v2.0.0

What's new in 2.0.0 (16 May 2025)

These are the changes in icepyx 2.0.0. See https://icepyx.readthedocs.io/en/latest/user_guide/changelog/index.html for a full changelog including other versions of icepyx.

Warning

This is major release and contains a few breaking changes. Full details will be described in the documentation.

NSIDC (the NASA DAAC that hosts ICESat-2 data) is transitioning their API endpoint from the on-premises EGI system to the cloud-based Harmony services. icepyx has been updated to access these new services; Certain capabilities are temporarily going away

• Data reformatting: Currently no format transcoding is available for any ICESat-2 products, so users will only get HDF5 files back from the new Harmony API.
• Variable subsetting: The new cloud subsetter doesn't support variable subsetting (yet), therefore all variables will be included in subsetted orders.

Find more details on all these changes, including their progress, on GitHub issues and discussions.

New Features

• Adding support for NASA's Harmony subsetter (#657)

  • Data orders can be previewed, stopped and resumed using the library or the Harmony UI.
  • The Harmony trajectory subsetter automatically pauses orders with more than 300 granules, we need to manually resume them or pass the skip_preview=True parameter to the order.
  • Reference: https://harmony.earthdata.nasa.gov/

• Order class: when an order is placed, icepyx will return an order class instance that will help us keep track of the order progress, pause and eventually download the data.
  We can still use the Query class to download, however using the order instance is probably simpler and more intuitive. (#657)

Bug fixes

• None

Deprecations

• EGI API is deprecated (Closes #530)
  • PR #657 implements NASA Harmony support to replace the on-premises EGI service.
  • data reformatting and variable subsetting are not supported in the new API.
    • Users will only get HDF5 files back from the new API.
  • order_vars() is deprecated in favor of variables().
  • fmt_for_EGI() is deprecated.
  • Any EGI specific code is deprecated and has been removed in this release.
• Drop support for Python 3.9 and 3.10 (#655)
• Removed existing deprecations for v1.x (#640)

Maintenance

• Separate CI unit tests and integration tests with their own conftest (#657)
• Fixed some integration tests that were failing due to the new Harmony API #(657)
• Updated ruff action (#654)

Documentation

• Updated notebooks to reflect the new Harmony API usage (#657)
  • The updated notebooks include instructions for making full and subset orders, and show how to use the new Harmony API.
  • The top level API works the same, users only need to update to v2.0.0 and the code should work (unless using variable subsetting or reformatting)
  • Notebooks are in the doc/source/example_notebooks folder, and are also available on the Readthedocs documentation page.
• Include quest tile in index.rst (#497)

Other

• None
