Software Release: Containerized NWP System Version 4.0.0 Release

The Developmental Testbed Center (DTC) is pleased to announce the release of version 4.0.0 of their end-to-end containerized numerical weather prediction (NWP) system. These software containers have been established for community use to quickly spin up an NWP forecast system [using the WRF Pre-Processing System (WPS), Weather Research and Forecasting (WRF) model, and Gridpoint Statistical Interpolation (GSI) data assimilation] that can then be post-processed [using the Unified Post Processor (UPP)] and verified [using the Model Evaluation Tools (MET)], with plotting capabilities providing using Python.

You can learn more about running this system using either Docker or Singularity containers on a hard-iron machine or on the cloud using Amazon Web Services (AWS) by working through our Online Tutorial.
