This project is a Node.js port of the PowderLin.es API. The Ruby on Rails repo is located here.
Use our free API for accessing SNOTEL station data. Our API is useful for finding current snow levels in mountainous regions across the United States. 895 SNOTEL stations are available.
Description: Returns basic information about all of the SNOTEL stations in the United States.
Endpoint: /stations
Request parameters:
| Parameter | Descriptions |
|---|---|
| State | The state to retreive data from. (optional) |
Response parameters: The response comes as an array of objects. Here is a breakdown of a returned object.
| Parameter | Descriptions |
|---|---|
| Name (string) | Name of the station |
| Triplet (string) | Unique identifier for the station. Formatted as ###:STATE:SNTL |
| Elevation (integer) | Elevation of the station in feet |
| Location (lat, lng object) | Latitude and longitude of the station |

]Description: Returns detailed information for the specified SNOTEL station.
Endpoint: /station/:id
Request parameters:
| Parameter | Description |
|---|---|
| ID (triplet) | Station id in the form of ###:STATE:SNTL. Example: 335:CO:SNTL. Find the triplet for a particular station through the /stations endpoint. |
| Days (integer) | Number of days information to retrieve from today. (optional - defaults to 5 unless using start_date and end_date) |
| Start date (YYYY-MM-DD) | Historical date to pull data from. Use in conjunction with end date. (optional) |
| End date (YYYY-MM-DD) | Historical date to pull data from. Use in conjunction with start date (optional) |
Response parameters: The response includes basic station information in addition to an array of snow data.
| Parameter | Description |
|---|---|
| Date | Date measurement was taken |
| Snow Water Equivalent (in) | The amount of water contained within the snowpack. |
| Change In Snow Water Equivalent (in) | The change in the snow water equivalent from the last measurement (typically the past 24 hours). |
| Snow Depth (in) | Depth of snow in inches. |
| Change In Snow Depth (in) | The change in the snow depth from the last measurement (typically the past 24 hours). |
| Observed Air Temperature (degrees farenheit) | The observed air temperature, in degrees farenheit. |

- Thank you to Mr. Marko for creating a great API. It is most definitely something that skiers should use to prepare for a trip into the backcountry.
