The data collected by Lightning Team instruments is archived and cataloged by the Global Hydrology Resource Center where it is made available free of charge (see below) . Some datasets also have additional software packages available. Information on these software packages is in the documentation provided by the GHRC.

NOTE: Most data sets have browse images which are created as soon as possible after initial data ingest. As time allows, quality control procedures are performed, especially on satellite datasets. QC refers to data which has been through quality control procedures, while Non QC refers to "non quality controlled" for which only the browse images have been generated. Where possible, we have provided both.
