Earth2Studio general release 0.16.0

🚨 Breaking Changes 🚨

  • No notable breaks this release 🎉

📕 Changelog

🌎 Added

  • Added AIFS 2.0 prognostic model (AIFS2) with wave and 10 hPa pressure level support
  • Added AIFS 2.0 ensemble prognostic model (AIFS2ENS) with stochastic noise injection
  • Added U-CAST prognostic model (UCast) with 1.5-degree global ERA5
    forecasting support
  • Added wave variables to IFS data source for AIFS2 support
  • Added NCEP CFSv2 operational forecast data sources for the pressure-level
    pgbf and surface-flux flxf products (CFS_FX, CFS_FX_Flux), backed by
    either NOMADS (real-time) or the AWS Open Data mirror (archive)
  • Added NCEP CFSv2 6-hourly 9-month reforecast data sources
    (CFS_Reforecast_FX, CFS_Reforecast_FX_Flux), covering 1981-12-12
    through 2011-03-27 with cycles every 5 days, served from the NCEI HTTPS
    archive
  • Added IBTrACS tropical cyclone track DataFrame source (IBTrACS)
  • Added checkpoint/session utilities and restart support for deterministic,
    diagnostic, and ensemble inference workflows
  • Added EUMETNET OPERA European weather radar composite DataSource for DBZH
    reflectivity, rain rate, and 1-hour accumulation (OPERA)
  • Added support for cumulative variables in ARCO data source
  • Added DLESyM-v0-ISCCP-ERA5 climate model

⚙️ Changed

  • UFS GSI observation sources (UFSObsConv, UFSObsSat) now fetch from S3 via native
    obstore instead of s3fs to avoid the Python-GIL bottleneck that caps fsspec's
  • Renamed AIFS runoff and snowfall variables to ro06 and sf06 and added six-hour
    accumulated IFS/AIFS data aliases.
  • Automatic test skipping for missing optional dependencies via
    pytest_ignore_collect hook in test/conftest.py

🔨 Fixed

  • Fixed ARCO data source ARCO_TIME_STOP fallback to 2025-12-31,
    reflecting the most recent available data in the bucket
  • Fixed ZarrBackend chunk metadata reload to skip coordinate arrays when reopening Zarr stores.

📦 Dependencies

  • Added obstore>=0.8 to core dependency list
  • Removed aifs and aifsens from the [all] extra due to dependency conflicts with
    aifs2 (incompatible anemoi-models versions).
