LaTiS Python Client

A client library for making LaTiS requests in Python.

Installation

We do not yet publish to PyPI so you need to install from Git:

python3 -m pip install git+https://github.com/lasp/latis-python-client.git

Usage

Use the read_data function to make a request to LaTiS and get the results as a Pandas DataFrame.

The read_data function expects the following arguments:

• base_url: The base URL of a LaTiS instance. The base URL includes the host and the path through /dap (for LaTiS 2) or /dap2 (for LaTiS 3).
• dataset: The identifier of a dataset.
• start_time: The start time of the request, in ISO-8601 format.
• end_time: The end time (exclusive) of the request, in ISO-8601 format.

from latis.client import read_data

df = read_data(
    "https://lasp.colorado.edu/lisird/latis/dap2",
    "bremen_composite_mgii",
    "2026-01-01",
    "2026-01-02"
)

You can optionally specify an API key for instances that require one.

df = read_data(
    "https://lasp.colorado.edu/lisird/latis/dap2",
    "bremen_composite_mgii",
    "2026-01-01",
    "2026-01-02",
    api_key="<api key>"
)
