1． Introduction
This user’s manual explains how to use the tool for “RSP Path Detection in L2 Tile of
GCOM-C/SGLI HDF5 products”. This tool detects the number of RSP-path for raster
data in the L2-tiles on a daily basis (01D) based on the observing time and attaches it
to the original filename. If the tile includes multiple RSP paths, the tool separates the
tile for each of the paths and outputs their corresponding multiple HDF5 files. The type
of tool is CUI (Character User Interface) so that users can install it into their system or
scripts for mass processing.
2． System Requirements

． Input Products / Available Datasets
Available input SGLI HDF5 products for this tool are L2-tiles on a daily basis (01D) as
follows:
LTOA, RSRF, VGI, LAI, AGB, LST, CLFG, CLPR, ARNP, ARPL, SICE, SIPR
The tool uses the following dataset, which indicates the observing time of all raster
data in the tile, for detecting the number of RSP-path.
Geometry_data/Obs_time
The following products do not include the above dataset; therefore, the tool needs an
additional input of the LTOA or RSRF product that has the same Granule ID as a
reference.
VGI, LAI, AGB, SICE, SIPR
