Software Release: Announcing UPP V4.0.1 Bug Fix Release

2019-08-21 | Dear UPP Community, The Developmental Testbed Center (DTC) is pleased to announce the release of the Unified Post Processor Bug Fix Version 4.0.1. Significant bug fixes include: FV3GFS processing fix: Modified input format for processing FV3GFS data. Users should use UPPV4.0.1 for all FV3GFS processing. Previous versions are now considered legacy for FV3GFS. Users should use 'binarynemsiompiio' instead of 'binarynemsio' in their run script. The binarynemsio format option will not be supported in the future. Scripts in… Read More

Lead Story: The Community Leveraged Unified Ensemble in the NOAA/Hazardous Weather Testbed Spring Forecasting Experiments

Winter 2019 | The Community Leveraged Unified Ensemble, or CLUE, is an unprecedented collaboration between academic and government research institutions to help guide NOAA’s operational environmental modeling at the convection-allowing scale. The CLUE is produced during the annual NOAA Hazardous Weather Testbed (HWT) Spring Forecasting Experiment (SFE), where the primary goal is to document performance characteristics of experimental Convection-Allowing Modeling systems (CAMs). The HWT SFE is co-organized by NOAA’s National… Read More

Who's Who: Tracy Hertneky

Winter 2019 | Tracy Hertneky "floats through the air with the greatest of ease" -- or does she? This daring young woman flying in an aerial silk (one of her many hobbies is being an aerialist - like in the Cirque du Soleil)-- doesn’t actually like to fly and requests the superpower to be able to teleport. She dreams of visiting places from New Zealand to Belgium (loves the beer) and the Summer Olympics! Plus, the ability to teleport would certainly be more efficient for travel and help in her role as a new mom to Juliet who was… Read More

Bridges to Operations: Use of Model Evaluation Tools in NWS QPF Verification

Winter 2019 | The National Weather Service (NWS) Meteorological Development Laboratory (MDL) is developing an automated, nationally consistent and centralized service that verifies Quantitative Precipitation Forecasts (QPF). This QPF Verification Service (QPFVS)  will provide objective assessments of the predictive skill of numerical model guidance and official NWS forecasts to help increase the accuracy of quantitative precipitation forecasts. QPFVS will be implemented as a component of a larger gridded verification system with… Read More

Visitors: Towards a better understanding of the vertical aerosol distribution in the atmosphere

Winter 2019 | On 14 April 2010, increasing volcanic activity, including explosive eruptions, were observed at the Icelandic volcano Eyjafjallajökull. The volcano was largely unknown by the general public until then. On that particular day, however, the volcano started ejecting fine ash into the atmosphere, which was advected towards continental Europe. Major disruptions of the air traffic across western and northern Europe were necessary in order to ensure aviation safety. Several countries closed their airspace, affecting… Read More

Did you know?: The Formal FV3GFS Evaluation

Winter 2019 | Implementing the GFS global model with the FV3 dynamic core upgrade into the National Centers for Environmental Prediction (NCEP) Production Suite will be the first step towards a Unified Forecast System (UFS). But prior to any new code being delivered to NCEP Central Operations, the NCEP Director must decide whether the implementation should occur, based on recommendations from the Environmental Modeling Center (EMC) and customers and stakeholders in the field at the conclusion of a formal evaluation period. EMC’s… Read More
