Plotting Minutely Precipitation using Chart.js

The AerisWeather API makes a plethora of weather data available. Earlier this summer, we introduced minutely precipitation forecasts, one of our latest enhancements to the conditions endpoint. Today, we will look at an easy way to plot minutely precipitation data – which includes snow and rain – using Chart.js. Getting Started We will need to load three javascript libraries. One is the AerisWeather Javascript SDK, and the other two are for our plotting purposes. Note that in order to set up a Time Cartesian Axis in Chart.js, you will need to load a date library. In this example, we will be...

Fall Color Factors, As Explained by Paul Douglas!

Plants convert carbon dioxide in the air into sugars (glucose and starch) and oxygen by using energy from the sun through the process of photosynthesis. Chlorophyll is the green pigment necessary for photosynthesis. A decrease in photosynthesis that comes with less daylight means trees stop producing chlorophyll. As the green pigment fades over time other pigments present in the leaf are revealed, producing a veritable explosion of...
