v1.3.5 April 2026 Release

Scope of Work

• Updates the API endpoint for sea ice concentration to allow for communities and point locations close to the shoreline by removing fixed coastal mask that omitted certain communities (PR #714)

v1.3.4 March 2026 Release

Scope of Work

• The TAS 2km endpoint /tas2km/point/ has been updated to use WCS-optimized coverages for both the historical and projected data. This has improved response times, reducing the time it takes to get a point of data back from 3.9 minutes to 1.4 seconds. (PR #688)
• The CMIP6 monthly endpoint /cmip6/point/ has been updated to use a WCS-optimized coverage for returning the large amount of monthly CMIP6 data. This has improved response times, reducing the time it takes to get a point of data back from 5+ minutes to 8 seconds. (PR #689)
• The zonal statistics for area summaries was originally running interpolation on each unique dimension set. This changes that so this only runs the interpolation function once across all of the unique dimensions at the same time. (PR #698)

v1.3.3 November 2025 Release

Scope of Work

• The Beaufort Sea and Chukchi Sea SLIE (Landfast Sea-Ice Extent) endpoint have been updated to point to WCS-only coverages; this change yields a dramatic improvement in response times for those endpoints. (PR #630)
• Added new endpoints for dynamically downscaled ERA5 WRF reanalysis climate data: both points and areas are now supported (PR #615 and PR #643)
• Added a new endpoint for Fire Weather Indices, enabling users to access fire-weather-relevant metrics derived from ERA5 and CMIP6 model output; both points and areas are supported (PR #636 and PR #661)
• Added a new downscaled CMIP6 endpoint, allowing daily resolution access to downscaled CMIP6 models and scenarios for the state of Alaska. (PR #653)
• Established a minimal test suite covering a few representative area queries, along with GitHub automation to run these tests on every PR into main. (PR #651 and PR #656)
• Adds spruce beetle paper reference to beetles endpoint documentation. (PR #659)

v1.3.2

Searching for place names at the /places/search/communities endpoint is now “fuzzy”, returning near-matches to improve returned results.

v1.3.1

• A new route has been added to the SNAP Data API, currently used exclusively by the ARDAC application: /places/search/communities
  • This endpoint accepts two optional GET parameters: extent and substring. It was developed to support dynamic filtering for the community search boxes within ARDAC's X-ray items. Previously, the filtering logic was handled entirely within the ARDAC front-end, which required loading the entire set of communities and subsetting them on-the-fly. Now, that filtering is offloaded to the API, significantly improving performance and simplifying the ARDAC interface logic.

v1.3.0

Updates made to earthmaps.io

• A new “Temperature Anomalies” endpoint has been added that provides a 1951-1980 mean baseline temperature and differences from that baseline for historical Berkeley Earth data and projected CMIP6 data
• The code to generate ArcticEDS reports has been refactored to be simpler to follow and no longer use multiple asynchronous network calls to the API
• Performance improvements for point queries that are outside of an endpoint’s data extent
• High/low confidence intervals are now provided for all health-related demographics data, with a consistent 90% confidence level for each
• Improvements to CMIP6 and places & boundaries documentation

v0.2

Updates made to earthmaps.io

• Adds Demographics & Health endpoint
• Adds CMIP6 monthly data endpoint that returns any combination of these variables:
  • Near-surface Air Temperature
  • Maximum Near-surface Air Temperature
  • Minimum Near-surface Air Temperature
  • Near-surface Wind Speed
  • Near-surface Eastward Wind Speed
  • Near-surface Northward Wind Speed
  • Sea Level Pressure
  • Surface Temperature
  • Precipitation
  • Evaporation
  • Downwelling Shortwave Flux
  • Downwelling Longwave Flux
  • Upward Sensible Heat Flux
  • Upward Latent Heat Flux
  • Cloud Area Fraction
• Replaces CMIP6 indicators endpoint data with indicators derived from latest iteration of regridded CMIP6 data
• Updated Landfast Sea Ice endpoint for latest version of data that includes all sources (satellite and ice chart) for both the Chukchi and Beaufort Sea Regions, 1996-2023
