Bridges to Operations: METplus in Operations

Autumn 2023 | During the first few years of the DTC, the United States Air Force (USAF) put forth a vision for the DTC to develop a suite for verification tools that would provide reproducible results such that statistics and metrics could be shared across institutions.  The USAF envisioned a suite of tools that would include both standard verification approaches, as well as advanced diagnostic methodologies.  In 2008, the DTC released the software package, Model Evaluation Tools (MET) to the… Read More

Visitors: Cristiana Stan and Loren Doyle

Autumn 2023 | Cristiana Stan of George Mason University originally proposed a very exciting and new type of DTC visitor project that involved holding a “hack-a-thon” where teams of two graduate students would be tasked with selecting and developing a METplus Use Case for one of the subseasonal to seasonal (S2S) metrics identified during the 2021 DTC UFS Evaluation Metrics Workshop.  The winning team would then be given the opportunity to visit the DTC for up to three months to collaborate with the… Read More

Lead Story: NOAA’s New Fire Weather Testbed and DTC Fire Weather Verification

Autumn 2023 | With wildfires increasingly impacting society and ecosystems spanning local to global scales, NOAA has expanded its strategic investments and plans to address wildfire-related hazards. In 2023, NOAA established a new Fire Weather Testbed (FWT), Read More

Director's Corner: Dr. Steven Lack and Dr. Bonnie Brown

Autumn 2023 | The U.S. Air Force’s partnership with the DTC dates back to 2003 and one of the main areas of collaboration has been the advancement of scientific and technical research into a community-backed set of tools for model verification known as Model Evaluation Tools (MET) and its subsequent evolution into the METplus suite of tools. The USAF has provided financial as well as in-kind participation in governance to the DTC and in return benefits from the expansion of this tool set across many… Read More

Who's Who: Dustin Swales

Autumn 2023 | Dustin Swales works for NOAA-GSL where his primary role is leading the development of the CCPP Framework, the physics coupling infrastructure used by NOAA UFS applications. The Framework is used by a wide range of users beyond NOAA, and so a significant piece of this role requires working closely with collaborators at NCAR to develop this Framework across modeling applications. Tangential to this, he works on CCPP Physics development, the physical parameterizations enabled by the… Read More

Community Connections: The Common Community Physics Package (CCPP) Visioning Workshop

Autumn 2023 | The Common Community Physics Package (CCPP) Visioning Workshop, which took place virtually on August 15-17 of 2023, convened discussions focused on the current status and future direction of the CCPP. The workshop was organized by a multi-institutional committee composed of representatives from DTC (Grant Firl, Lulin Xue, Dustin Swales, Ligia Bernardet), NCAR’s Mesoscale and Microscale Meteorology (Laura Fowler) and Climate and Global Dynamics (Courtney Peverley) Laboratories,… Read More

PROUD Award - Excellence in Action: GRANT FIRL, Research Scientist II, CSU/CIRA at NOAA GSL & DTC

Performance Recognition for OUtstanding DTC achievements (PROUD) Award

2023-11-28 | Grant Firl is a Research Scientist II (more specifically, an Atmospheric Physics Development and Implementation Research Scientist) with the CSU/CIRA at NOAA GSL, contributing to the Common Community Physics Package (CCPP) project at the DTC. Grant was the foundational developer of the CCPP Single-Column Model (SCM). He wrote and documented the entire SCM from scratch, which required the scientific understanding of how an SCM works and the technical skill to code in both Fortran and Python. He then connected several… Read More

Lead Story: A long-term vision of Hierarchical System Development for UFS

Summer 2023 | Despite significant improvement of model development and computational resources, model forecast issues still exist in numerical weather prediction (NWP) and Earth system models (ESMs), including the Unified Forecast System (UFS). Hierarchical System Development (HSD) (Ek et al. 2019 Read More

Director's Corner: Israel Jirak

Summer 2023 | DTC plays an important role in model development and evaluation for NOAA and the broader Unified Forecast System (UFS) community.  My first interaction with DTC was back in 2010 in the Hazardous Weather Testbed (HWT), when the Method for Object-Based Diagnostic Evaluation (MODE) was being tested for convective applications.  MODE is part of DTC’s Model Evaluation Tools (MET) and serves as an innovative alternative to traditional grid-based metrics for model evaluation.  MODE offers a… Read More

Summer 2023 | Weiwei Li joined the Research Applications Laboratory at NCAR in 2018. She leads and contributes to multiple projects focused on assessing model physics performance to inform their improvements in a modeling/forecasting system. She is currently working on testing and evaluation of the physical parameterizations, involving two major modeling systems, i.e., the Unified Forecast System (UFS) and the Model for Prediction Across Scales (MPAS). Her team uses partially idealized simulations… Read More

Visitors: Developing a METplus use case for the Grid-Diag tool

Visitor: Marion Mittermaier

Summer 2023 | Marion Mittermaier’s visitor project focused on developing a METplus use case for the Grid-Diag tool, which creates histograms for an arbitrary collection of data fields and levels. Marion used the Grid-Diag tool to investigate the relationship between the forecasted and observed precipitation accumulations for GloSea5, the UK Met Office ensemble seasonal prediction system and how the relationship evolved over time. The project is a sub-task of a larger body of work that uses… Read More
