    Real-Time PM2.5 Heatmap Generation API using IDW and CAMS Data
    Python

    This project implements a high-performance FastAPI-based web API for generating and serving PM2.5 air quality heatmaps. It uses CAMS (Copernicus Atmosphere Monitoring Service) PM2.5 data stored in a PostgreSQL database and applies Inverse Distance Weighting (IDW) interpolation to visualize spatial air quality patterns. The resulting interpolated maps are converted to images, encoded in base64, and served via API for web use (e.g., dashboards, apps).

    Smart Sensor Deployment: Optimizing Air Quality Monitoring with Python
    Python

    In the fight against air pollution, strategic placement of air quality sensors is crucial. What if you could automatically determine the best spots to deploy sensors across a city—ensuring spatial coverage, avoiding water bodies, and hitting every key urban category?Introducing the PolygonSensorOptimizer, a Python class designed to do exactly that.

    Bridging the Skies and Streets: Integrating Stationary AirQo Sensors with Satellite AOD Data for Cleaner Air Insights
    Python

    In the ever-evolving fight for clean air, the fusion of ground-based air quality sensors with satellite-derived data opens a new frontier of insights. At the heart of this integration lies an exciting workflow that combines AirQo’s stationary sensor data with NASA’s MODIS Aerosol Optical Depth (AOD) imagery, all powered by Google Earth Engine and Python.This blog walks you through how we blend these two powerful data sources to uncover deeper patterns in air pollution, especially fine particulate matter (PM2.5), across African cities like Fort Portal

    Enhancing Mobile Air Quality Readings Using Stationary Sensor Data: A Distance-Aware Matching Approach in Python
    Python

    In urban air quality research, mobile monitoring has emerged as a powerful approach to capturing hyperlocal pollution patterns. However, mobile sensors often lack critical environmental context such as temperature, humidity, wind speed, and stationary PM2.5 values, information typically captured by stationary monitors.

    Optimizing Urban Air Quality Monitoring Networks: A Multi-Method Approach for Spatial-Temporal Efficiency and Cost-Effective PM2.5 Surveillance in Kampala, Uganda
    Python

    This study proposes a multi-method optimization framework to enhance the network’s efficiency. First, spatial distribution analysis employs spatial autocorrelation (Moran’s I, Getis-Ord Gi*) and Voronoi diagrams to evaluate coverage gaps and redundancies.

    Site Categorization API Project
    Python

    The Site Categorization API is designed to classify locations based on their geographical and environmental characteristics using OpenStreetMap (OSM) data. The API helps categorize sensor deployment sites by considering factors such as land use, proximity to natural features, and road classifications.
