AMS2023 2nd Symposium on Community Modeling and Innovation

AMS2023 2nd Symposium on Community Modeling and Innovation


EPIC is pleased to announce its two hands-on workshops scheduled for January 8, 2023, at the 103rd American Meteorological Society (AMS) Annual Meeting. The workshop topics are:

  • Earth Prediction Innovation Center (EPIC) Workshop: Running the Unified Forecast System (UFS) Short-Range Weather (SRW) Application in the Cloud
  • Earth Prediction Innovation Center (EPIC) Workshop: Building the SRW Application in Containers and on Bare-Metal Systems. 

The Annual Meeting provides a forum for the community to share ideas and experiences on the research and development of Earth system models and their applications in operational forecasting. It also welcomes abstracts discussing how community models can serve as educational resources in the classroom. The Annual Meeting will take place January 8-12, 2023, in Denver, CO and online.

In-person and remote registration rates are available on the Annual Meeting registration page:

EPIC’s Short Course at AMS

Earth Prediction Innovation Center (EPIC) Workshop:

Running the Unified Forecast System (UFS) Short-Range Weather (SRW) Application in the Cloud

Sunday, January 8, 2023, from 8:00am – 12pm MT

This short course will teach students how to configure and run the UFS SRW Application on the Amazon Web Service (AWS) cloud computing platform. The UFS SRW App is a numerical weather prediction framework that targets predictions of atmospheric behavior on a limited spatial domain and on time scales from less than an hour out to several days. It is a convection-allowing ensemble-enabled forecast system designed to improve NOAA’s predictions of hazardous convective storms. The application unites the essential components of the UFS regional modeling system under a single umbrella repository structure. Components include the Finite-Volume Cubed (FV3) based prognostic UFS Weather Model, pre- and post-processing code, verification, and a workflow for running the system end-to-end. The App is designed to be used by both researchers and in operations.

Earth Prediction Innovation Center (EPIC) Workshop:

Building the SRW Application in Containers and on Bare-Metal Systems

Sunday, January 8, 2023, from 2:00pm – 3:45pm MT

This workshop will focus on how to build the SRW Application starting with a Singularity container that has the SRW App source code and spack-stack software libraries pre-installed. If time permits, there will also be a discussion of how to build the spack-stack without a container.

Registration for this workshop coming soon.


The following abstracts from The EPIC Team were accepted for submission:


The Hierarchical Testing Framework for the UFS

by Yi-Cheng Teng & Stelios Flampouris

Hierarchical testing image temporary

The main goal of this work is to develop a transparent and approachable prototype framework for UFS community testing of the UFS weather model and its components consistent with the HSD (Hierarchical Systems Development) approach and NOAA baseline operational metrics, that can be easily used by the community.

Cloud Benchmarking of the Noncoupled Atmospheric UFS-Weather Model

by Zach Shrader

Cloud Benchmarking image - temporary

This abstract summarizes the benchmarking experiments of the UFS Weather Model on NOAA RDHPC systems and the three main Cloud Solution Providers (AWS, GCP and Azure). Using the wall time averages of repeated test runs, the performance of the UFS Weather Model was assessed in terms of cost analysis, scalability, and run-time variability.
