GHRC DAAC is pleased to announce the public “beta” release of near real-time data from the Lightning Imaging Sensor (LIS) on the International Space Station (ISS). Lightning observations and background data files are generated within minutes of observation. A browse web page (lightning.nsstc.nasa.gov/isslisib/isslisnrt.html) shows the most recent two minutes of lightning data on a map, along with composite image showing lightning observations for the past 12 hours. The two LIS (ISS) datasets are:
- Near Real-Time (NRT) LIS (ISS) Science Data
- NRT LIS (ISS) Backgrounds
GHRC DAAC published beta versions of the Lightning Imaging Sensor on the International Space Station - LIS (ISS) non-quality-controlled standard products on September 17. These data are made available to users until a manual quality control process is complete, at which time they will be replaced by the archive version of the products.
- Beta Non-Quality Controlled LIS (ISS) Science Data
- Beta Non-Quality Controlled LIS (ISS) Backgrounds
These data are collected by the LIS (ISS) used to detect the distribution and variability of total lightning occurring in the Earth’s tropical and subtropical regions. These data can be used for severe storm detection and analysis, as well as for lightning-atmosphere interaction studies. The LIS instrument makes measurements during both day and night with high detection efficiency. The data are available in both Hierarchical Data Format 4 (HDF4) and Network Common Data Form 4 (netCDF-4) formats. Data is available from 3/1/2017 forward.
