class tsdat.pipeline.pipelines.IngestPipeline

Bases: tsdat.pipeline.base.Pipeline

Pipeline class designed to read in raw, unstandardized time series data and enhance its quality and usability by converting it into a standard format, embedding metadata, applying quality checks and controls, generating reference plots, and saving the data in an accessible format so it can be used later in scientific analyses or in higher-level tsdat Pipelines.

Class Methods

hook_customize_dataset	Code hook to customize the retrieved dataset prior to qc being applied.
hook_finalize_dataset	Code hook to finalize the dataset after qc is applied but before it is saved.
hook_plot_dataset	Code hook to create plots for the data which runs after the dataset has been saved.
run	Runs the data pipeline on the provided inputs.

Method Descriptions

hook_customize_dataset(self, dataset: xarray.Dataset) → xarray.Dataset

Code hook to customize the retrieved dataset prior to qc being applied.

Parameters

dataset (xr.Dataset) – The output dataset structure returned by the retriever API.

Returns

xr.Dataset – The customized dataset.

hook_finalize_dataset(self, dataset: xarray.Dataset) → xarray.Dataset

Code hook to finalize the dataset after qc is applied but before it is saved.

Parameters

dataset (xr.Dataset) – The output dataset returned by the retriever API and modified by the hook_customize_dataset user code hook.

Returns

xr.Dataset – The finalized dataset, ready to be saved.

hook_plot_dataset(self, dataset: xarray.Dataset)

Code hook to create plots for the data which runs after the dataset has been saved.

Parameters

dataset (xr.Dataset) – The dataset to plot.

run(self, inputs: List[str], **kwargs: Any) → xarray.Dataset

Runs the data pipeline on the provided inputs.

Parameters

• inputs (List[str]) – A list of input keys that the pipeline’s Retriever class

• pipeline. (can use to load data into the) –

Returns

xr.Dataset – The processed dataset.

class tsdat.pipeline.pipelines.TransformationPipeline

Bases: IngestPipeline

Pipeline class designed to read in standardized time series data and enhance its quality and usability by combining multiple sources of data, using higher-level processing techniques, etc.

retriever :tsdat.io.retrievers.StorageRetriever

Class Methods

run	Runs the data pipeline on the provided inputs.

Method Descriptions

run(self, inputs: List[str], **kwargs: Any) → xarray.Dataset

Runs the data pipeline on the provided inputs.

Note that input keys to TransformationPipelines are different than inputs to IngestPipelines. Here each input key is expected to follow a standard format:

“datastream::start-date::end-date”,

e.g., “sgp.myingest.b1::20220913.000000::20220914.000000”

This format allows the retriever to pull datastream data from the Storage API for the desired dates for each desired input source.

Parameters

• inputs (List[str]) – A list of input keys that the pipeline’s Retriever class

• pipeline. (can use to load data into the) –

Returns

xr.Dataset – The processed dataset.
