSV format.
    Available types of product are FTS Level 2 (L2).

    Please refer to the Operation Manual, first.

    If you want to get these tools, please apply by e-mail to [support email address] with the following information: name, job, nationality, affiliation (organization name, department, postal code and address of the organization), contact phone number, e-mail, purpose of use and kinds of package (Please select one of the following 4 kinds.).

    2. Please un-compress the downloaded file and save "read_gosat.sav" in "save_add" directory in "ENVI" directory. If "read_gosat.sav" was already stored in the directory, please overwrite it after saving it for your own back-up.

      "ENVI" directory means as follows for the default installation;

      • [ENVI 4.8]
      • Windows : C:/Program Files/ITT/IDL/IDL80/products/envi48
      • Linux : /usr/local/itt/idl/idl80/products/envi
      • Macintosh : /Applications/itt/idl/idl80/products/envi

      • [ENVI 5.0]
      • Windows : C:/Program Files/Exelis/ENVI50/classic/
      • Linux : /usr/local/exelis/envi50/classic
      • Macintosh : /applications/exelis/envi50/classic

      • [ENVI 5.1]
      • Windows : C:/Program Files/Exelis/ENVI51/classic/
      • Linux : /usr/local/exelis/envi51/classic
      • Macintosh : /applications/exelis/envi51/classic

    3. Please store "usradd.txt" file in "menu" directory after saving "useradd.txt" in "menu" directory in "ENVI" directory for your own backup.

    4. Please restart ENVI with "Classic Mode" and you will see "GOSAT" in the pull down menu to select "File" -> "Open External File" for reading CAI products of HDF.
