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.
