Data Organization

Every dataset page includes:

  • Overview (summary, citation, documentation)
  • Products / groups (how files are organized)
  • Variables / parameters
  • Data Access options (subset, GLADE, web, Globus)

Each dataset contains:

  • Products / Groups -broad categories (e.g., fields, resolutions)
  • Variables / Parameters -scientific variables you can select
  • Files over time - e.g., daily, monthly, or hourly files
  • Metadata & documentation - what the data means and how to use it

How do you want to access data?

Get a subset (recommended for many users) – Download only the variables and region you need.

Web / HTTP download – For simple file downloads through your browser.

Access via GLADE (NCAR/UCAR only) – For internal users working on Derecho/Casper.

Globus – For large/bulk transfers.

THREDDS – For programatic data access.

  • Global Search - Best for known dataset names or keywords. Example: “ERA5”, “temperature”, “ds633.0”
  • Browse by Category - Best for exploring without a dataset in mind. Example: “Surface” or “Reanalysis”

Search within a Dataset Page - Find parameters, variables, or groups once you’ve found a dataset. Supports subsetting, filtering, and reviewing metadata.
