Introduction

Welcome to NCAR GDEX Examples — a collection of Jupyter notebooks that demonstrate geoscientific workflows using data from NCAR’s Geoscience Data Exchange (GDEX). Each example shows how to access a specific GDEX dataset and use it for analysis or visualization.

How is the site organized?¶

Examples are grouped into sections by data type:

• Observations — satellite, in-situ measurements

• Analysis — NCEP GFS analyses

• Reanalysis — ERA5, JRA-3Q, etc.

• Simulations — model output (CESM, CMIP, etc.)

• Data Fusion — combinations of two or more datasets

• Background & Concepts — supporting material (e.g., the Zarr format)

• Contribution — guide for adding new examples

🌐 Runs on HPC, Binder, or your laptop¶

Every notebook auto-detects where it is running and picks the data path for you:

• POSIX — direct filesystem access where /gdex/data is mounted (NCAR HPC, CIRRUS BinderHub)

• OSDF — streamed over the Open Science Data Federation when off-cluster (laptops, other hubs)

No edits are needed to move between them.
