# Working with Rain Gage nodes

A Rain Gage node can be located anywhere on the map - you will specify in your Subcatchment nodes which Rain Gage should be used.

The Rain Gage node **Properties Window** is shown below.

Click in the **Name** field, type a new name and press the Enter key on your keyboard to adjust the label provided to your rain gage. This is populated by default based on values set on the **Model Defaults** window, recall how to edit these defaults from the [Urban Networks](/v1/docs/1d-urban-networks) section.Note that if you change the name of a node, this label will be automatically updated in any connecting links so there is no further work to be done.

The **X-coordinate** and **Y-coordinate** are automatically filled based on the node icon location in the **map** view. Note again, this can be located anywhere on the map - you will specify in your Subcatchment nodes which Rain Gage should be used.

A **Description** and/or **Tag** can be optional provided. You may find tags helpful to group components together - this can be a way to categorise specific nodes. To edit these, click in relevant the field, type a new value, and press the Enter key.

The **Rainfall format** must be provided. Use the dropdown provided to select the type of rainfall data from INTENSITY, VOLUME or CUMULATIVE, and the time interval of this data.

A value can be provided to take **Snow Catch** into consideration. This factor will be set to 1.0 by default.

A **Data Source** must be selected from the dropdown and two options are provided for this. The **Timeseries** option requires a **Series Name** to be specified in the **Timeseries** fields below. The field will show with a * initially. You can select a pre-defined series if you have one available, or define a new series.

Defining and editing a time series is performed in the same way to as described in [How to define direct inflow](/v1/docs/how-to-define-direct-inflow-for-an-urban-junction-node), and we refer to user here for further details on this method.

The **File** options requires additional parameters to be provided in the **Data File** fields below. We refer the user to the [Urban Rain Gage Node](/v1/docs/the-urban-rain-gage-node) section of the technical reference for further details on this method.
