tensogram-xarray 0.20.0

xarray backend engine for tensogram .tgm files

Tensogram xarray Backend

xarray backend engine for Tensogram .tgm files — open a Tensogram message or file as an xarray.Dataset with the native engine="tensogram" hook, including Dask-backed lazy loading.

Installation

pip install tensogram-xarray
# or, with Dask-backed lazy reads
pip install "tensogram-xarray[dask]"

The tensogram native package is pulled in automatically.

Usage

import xarray as xr

ds = xr.open_dataset("forecast.tgm", engine="tensogram")
print(ds)                    # coordinates, variables, CF attributes
print(ds["temperature"])     # standard xarray DataArray

With Dask for out-of-core reads:

ds = xr.open_dataset("forecast.tgm", engine="tensogram", chunks="auto")

Multi-message files open as a single merged Dataset; coordinates and dimensions are inferred from CF-style metadata when present.
