[jira] [Created] (CLIMATE-914) Update dataset_processor.spatial_regrid module

Huikyo Lee created CLIMATE-914:
----------------------------------

             Summary: Update dataset_processor.spatial_regrid module
                 Key: CLIMATE-914
                 URL: https://issues.apache.org/jira/browse/CLIMATE-914
             Project: Apache Open Climate Workbench
          Issue Type: Bug
          Components: regridding/data processing
    Affects Versions: 1.2.0
            Reporter: Huikyo Lee
            Assignee: Huikyo Lee
            Priority: Blocker
             Fix For: 1.3.0


OCW's spatial regridding has used scipy.ndimage.map_coordinates. For some unknown reasons, the map_coordinates function outputs -9999. as a missing value without a mask. We will replace map_coordinates with scipy.interpolate.griddata that is widely used in the climate science communities.
