Near Real-Tim Distribution of LANCE ISS LIS Lightning Data Available at the Global Hydrology Resource Center (GHRC) Distributed Active Archive Center (DAAC)

In February 2017, the Lightning Imaging Sensor (LIS) was launched and installed on the International Space Station (ISS). The highly inclined orbit of the LIS ISS allows for a greater geographic range of measurements than previously measured by the Tropical Rainfall Measuring Mission (TRMM) LIS. The ISS LIS provides total lightning measurements between +/- 55 degrees latitude which includes nearly all global lightning. ISS LIS monitors total global lightning in both day and night and provides important cross-sensor calibration and validation with the Geostationary Lightning Mapper (GLM) and ground-based lightning networks. ISS LIS supplies near real-time (NRT) lightning data over data-sparse regions, such as oceans, to support operational weather forecasting and warning. These near real-time data are available within 2 minutes of observation and are distributed by Land, Atmosphere Near real-time Capability for EOS (LANCE) NRT ISS LIS at the Global Hydrology Resource Center (GHRC) Distributed Active Archive Center (DAAC). The GHRC is a joint venture by NASA Marshall Space Flight Center and the University of Alabama in Huntsville and is one of 12 DAACs across the country. This talk will introduce NASA’s LANCE NRT ISS LIS and the GHRC DAAC, the data, and services they provide. Our presentation will focus heavily on our NRT data distribution. This includes collaborations with operational end users, such as the Aviation Weather Center, National Hurricane Center, Ocean Prediction Center, and Pacific Region as well as field campaigns, such as the HIGH impact Weather lAke sYstem (HIGHWAY). Recent updates and mission status, such as the transition from provisional to validated science data will be included.
