intake-coops 0.4.0

Intake interface to NOAA CO-OPS data

intake-coops

Intake interface to NOAA CO-OPS data

Uses the noaa_coops package to read in NOAA CO-OPS data.

Currently limited to currents only with limited selections. Returns an xarray Dataset, but there are intake Sources for both DataFrame and xarray.

This is intake v1 still.

Project based on the cookiecutter science project template.

Installation

PyPI

>>> pip install intake-coops

Local installation

Clone from github (HTTPS or SSH)

>>> git clone https://github.com/axiom-data-science/intake-coops.git

Install environment file

>>> conda env create -f environment.yml

Activate new environment

Example Usage

If you input to intake.open_coops_cat() the keyword argument process_adcp=True, the ADCP Dataset will contain velocity on u and v components, along- and across-channel components, and along- and across-channel subtidal signal (processed with pl33 tidal filter, also included).

import intake_coops

stations = ["COI0302", "COI0512"]
cat = intake_coops.COOPSCatalogReader(stations).read()

# sources in catalog
print(list(cat))

# look at a source
print(cat["COI0302"])

# read in data to a Dataset
ds = cat["COI0302"].read()
