This interactive notebook explores how air quality has changed since the beginning of the year and how effective specific policies have been at driving pollution reductions.* Humans have impacted the planet for as long as they've lived on it, which can be difficult to see in our day-to-day lives. But quarantine has become the new normal in the face of a global pandemic, and the absence of these impacts has made them easier to comprehend than ever: with cars off the road and people out less, bodies of water are cleaner, the world is quieter, and the air is fresher. And this phenomenon is more than just a feeling reported by people going on the occasional leisurely walk—data gathered by the [World Air Quality Index (WAQI) Project](https://waqi.info/) suggests that in most countries, air quality has improved anywhere from slightly to drastically since the outbreak of COVID-19. WAQI is a non-profit project that was launched in 2007 to provide citizens in 1000 cities around the world with information on local air quality. Though raising awareness of air pollution and how it differs from city to city is already critical, this dataset’s existence has reached new levels of importance in the age of COVID-19, as people seek to understand the impacts of the pandemic on all facets of their lives. Air quality is typically recorded as a single value known as an Air Quality Index (AQI), which ranges from 0 to as high as several hundred. It represents the level of air pollution outdoors, and is usually based on the concentrations of several key pollutants in the air—particulate matter (PM2.5 and PM10), sulfur dioxide, nitrogen dioxide, ozone, and carbon monoxide. Lower AQI values correspond to better air quality, and higher AQI values imply that certain groups, such as children and people with respiratory troubles like asthma, are at risk of experiencing negative health impacts. The highest AQI values suggest that everyone is at risk and should limit any time spent outdoors. As most countries in the WAQI dataset monitor PM2.5 levels, the AQI values used in this project are based solely on PM2.5 concentrations. `4e:T475,md` | AQI(PM2.5) | Air Quality | Implications | | -----------| -------------- | -------------- | | **0-50** | Good | The air quality is good, and air pollution presents few, if any, health risks.| | **51-100** | Moderate | The air quality is okay, but not ideal. Depending on pollutant concentrations, going outside may pose health risks to those with sensitive respiratory systems. | | **101-150** | Unhealthy for Sensitive Groups | Active people and those with respiratory diseases should limit the time they spend outside. | | **151-200** | Unhealthy | Sensitive groups and active people should refrain from exerting themselves outdoors; all groups—and especially children—should limit the time they spend outside. | | **201-300** | Very Unhealthy | With prolonged exposure to the air, everyone is at risk of experiencing major health effects. | | **300+** | Hazardous | Everyone faces serious health risks and should stay inside.| `4f:Ta68,chartp1 = { const svg = d3.create("svg") .style("display", "block") .attr("viewBox", [0, 0, widthp1 + 25, heightp1 + 25]); const defs = svg.append("defs"); defs.append("path") .attr("id", "outline") .attr("d", path(outline)); defs.append("clipPath") .attr("id", "clip") .append("use") .attr("xlink:href", new URL("#outline", location)); const g = svg.append("g") .attr("clip-path", `url(${new URL("#clip", location)})`); g.append("use") .attr("xlink:href", new URL("#outline", location)) .attr("fill", "#edfbff"); let animationstate = testp1.b.textContent var div = d3.select("body").append("div") .attr("class", "tool-tip") .style("opacity", 0); g.selectAll("path") .append("g") .data(countriesp1.features) .join("path") .attr("fill", d => color(currentDatap1.get(d.properties.name))) .attr("d", path) .on('mouseover', function(d, i) { if(animationstate == "Play"){ d3.select(this).transition() .duration('50') .attr('opacity', '.75'); div.transition() .duration(50) .style("opacity", 1); div.html(`${d.properties.name}

To do this, we join the data from WAQI with information from [The Oxford COVID-19 Government Response Tracker (OxCGRT)](https://www.bsg.ox.ac.uk/research/research-projects/coronavirus-government-response-tracker) in the next two sections.\n\nOxCGRT systematically collects information across 17 different indicators that track common government policy responses to COVID-19. It has data from more than 160 countries. Some indicators record economic policies and others show health system policies, but we focused on the eight policy indicators that record containment and closure policies (C1-C8), such as closing schools and issuing \"stay at home\" requirements.\n\nWhen considering this data in conjunction with the AQI data, we are interested in the relationship between AQI data and policy decisions.`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":129,"value":"md`### [Part II: Government Policies by Country](https://observablehq.com/@joanneho14/part-2-comm277-final-project)`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":381,"value":"md `In this section, we are interested in finding case examples that demonstrate that country pollution levels decreased significantly chiefly after government policies to slow or shutdown the economy were enacted.\n \n*In the interactive graph below, select from the dropdown list the country you would like to analyze in further detail.
