The NASA Global Hydrology Resource Center (GHRC) DAAC published the GOES-R PLT Lightning Instrument Package (LIP) dataset. This dataset consists of electrical field measurements of lightning and navigation data collected by the Lightning Instrument Package (LIP) flown aboard a NASA ER-2 high-altitude aircraft during the GOES-R Post Launch Test (PLT) airborne science field campaign. The GOES-R PLT airborne science field campaign took place between March 21 and May 17, 2017 in support of the post-launch product validation of the Advanced Baseline Imager (ABI) and the Geostationary Lightning Mapper (GLM). These data files are available in ASCII format with browse imagery available in PDF format. It should be noted that this dataset is not continuous as flights did not occur every day. Two data files for April 6, 2017 and April 27, 2017 are not included in this dataset due to missing navigation information; however, they are available upon request.
