  • New function create_time_bounds in clisops.utils.time_utils, to generate time bounds for temporally averaged datasets.

  • clisops now uses the loguru library as its primary logging engine (#216). The mechanism for enabling log reporting in scripts/notebooks using loguru is as follows:

import sys
from loguru import logger

LEVEL = "INFO || DEBUG || WARNING || etc."
logger.add(sys.stdout, level=LEVEL)  # for logging to stdout
# or
logger.add("my_log_file.log", level=LEVEL, enqueue=True)  # for logging to a file

v0.8.0 (2022-01-13)

New Features

  • clisops.core.average.average_shape copies the global and variable attributes from the input data to the results.

  • Fix added to remove _FillValue added to coordinate variables and bounds by xarray when outputting to netCDF.

Other Changes

  • Passing DataArray objects to clisops.core.average.average_shape is now deprecated. Averaging requires grid cell boundaries, which are not DataArray coordinates, but independent Dataset variables. Please pass Dataset objects and an optional list of variables to average.

  • average_shape performs an initial subset over the averaging region, before computing the weights, to reduce memory usage.

  • Minimum xesmf version set to 0.6.2.

  • Minimum pygeos version set to 0.9.

  • Replace cascaded_union by unary_union to anticipate a shapely deprecation.

  • Notebook of examples for subset operation added.

  • split_method implemented to split output files by if they exceed the memory limit provided in clisops.etc.roocs.ini named file_size_limit. Currently only the time:auto exists which splits evenly on time ranges.
