Overview of the Joint Polar Satellite System (JPSS), NOAA's Proving Ground Initiative on Critical Weather Applications, Numerical Weather Prediction (NWP) Impact Studies and Data Assimilation

The JPSS Proving Ground and Risk Reduction (PGRR) program supports user demonstration by stimulating interactions between technical experts from the JPSS Program, university partners, and key user stakeholders. The PGRR has strategically invested in multiple projects to maximize the benefits of the use of current JPSS capabilities and identify new ways of using JPSS data operationally. The PGRR Program projects are grouped into initiatives, one of which is the Critical Weather, NWP and Data Assimilation Initiative. The main purpose of this initiative is to further the scientific advancement of the use of JPSS satellite data to support critical weather forecasting and numerical modeling efforts in NOAA and beyond. This presentation provides an overview of the 9 different projects that are participating in this initiative including their research updates, collaboration to bridge research operation to development of products and user engagement. The participating project’s research area ranges from improvement of tropical cyclone forecast capabilities using JPSS data suite, satellite based hurricane intensity estimation in JPSS/GOES-R era to NPP & JPSS data assimilation improvements, CrIS radiance assimilation in GSI for better forecasts of high impact weather events etc.
