For over the last 40 years, the Japan Meteorological Agency (JMA) has been operating Himawari series geostationary weather satellites covering the Asia-Pacific region. The latest generation of the series is Himawari-8 and -9 launched in 2014 and 2016, respectively. Equipped with the Advanced Himawari Imager, Himawari-8/9 enhances JMA’s weather monitoring and prediction. Himawari-8/9 data are distributed internationally to national meteorological and hydrological services, and the data are also open to academic and nonprofit users.

JMA has undertaken feasibility studies of Himawari-8/9 follow-on satellites. Lightning mappers on geostationary satellites are expected to provide continuous total (intra-cloud and cloud-to-ground) lightning observation. The Geostationary Lightning Mapper (GLM) aboard GOES-R Series satellites is the first operational lightning mapper in geostationary orbit. To assess the GLM performance, this study validates the GOES-16 GLM level 2 product, using ground-based lightning observation data. In this talk, I will provide the GLM product validation results as well as an overview of Himawari-8/9.
