Climate Data Sets
SNOTEL
SNOTEL (SNOw TELemetry network) data are available for download from the automated snow monitoring program administered by the Natural Resources Conservation Service (NRCS) and the National Water and Climate Center. To find and extract SNOTEL data, click on the Map Tools icon and select Extract Data. Click on Climate and then select SNOTEL.
- An Extract: pop-up window will open allowing a search to Find station by name or keyword:. Type the name or keyword into the box and then select from the choices in the Add map region to search: box. See below for options:
- The Current Map Extent can be used as a larger search area.
- Point or Line buffers can be specified by setting a buffer radius in the units specified in the map settings.
- Polygon or Rectangle areas can be selected and then delineated on the map by clicking and moving the cursor to the next vertex and clicking, then double-clicking when done to define the shape.
- The search can occur Within Layer Extent: by choosing an existing layer from the drop down menu and further specifying which part of the layer from the second drop-down menu.
- Known Boundary: uses a State, County, City, or HUC (hydrologic Unit Code) boundary for the search area.
- Once the map region to search is defined, click Submit and then Next to view the results of the search. In the Select Station(s) pane, any stations that were found in the previously defined map region will be displayed. If no stations were located, none will be listed.
- Click on a station to display its location on the map and a pop-up dialog box with general and locational information about the station.
- To select more than one station hold down Shift while clicking on multiple stations.
- To go back to the Station Search pane if needed, click Previous or click on the pane name on the left side of the pop-up window.
- To clear the search, either click Clear by the search box or Reset Search below the map region specification box.
- To refine the data to be downloaded, click on the Advanced link at the bottom of the window or Next to proceed to the Advanced Options pane. Here, a specific period of record can be selected by completing the Begin Date: and End Date: boxes. When complete, click Download.
- A Download Time Warning pop-up box will display declaring that the download may take a while. Click Download to proceed or Cancel to cancel the operation. Make sure pop-ups from eRAMS are not blocked. When the process is complete, a zipped data file will automatically be downloaded which can be extracted to .csv format. All available parameters are included in the download file.
