Conventions

All data generated by the satmo system follow a strict naming convention and are organized in directories accordingly. Util functions are available in the API (e.g.: filename_parser()) to parse information from these file names, to generate file names from metadata (filename_builder()), or to build the path corresponding to a given file (path_builder()).

In most functions and command lines, a variable data_root=, corresponding to the root of the directory tree has to be set. The directories are then organized as follows:

sensor
├── L1A
│   └── year
│       └── doy
├── L2
│   └── year
│       └── doy
├── L2m
│   └── year
│       └── doy
├── L3b
│   └── year
│       └── doy
└── L3m
    ├── 8DAY
    │   └── year
    │       └── doy
    ├── DAY
    │   └── year
    │       └── doy
    └── MO
        └── year
            └── doy

The table below provides examples of filenames and associated location for different data levels.
