August 2025 Updates


NGIAB Journal Paper
🎉We are excited to announce that our NGIAB paper 'NextGen In A Box (NGIAB): Open-Source Containerization of the NextGen Framework to Enable Community-Driven Hydrology Modeling' has been accepted for publication in Environmental Modelling and Software!
The paper is now available online and can be accessed here.
NGIAB-data-preprocess
A new release of ngiab_data_preprocess, version v4.5.0, is now available! Preprocessing support for the LSTM model has now been integrated, making LSTM-based NGIAB configurations far more accessible.
NGIAB-CloudInfra
NGIAB version 1.5.0 is available now. This update restricts searches for realization.json to the config folder. Additionally, the LSTM model has been integrated into the NGIAB image, enabling AI-powered hydrologic prediction.
NGIAB-HPCInfra
NGIAB-HPCInfra version 1.1.0 is available now. This update brings parity with NGIAB-CloudInfra's recent changes, including full support for LSTM-based models.
ngen-datastream
ngen-datastream is now known as the NextGen Research DataStream (NRDS)! We hope to continue using this platform to advance the boundaries of continental-scale modeling.
Release v1.1.0 recently released! Major enhancements include implementation of medium range ensemble members in DataStreamCLI and NRDS infrastructure, enhanced metadata and CI/CD with semantic versioning implementation, development towards automated testing and production deployment, the DataStreamCLI skip feature, increased test coverage, and documentation updates.
CIROH-UA/ngen
Upstream updates to BMI submodules have been merged! The CFE module has fixes to volume start and pointer handling, and the LSTM module has been updated to fully incorporate the CIROH community fork.
CIROH-UA/t-route
Version v0.2.0 of CIROH-UA/t-route is available now. This marks the formal release of last month's memory and performance improvements.
