Autumn 2021 | During their recent project for the DTC Visitor Program, Michael Iacono and John Henderson of Atmospheric and Environmental Research (AER) used the Hurricane Weather Research and Forecasting model (HWRF) to investigate an improved way to represent the sub-grid variability and vertical overlap of partial cloudiness within the calculation of atmospheric radiative transfer. Their exponential-random (ER) cloud overlap advancement was adopted by NOAA in the 2020 operational HWRF. … Read More

Director's Corner: DTC Outlook for the Future
Louisa Nance
Summer 2021 | Over the years, a major component of the DTC’s approach to facilitating the transition of research innovations into operations has been its support for distributed development of community software that includes the capabilities of the current operational systems. This software support has provided the foundation for conducting testing and evaluation that can inform the research to operations (R2O) process. The DTC’s software support responsibilities have involved, to varying degrees… Read More
Lead Story: Accelerating Progress of the Unified Forecast System through Community Infrastructure
Summer 2021 | The goals of the Unified Forecast System (UFS) are ambitious: construct a unified modeling system capable of replacing dozens of independently developed and maintained operational prediction systems, while simultaneously paving the way for researchers in NOAA labs and the broader NWP community to access and use that system, improve it, and contribute their own innovations. Toward these goals, the UFS… Read More
Who's Who: Mrinal Biswas
Summer 2021 | Mrinal Biswas was born and raised in Durgapur, West Bengal, India, a small industrial town. He was raised by a Civil Engineer father while his mother took care of him and his sister. He enjoyed school but even more enjoyable was the time he played outdoors with his friends late into the evening. He was fascinated with anything electronic from radios to vinyl record players, even watches, disassembling them while his mom took his sister to school and quickly re-assembling them before… Read More
Bridges to Operations: METplus for Operational Verification and Diagnostics
Summer 2021 | The idea of including the enhanced Model Evaluation Tools (METplus) in NOAA operations for the verification and validation of Environmental Modeling Center (EMC)’s suite of environmental prediction models has been a decade in the making. METplus is the DTC-developed verification framework that spans a wide range of… Read More
Visitors: Evaluating CCPP Physics Across Scales for Severe Convective Events
Visitor: William Gallus, Jr
Summer 2021 | The DTC Visitor Program offers a unique means of gaining experience with state-of-the-art modeling and visualization approaches. During my visits with the DTC through this program the previous three times, I explored these diverse areas of study, and was able to provide several graduate students with unique opportunities in these areas: the DTC's first convection-allowing model (CAM)… Read More
