Combine multiple products from files or directories by appending them across the time dimension and storing the result into a single output file.
Usage: harpmerge [options] <file|dir> [<file|dir> ...] <output product file> Concatenate all products as specified by the file and directory paths into a single product. If a directory is specified then all files (recursively) from that directory are included. If a file is a .pth file then the file paths from that text file (one per line) are included. These file paths can be absolute or relative and can point to files, directories, or other .pth files. Options: -a, --operations <operation list> List of operations to apply to each product. An operation list needs to be provided as a single expression. See the 'operations' section of the HARP documentation for more details. Operations will be performed before a product is appended. -ap, --post-operations <operation list> List of operations to apply to the merged product. An operation list needs to be provided as a single expression. See the 'operations' section of the HARP documentation for more details. -o, --options <option list> List of options to pass to the ingestion module. Only applicable if an input product is not in HARP format. Options are separated by semi-colons. Each option consists of an <option name>=<value> pair. An option list needs to be provided as a single expression. -l, --list Print to stdout each filename that is currently being merged. -f, --format <format> Output format: netcdf (default) hdf4 hdf5 --hdf5-compression <level> Set data compression level for storing in HDF5 format. 0=disabled, 1=low, ..., 9=high. --no-history Do not update the global history attribute. If the merged product is empty, a warning will be printed and the tool will return with exit code 2 (without writing a file). harpmerge -h, --help Show help (this text). harpmerge -v, --version Print the version number of HARP and exit.
