Accelerating Innovation: CIROH's March 2024 Update

The CIROH team has been diligently accelerating research cyberinfrastructure capabilities this month. We're thrilled to share key milestones achieved in enhancing the Community NextGen project and our cloud/on-premises platforms.

A significant highlight was the successful launch of our new fully operational on-premises infrastructure. Comprehensive documentation is now available here, ensuring seamless access and utilization. Additionally, we've fortified the NextGen in a Box (NGIAB) ecosystem with bug fixes, repository enhancements, and initiated work on automating the CI pipeline for the Singularity Repo

Empowering our community remains a top priority. We've expanded the DocuHub knowledge base with dedicated sections on on-premises access guidelines, as well as policies and best practices for optimized infrastructure usage here . Furthermore, our team represented CIROH at the AWRA Geospatial Water Technology Conference in Orlando, sharing insights on leveraging geospatial data for water research. Refer here

As we continue driving advancements, we extend our gratitude for your unwavering support of the Community NextGen project and CIROH's cyberinfrastructure endeavors. Be on the lookout for more exciting updates next month as we strive to unlock new frontiers in water science through robust computing capabilities.

Monthly News Update - February 2024

One min read

Welcome to the February edition of the CIROH DocuHub blog, where we bring you the latest updates and news about the Community NextGen project and CIROH's Cloud and on-premise Infrastructure.

Our team has been hard at work enhancing CIROH's Infrastructure and Community NextGen tools. Here are some highlights from February 2024:

  1. We successfully launched our new On-premises Infrastructure, which is now fully operational. You can find documentation for it here.

  2. For NGIAB, we've made improvements to the CI pipeline for pull requests submitted with forked repositories. Now, we automatically build and test these submissions using the CI pipeline.

  3. We've added documentation for the NWMURL python package, which offers utility functions tailored for accessing National Water Model (NWM) data URLs. This library streamlines the process of accessing NWM data for various purposes, including analysis, modeling, and visualization. You can explore the documentation here.

  4. We're thrilled to announce the NextGen Track for DevCon24. The schedule is now available at: DevCon24 Schedule.

Thank you for your ongoing interest and support in the Community NextGen project. Stay tuned for more exciting updates and developments next month. 馃槉

NextGen Monthly News Update - January 2024

2 min read

Welcome to the January edition of the CIROH DocuHub blog, where we share the latest updates and news about the Community NextGen project monthly. NextGen is a cutting-edge hydrologic modeling framework that aims to advance the science and practice of hydrology and water resources management. In this month's blog, we will highlight some of the recent achievements and developments of the Community NextGen team.

First, we are excited to announce that NextGen In A Box (NGIAB) is now available with Singularity support. This means that you can run NGIAB on any HPC system that does not support Docker, using Singularity containers. Singularity is a popular tool for creating and running portable and reproducible computational environments. To learn how to use NGIAB with Singularity, please visit our GitHub repository: Ngen-Singularity.

Second, we have made several improvements and enhancements to NGIAB, such as updating the sample input data, upgrading the Boost library, adding auto mode run, and supporting geopackage format. You can find more details about these updates on our GitHub repository: NGIAB-CloudInfra.

Third, we would like to share with you is the development of NextGen Datastream, a tool that automates the process of collecting and formatting input data for NextGen, orchestrating the NextGen run through NextGen In a Box (NGIAB), and handling outputs. The NextGen Datastream is a shell script that orchestrates each step in the process, using a configuration file that specifies the data sources, parameters, and options for the NextGen run. The NextGen Datastream can also generate its own internal configs and modify the configuration file as needed. You can find more details and instructions on how to use the NextGen Datastream on our GitHub repository: ngen-datastream.

We hope you enjoyed this blog and found it informative and useful. If you have any questions, comments, or feedback, please feel free to contact us at Thank you for your interest and support in the Community NextGen project. Stay tuned for more exciting news and developments in the next month. 馃槉

NextGen Framework Forcings

A new forcing processor tool has been made public. This tool converts any National Water Model based forcing files into ngen forcing files. This process can be an intensive operation in compute, memory, and IO, so this tool facilitates generating ngen input and ultimately makes running ngen more accessible.
