dodola

Containerized application for running the steps in a larger, orchestrated CMIP6 bias-correction and downscaling workflow.

This is under heavy development.

Features

Commands can be run through the command line with dodola <command>.

    validate-dataset              Validate a CMIP6, bias corrected or...

See dodola --help or dodola <command> --help for more information.

Example

From the command line, you replicate one of the downscaling workflow's validation steps with:

dodola validate-dataset <InsertZarrStoreURLhere> \
  --variable "tasmax" \
  --data-type "downscaled" \
  -t historical

Alternatively, the service used by this command can be called directly from Python in dodola.services.

Installation

dodola is generally run from within a container. But, you can install the application and access the command-line interface or Python API with pip:

pip install git+https://github.com/ClimateImpactLab/dodola

the dependencies used in the container are in ./environment.yaml.
