climate-ref-example

PyPI version Documentation Status License Python Version

This package provides an example implementation of a diagnostic provider for the Climate REF (Rapid Evaluation Framework). It serves as a template and reference for developers who want to create their own diagnostic providers.

Installation

pip install climate-ref-example

Features

  • Example implementation of a diagnostic provider
  • Global mean timeseries diagnostic demonstration
  • Complete implementation of all required interfaces
  • Test data specification for reproducible testing

Usage

Enable the provider in your ref.toml configuration:

[[diagnostic_providers]]
provider = "climate_ref_example:provider"

Then run diagnostics:

ref solve --provider example

Example Diagnostic

The package implements a GlobalMeanTimeseries diagnostic that calculates the annual mean global mean timeseries for CMIP6 datasets:

from climate_ref_core.providers import DiagnosticProvider
from climate_ref_core.diagnostics import Diagnostic, DataRequirement, ExecutionDefinition, ExecutionResult
from climate_ref_core.datasets import FacetFilter, SourceDatasetType

class GlobalMeanTimeseries(Diagnostic):
    """Calculate the annual mean global mean timeseries for a dataset."""

    name = "Global Mean Timeseries"
    slug = "global-mean-timeseries"

    data_requirements = (
        DataRequirement(
            source_type=SourceDatasetType.CMIP6,
            filters=(FacetFilter(facets={"variable_id": ("tas", "rsut")}),),
            group_by=("source_id", "variable_id", "experiment_id", "variant_label"),
        ),
    )
    facets = ("source_id", "variable_id", "experiment_id", "variant_label", "region", "metric", "statistic")

    def execute(self, definition: ExecutionDefinition) -> None:
        # Perform the diagnostic calculation
        ...

    def build_execution_result(self, definition: ExecutionDefinition) -> ExecutionResult:
        # Build and return the execution result
        ...

# Register diagnostics with a provider
provider = DiagnosticProvider("Example", __version__)
provider.register(GlobalMeanTimeseries())

Creating Your Own Provider

Use this package as a template:

cp -r packages/climate-ref-example packages/climate-ref-myprovider
