Community Updates

The Alabama Water Institute published a news article highlighting how CIROH's community resources continue to advance open, collaborative water modeling.

Introducing the Community NextGen Ecosystem! NGIAB, NRDS, and CCNH have been unified under the Community NextGen Ecosystem documentation section. CIROH Hub will continue to surface the latest documentation for NGIAB and related tools, such as newly-added documentation for rs_route.

Community FIM Ecosystem documentation has been newly added to the CIROH Hub. It offers a flood modeling-to-evaluation framework for flood inundation modeling, simulation, benchmarking, and evaluation.

Additonally, a new research testbed replicating the look of water.noaa.gov is now live at nwps.ciroh.org, providing a sandbox for experimenting with the National Water Prediction Service (NWPS) interface.

CIROH is expanding the Pantarhei cluster. For migration of data or to get access to new Pantarhei 2.0 system, please submit an IT ticket using the linked issue template.

The Pantarhei and Wukong clusters are slated for a temporary full outage targeted for mid-October to migrate hardware to a new UA HPC datacenter and execute critical software updates. Final dates will be announced once confirmed, but users should begin planning job submissions now and prepare to save all work and terminate active processes prior to the shutdown.

The Confluence Webinar Series is underway! Learn more via the new CIROH Hub Calendar.

Ten graduate students across three teams (Don't Runoff!, FlashCast, and The Post-Processors) spent seven weeks at the 2026 Water Prediction Innovators Summer Institute advancing quantitative precipitation inputs into the NextGen Framework, using NextGen In A Box (NGIAB) and NSF ACCESS Jetstream2 allocations provided through CIROH cyberinfrastructure. Read more in the blog post.

The University of Alabama's Surface Dynamics Modeling Lab (SDML), with CIROH support, has built the CIROH FIM Community Ecosystem: an interconnected, open-source, cloud-native suite of Python tools spanning flood inundation modeling, simulation, benchmarking, and evaluation at national scale. Read more in the blog post.

This summer's Research Experience for Undergraduates (REU) program put NSF ACCESS Jetstream2 cyberinfrastructure to work, giving students hands-on experience. Read more in AWI News.

The Community Hydrofabric Viewer is now live, providing an interactive way to explore the CIROH Community Hydrofabric.

The awiciroh/ciroh-ngen-image Docker image has surpassed 50,000 pulls! Learn more at ngiab.ciroh.org.

This release adds support for the new owp-master image, which allows for easy head-to-head testing between the master and CIROH-UA branches of ngen. Other changes include enhancements to the model and build documentation, improving the model integration form, upgrading dHBV2.0 packages with corrected weights/config paths, and moving CASAM's van Genuchten parameters into shared static datasets. Pinned to CIROH-UA/ngen commit 61c1400 and CIROH-UA/t-route commit f39b8d4.

This month's release fixes the elevation unit conversion in the Snow-17 module (#252). A new subset CLI has also been merged, adding a standalone entry point that subsets a user-provided geopackage by user-defined catchment ID.

This release resolves a backwards-compatibility issue to ensure DataStreamCLI works with any datastream or integrated container, and adds a new Getting Started guide walking users through its options.

This release adds a new NRDS datastream for USGS streamflow kriging (qkrig). The qkrig datastream produces NextGen-compatible kriged streamflow fields from USGS observations, expanding the set of operationally available observation products. Other key changes include a comprehensive datastream catalog document and several reliability improvements.

This release adds enhanced metadata with per-variable forcing statistics, support for explicitly supplying a weights file in the configuration, and publishes the Docker container to GitHub Container Registry, alongside black formatting and bug fixes.

The NRDS Visualizer has been reworked with event-driven DataStream loading, archived flowpath geometry with tiles below zoom 7, a single-file OPFS cache, retry paths, accessible names, AA-contrast tokens, a unified spinner, and 232 new tests.
