Announcement: DTC - EPIC Hierarchical System Development Survey Now - Deadline Extended

2023-04-11 | All, Developmental Testbed Center (DTC) is working with the Earth Prediction Innovation Center (EPIC) to establish community requirements for a Hierarchical System Development (HSD) . This effort is focused on accelerating the rate of  improving numerical prediction across scales using the Unified Forecast System (UFS).  The requirements will be captured in a white paper. We would like to invite you to provide your input via this survey.  The goal of the survey is to identify: What gaps you feel exist in the UFS HSD… Read More

Lead Story: Using the CCPP SCM as a Teaching Tool

Winter 2023 | The climate graduate programs at George Mason University offer an Earth System Modeling course. The course is divided into two subtopics, theory and practicum. The theoretical session offers lectures introducing students to the physical and dynamical components of an Earth system model, their interactions, and how these components are used to predict the behavior of weather and climate. When I became the instructor of the Earth System Modeling course, I added a module to the practicum session that provides students the… Read More

Director's Corner: Hui-Ya Chuang

Winter 2023 | I was excited when the DTC nominated me to serve on the DTC Science Advisory Board in 2020 and then felt very honored to be asked to become a co-chair in 2022. As one of the first group of EMC staff to be sent to work with DTC on bridging the gap between research and operations, I have watched DTC grow into an organization that accomplished its mission to bridge the gaps, by not only providing community support for several operational softwares, but also facilitating collaboration by developing Common Community Physics… Read More

Who's Who: Mike Kavulich

Winter 2023 | Mike Kavulich grew up in suburban Connecticut, the oldest of three children with a younger brother and sister. From his earliest memories he had an obsession with the weather, giving weather reports to his class in preschool, watching and re-watching weather documentaries recorded from TV on VHS, and tracking hurricanes on a copied paper hurricane tracking map taped to the wooden basement door. Because he did not have cable or internet, he would call his grandmother every day of the late summer to turn on the Weather… Read More

Bridges to Operations: Informing NCEP Legacy Operational Model Retirement Through Scorecards

Winter 2023 | NOAA is undergoing a massive, community-driven initiative to unify the NCEP operational model suite under the Unified Forecast System (UFS) umbrella. A key component of this effort is transitioning from the legacy systems to unified Finite-Volume Cubed-Sphere (FV3)-based deterministic and ensemble operational global and regional systems. For the UFS, the goal is to consolidate operational models around a common software framework, reduce the complexity of the NCEP operational suite, and maximize available HPC resources,… Read More

Visitors: How do TC-specific Planetary Boundary Layer (PBL) physics impact forecasts across scales and UFS applications?

Visitor: Andrew Hazelton

Winter 2023 | One of the most important aspects of numerical modeling is the series of approximations made to represent certain physical processes, known as “parameterizations.” These approximations of critical atmospheric phenomena can make a huge impact on the solutions that a model provides, so making these parameterizations more accurate across a variety of applications is a major goal of numerical weather prediction (NWP).

Community Connections: JEDI projects adopts and contributes to CCPP variable naming standard

Winter 2023 | In September of 2022, the JCSDA (Joint Center for Satellite Data Assimilation) officially adopted the CCPP standard names, originally developed for use with the Common Community Physics Package, as the model variable names to be used within the JEDI (Joint Effort for Data assimilation Integration) software. The JEDI software is employed by many Earth observing systems and requires agreed-upon names to be used for the quantities being input and computed. It is critical that these names are understood identically between… Read More
