v1.1.0

  • Support selecting alternative lat/lon/elev triplet as primary lat/lon/elev fields for ILVIS2 data. By default, the low_mode coordinates are used, which represent the center of the lowest detected mode within the waveform. This replicates the behavior of the valkyrie service this code is based on. Users may now choose between the following coordinate sets: low_mode (the default), high_mode, centroid (ILVIS2 v1 only), and highest_signal (ILVIS2 v2 only).
  • Update documentation around ILVIS2 datasets and their multiple tuplets of lat/lon/elev fields.
  • Update data model for IceflowDataFrame to include dataset, which gives the dataset short name and version as a string (e.g., ILVIS v2 is "ILVISv2").
  • Add total_size_mb property to IceflowSearchResult and log size when downloading.

v1.0.0

  • Update transform_itrf function to be more flexible. Both forward and reverse transformations between proj-supported ITRFs are now supported, which means that more ITRF-to-ITRF transformations are handled.
  • Update icepyx dependency to >=2.0.0 for the "Using nsidc-iceflow with icepyx to Generate an Elevation Timeseries" notebook.
  • Filter for cloud-hosted data, avoiding duplicate granule results from fetch.find_iceflow_data
  • Pass through search kwargs to earthaccess without any type validation. This allows earthaccess to do watever validation it needs to, and then it passes those on to CMR. This provides much greater flexibility over data search and makes the interface more consistent with icepyx and earthaccess. #51.
  • Remove restrictive fetch_iceflow_df function from public API. Users should utilize the search, download, and read functions described in doc/getting-started.md instead.

v0.3.0

  • Use pydantic to create custom BoundingBox class for DatasetSearchParameters.
  • transform_itrf will calculate plate for source ITRF if not given with target_epoch.
  • Add support for ILATM1B v2 and BLATM1B v1.
  • Add support for ILVIS2 v1 and v2.
  • Improve API, providing ability to search across datasets and save to intermediate parquet file.
  • Add jupyter notebook showing use of nsidc-iceflow alongside icepyx

v0.2.0

  • Use pydantic to manage and validate dataset & dataset search parameters.
  • Fixup use of pandera to actually run validators.
  • Use np.nan for nodata values instead of 0.
  • Update package structure to be namespaced to nsidc and publish to PyPi.

v0.1.0

  • Initial release
