# xarray.backends.PydapDataStore

### *class* xarray.backends.PydapDataStore(dataset, group=None, session=None, protocol=None, checksums=True)[[source]](https://github.com/pydata/xarray/blob/main/xarray/backends/pydap_.py#L76-L236)

Store for accessing OpenDAP datasets with pydap.

This store provides an alternative way to access OpenDAP datasets that may
be useful if the netCDF4 library is not available.

#### \_\_init_\_(dataset, group=None, session=None, protocol=None, checksums=True)[[source]](https://github.com/pydata/xarray/blob/main/xarray/backends/pydap_.py#L83-L103)

Initialize the data store.

* **Parameters:**
  * **dataset** (`pydap DatasetType`) – The opened pydap dataset.
  * **group** ([`str`](https://docs.python.org/3/builtins/stdtypes.html#str) or [`None`](https://docs.python.org/3/builtins/constants.html#None), *default*: [`None`](https://docs.python.org/3/builtins/constants.html#None)) – The group to open. If None, the root group is opened.
