Dataset Descriptions and Ordering 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 Climatology Data
TRMM LBA Data
LIS Data
OTD Data
NLDN Cloud to Ground Data
Long Range Cloud to Ground Data
LDAR Data From KSC
KSC Field Mill Data
DC LMA Browse
North Alabama LMA Browse
Lightning Nitrogen Oxides Model Data
Hydro Data Search Engine

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.

  LIS/OTD Climatology Data
Folder  
The LIS/OTD Climatology data sets consist of gridded climatologies of total lightning flash rates seen by the spaceborne Optical Transient Detector (OTD) and Lightning Imaging Sensor (LIS).

  TRMM LBA Lightning Instrument Package Data
 
Folder blank_spacer The TRMM LBA Lightning Data includes field mill data, conductivity probe temperatures from two probes, and navigation data. They were collected during the Tropical Rainfall Measuring Mission (TRMM) in north west Brazil (Rondonia), from Jan 23 - Feb 14, 1999.

  Lightning Imaging Sensor (LIS)
       
Folder blank_spacer LIS is a space-based sensor which is being used to detect lightning activity in the tropics. It was launched into a low earth orbit on November 1997 as part of the TRMM mission.

  Optical Transient Detector (OTD)
       
Folder blank_spacer OTD is a space-based sensor which has been used to determine the distribution of lightning activity around the globe. It was launched into low earth orbit on April 1995 on the Orbview-1 (formerly Microlab-1) spacecraft. The OTD Mission ended March 23, 2000.

  National Lightning Detection Network (NLDN)
       
Folder blank_spacer The NLDN is a ground-based lightning detection network for the continental United States that is used to detect cloud-to-ground lightning. These data are restricted to collaborators that have a working relationship with the NASA Marshall Space Flight Center (MSFC) Lightning Group.

  Long Range Lightning Network
       
Folder blank_spacer A ground-based lightning detection network that is used to detect lightning over the Atlantic & Pacific oceans up to 1200 miles during the day and 2500 miles at night beyond the continental United States. Data are available from July, 1996 to November, 2003. These data are restricted to collaborators that have a working relationship with the NASA Marshall Space Flight Center (MSFC) Lightning Group.

  Lightning Nitrogen Oxides Model (LNOM) Data
       
Folder blank_spacer The Lightning Nitrogen Oxides Model (LNOM) data is presently available for two regions: North Alabama and the District of Columbia. The LNOM datasets are restricted to those who appear on the LNOM Users List (LUL). Only those investigators that have a working relationship with the NASA Marshall Space Flight Center (MSFC) Lightning Group on topics directly pertaining to global chemistry/climate analyses, regional air quality, or other areas directly related to lightning chemistry are allowed access to the LNOM data. Redistribution of LNOM data is prohibited.

  KSC LDAR
       
Folder blank_spacer A type of lightning detection instrumentation that is used to detect both intracloud and cloud-to-ground lightning near the Kennedy Space Center in Florida. ldarraw starts on 1997.059 (Feb. 28, 1997) and ends on 2008.163 (June 11, 2008).

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.
