Ed Hawkins’ Local weather Stripes visualization of worldwide heating has shortly turn out to be a knowledge visualization traditional. Local weather Stripes (generally generally known as Warming Stripes) are a visible illustration of the long-term improve in international temperatures on account of local weather change. Ed’s hanging Local weather Stripes visualizations encompass coloured vertical stripes, with every stripe representing a single yr and the colours indicating the temperature anomaly for annually relative to a baseline interval.

Impressed by Local weather Stripes Edinburgh College has created Air High quality Stripes visualizations for various international cities. Air High quality Stripes use coloured stripes to point common yearly air air pollution ranges in cities since 1850. Like Ed Hawkins’ Local weather Stripes these Air High quality Stripes are efficient in offering a easy and simply understandable visualization of historic traits in a given dataset.

Every metropolis’s Air High quality Stripes can immediately convey the historical past of air high quality in a metropolis. For instance, as Edinburgh College notes, the stripes display “the air in lots of cities in Europe is way cleaner now than it was 100 years in the past.” In distinction (as you may see within the screenshots above) the air high quality in lots of Indian cities has turn out to be dangerously worse within the twenty first Century.

Edinburgh College really offers 4 several types of yearly air air pollution ranges for every metropolis. Regardless of the effectiveness of the air air pollution stripes visualization of the info I really want the extra conventional bar graph visualizations of the identical knowledge. These bar chart visualizations of yearly PM2.5  concentrations embody reference traces to point out the WHO Guideline (a goal of a focus of 5 micrograms om PM2.5 per cubic meter) and Edinburgh College’s personal ‘Very Poor Air High quality’ stage. Alongside the usage of colour the peak of every yr’s bar offers a further information to the typical ranges of air air pollution.
