The current indicators for this project mostly consider traffic volume as a major \ncontributor to air pollution. \n\n# General Trends and Map Overview \n\nWe can begin by plotting the changes in NO2 levels across NYC from 2008 to 2021. This creates a general plot highlighting discernible cyclical patterns.\n\n![averageNO2Levels](https://github.com/halaway/nyc-air-quality-analysis/assets/31904474/8e786784-62a7-4b8c-9774-f9985ff0ad31)\n\n\n\nMapping historical NO2 levels by Community Districts and aggregating by the average level\nin a 12-month period could help to assess any changes in NO2 and emerging patterns within our data.\n\nThe following procedure creates a choropleth map of NYC with respect to time and is available here:\n\n[Change in NO2 Levels in NYC from 2008-2022](https://tinyurl.com/2e3m8779 )\n\n\n# Machine Learning Models\n\n## K-Means Clustering\n\nClustering multi-polygons with varying levels of Nitrogen Dioxide in 2020 produced the following clusters: \n\n![kmeans_NYC_2020](https://github.com/halaway/nyc-air-quality-analysis/assets/31904474/a2e7c14d-9304-4fd0-a389-8178c4e73d2f)\n\nHowever, focusing only on our data from 2010, we can create 10 clusters for grouping Community Districts based on \naverage NO2 levels and an aggregation of Traffic Volume per locale. \n\nThis creates the following clusters: [Available Here](https://olive-susana-62.tiiny.site/) \n\n\u003cimg width=\"878\" alt=\"Screen Shot 2023-11-18 at 12 39 38 AM\" src=\"https://github.com/halaway/nyc-air-quality-analysis/assets/31904474/f1b5429e-9136-4555-a7bd-445f555e0227\"\u003e\n\n\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhalaway%2Fnyc-air-quality-analysis","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhalaway%2Fnyc-air-quality-analysis","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhalaway%2Fnyc-air-quality-analysis/lists"}
