Andrews Forest LTER PurpleAir Visualizer and Dataset

PurpleAir Visualizer is a desktop application designed for the exporator data analysis of air quality data collected by PurpleAir sensors. This tool enables researchers, environmental scientists, educators, and community scientists to load, inspect, and visualize particulate matter (PM2.5) data. The application features Air Quality Index (AQI) conversion capabilities, allowing users to translate raw PM2.5 measurements into standardized AQI values using EPA guidelines. Key features include: Interactive graphical interface for data exploration Support for loading and previewing PurpleAir CSV data files Flexible plotting options, including time series and subplots Automatic detection and conversion of PM2.5 data to AQI with color-coded visualizations Export of plots as high-quality PNG images for reports and presentations Included Data: The program package comes with a dataset: hourly PurpleAir data from sensor #115739, located at the H.J. Andrews Experimental Forest Long Term Ecological Research (LTER) site. This real-world dataset provides users with an opportunity to explore and visualize air quality measurements from a research field station, the HJ Andrews Experimental Forest.
