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, with computations performed on NCAR’s HPC resources (Casper / Derecho).

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

🌐 Multiple Access Methods¶

Some notebooks use intake / intake-ESM catalogs that support more than one access pattern:

• POSIX — direct filesystem access for NCAR HPC users

• HTTPS — web-based access for remote users
