Dataset Descriptions & Ordering Information

[Dataset Information]

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.

LIS/OTD Gridded Data
LIS Data
OTD Data

Long Range Cloud to Ground Data
NLDN Cloud to Ground Data
KSC LDAR Data
TRMM LBA Data

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.

Ordering Data Information

Data can be ordered free of charge from the GHRC through HyDRO, the GHRC's online data ordering system, or by contacting the GHRC User Services Office. Please note that not all datasets archived by the GHRC are from the Lightning Team. Most datasets are available in several media forms, including digital tape and FTP download, and are available in compressed or uncompressed formats. Most datasets are stored in HDF (Hierarchical Data Format) files. Information about this format is available from the National Center for Supercomputing Applications (NCSA) at the URL http://hdf.ncsa.uiuc.edu/. NCSA provides a public domain library supporting HDF on a wide variety of computer platforms.
