v1.0.5

2024-08-19

This version of HOSS updates the is_index_subset method to check for empty list (in case of dimensions subset) as well as None (for the spatial, bbox and temporal subsets). This prevents 1-D dimension variables from being unnecessarily requested from OPeNDAP for variable subsets which needs to be done only for spatial and temporal subsetting requests. This also prevents a whole granule request when 1-D dimension variables were not present in the granule.

v1.0.4

2024-04-05

This version of HOSS implements black code formatting across the repository. There should be no functional changes in the service.

v1.0.3

2024-03-29

This version of HOSS handles the error in the crs_wkt attribute in ATL19 where the north polar crs variable has a leading iquotation mark escaped by back slash in the crs_wkt attribute. This causes errors when the projection is being interpreted from the crs variable attributes.

v1.0.2

2024-02-26

This version of HOSS correctly handles edge-aligned geographic collections by adding the attribute cell_alignment with the value edge to hoss_config.json for edge-aligned collections (namely, ATL16), and by adding functions that create pseudo bounds for edge-aligned collections to make HOSS use the dimension_utilities.py function, get_dimension_indices_from_bounds. The pseudo bounds are only used internally and are not returned in the HOSS subset.

This change also includes an addition of a CF override that addresses an issue with the ATL16 metadata for the variables /spolar_asr_obs_grid and /spolar_lorate_blowing_snow_freq where their grid_mapping attribute points to north polar variables instead of south polar variables. This CF Override can be removed if/when the metadata is corrected.

v1.0.1

2023-12-19

This version of HOSS removes custom, redundant download retry logic. Instead retries are relied upon from harmony-service-lib and for each stage in a Harmony workflow.

v1.0.0

2023-10-06

This version of the Harmony OPeNDAP SubSetter (HOSS) contains all functionality previously released internally to EOSDIS as sds/variable-subsetter:0.3.6. Minor reformatting of the repository structure has occurred to comply with recommended best practices for a Harmony backend service repository, but the service itself is functionally unchanged. Additional contents to the repository include updated documentation and files outlined by the NASA open-source guidelines.

Repository structure changes include:

  • Migrating pymods directory to hoss.
  • Migrating subsetter.py to hoss/adapter.py.
  • Addition of hoss/main.py.
