Web-based Snowpack Visualization Toolkit

Mt. Washington Avalanche Center

Project Overview

The Mt. Washington Snowpack Visualization App is a Python-based web application designed to provide an interactive and comprehensive view of the snowpack data collected by the Mt. Washington Avalanche Center (MWAC). This application integrates historical data from the Hermit Lake snowplot along with real-time field observations collected by the Avalanche Center staff, offering a valuable tool for researchers, climbers, and enthusiasts interested in the snow conditions of Mt. Washington.

Features & Product Requirements

Product Features:

• Interactive Data Visualization: Utilizes Streamlit for an intuitive and interactive user interface.
• Historical Data Analysis: Access to historical snowpack data from the Hermit Lake snowplot.
• Real-time Observations: Integration of current field observations by the Avalanche Center staff.
• Customizable Views: Options to filter and analyze data based on various parameters.
• Responsive Design: Ensures compatibility with various devices and screen sizes.

Product Requirements: The user can select to plot a time series of one or more variables

• The user can alter the lookback window; from 1 day to entire winter
• The user can download all source data with a single click (ideally, able to filter certain years)
• The user can compare the current winter against the previous winter

Service Definition (OpenAPI v3.0/Swagger): https://api.weather.gov/openapi.json

1. Retreive metadata from the KMWN station at the Mount Washington Summit here: https://api.weather.gov/points/44.27028000000007,-71.30332999999996

2. Receive a JSON document and find the forecast property inside the properties object

   • Find the hourly forecast from the forecastHourly property and retrieve that URL:
   • Example: https://api.weather.gov/gridpoints/GYX/37,81/forecast/hourly

Gridpoint data information:

• Document contains data about the forecast grid, with multiple layers of data
• The data is presented as a time series, in an hourly format

Relevant available data layers:

• temperature
• dewpoint
• maxTemperature
• minTemperature
• relativeHumidity
• skyCover
• windDirection
• windSpeed
• weather
• quantitativePrecipitation
• snowfallAmount
• snowLevel
• iceAccumulation
