NASA SPoRT prepares for the Geostationary Lightning Mapper
In 2009, the SPoRT program developed the pseudo geostationary lightning mapper (PGLM) flash extent product to serve as a demonstration for what forecasters may see once the GLM is launched. Developed from total lightning data from four ground-based networks (North Alabama, Kennedy Space Center, Oklahoma, and Washington D.C.), this product was used operationally during the 2010 Spring Program. This presentation will address the feedback received during the Spring Program and SPoRT's continuing efforts to evaluate this product to help improve the transition of the AWG's official GLM proxy. In addition, this will discuss a new lightning trend product that can be applied to the PGLM and future AWG proxy.
In addition to real-time GLM demonstration products, the Spring Program received the lightning threat algorithm for use in the National Severe Storm Laboratory's WRF model. This algorithm was used operationally during the 2010 Spring Program and uses graupel flux and vertically integrated ice to forecast where and when lightning will occur. The ultimate goal of this project will be to incorporate GLM data as an input data set in numerical modeling once GOES-R is launched.
