Abstract
This HydroShare resource contains Jupyter Notebooks with instructions and code for accessing and subsetting the NOAA Analysis of Record for Calibration (AORC) dataset. The resource includes four Jupyter Notebooks:
1. AORC_LL_PointRetrieval.ipynb: Retrieves and aggregates data from the latitude-longitude gridded dataset for a specific point specified using geographic coordinates.
2. AORC_LL_ZoneRetrieval.ipynb: Retrieves and aggregates data from the latitude-longitude gridded dataset for an area defined by a polygon shapefile.
3. AORC_NWMProj_PointRetrieval.ipynb: Retrieves and aggregates data from the NWM projected dataset for a specific point specified using geographic coordinates.
4. AORC_NWMProj_ZoneRetrieval.ipynb: Retrieves and aggregates data from the NWM projected dataset for an area defined by a polygon shapefile.
These notebooks programmatically retrieve the data from Amazon Web Services, aggregate it at user-defined time scales (which may differ from NOAA’s original time steps), and, in the case of shapefile-based data retrieval, compute the average over the shapes in the given shapefile.
The provided notebooks are coded to retrieve data from AORC version 1.1 in Zarr format, either from the latitude-longitude gridded dataset (https://registry.opendata.aws/noaa-nws-aorc/) or the NWM projected dataset (https://registry.opendata.aws/nwm-archive/)

Jupyter Notebooks for the Retrieval of AORC Data for Hydrologic Analysis
This resource includes the following files:
- AORC_LL_PointRetrieval.ipynb: Retrieves and aggregates data from the AORC latitude-longitude gridded dataset for a specific point specified using geographic coordinates.
- AORC_LL_ZoneRetrieval.ipynb: Retrieves and aggregates data from the AORC latitude-longitude gridded dataset for an area defined by a polygon shapefile.
- AORC_NWMProj_PointRetrieval.ipynb: Retrieves and aggregates data from the NWM projected dataset for a specific point specified using geographic coordinates.
- AORC_NWMProj_ZoneRetrieval.ipynb: Retrieves and aggregates data from the NWM projected dataset for an area defined by a polygon shapefile.
- aorc_utils.py: A Python script containing functions used by the notebooks.
- requirements.txt: Lists the specific python library dependency versions required to run the notebooks.
- GSLSubbasins: A shapefile of the Great Salt Lake Basin used as an example.
- AORC_DataRetrieval.pdf: Notes on the coordinate systems and some of the differences between the datasets.
- README.md: Explains the content of this resource.
To use this resource in HydroShare, select Open With on one of the available application servers to launch the corresponding JupyterHub environment. Then, open the Jupyter Notebook for the format of the data you wish to retrieve and follow the instructions.
This resource is designed to be opened from a JupyterHub platform connected to CUAHSI HydroShare. It has been tested using CUAHSI JupyterHub, CIROH JupyterHub, and CyberGIS-Jupyter for Water. Note: In CyberGIS-Jupyter for Water, use the Python 3-2024-03 kernel to avoid package conflicts.
The development versions of these notebooks are available on GitHub: https://github.com/CUAHSI/notebooks in the Data Access Examples / AORC - Retrieval of AORC Data for Hydrologic Analysis folder.
