cdo-flow
Workflow orchestration layer for CDO-based climate analysis, built on top of python-cdo-wrapper.
Install
pip install cdo-flow
Requires CDO to be installed for steps that execute CDO operators.
Quick start
from cdo_flow import Workflow, python_step, cdo_step
from python_cdo_wrapper.query import CDOQueryTemplate
# Pure Python step
@python_step
def write_data(ctx):
ctx.output("result.txt").write_text("hello")
# CDO step via decorator
@cdo_step
def regrid(ctx, cdo):
cdo.query(ctx.inputs["data"]).remap_bil("r360x180").to_file(ctx.output("regridded.nc"))
# Inline CDO chain
wf = Workflow(name="demo", run_dir="./runs")
wf.add_step("write", write_data)
wf.add_step(
"select_tas",
chain=CDOQueryTemplate().select_var("tas").year_mean(),
inputs={"data": "/path/to/input.nc"},
output=["tas_annual.nc"],
)
result = wf.run()
YAML workflows
