Supporting data for "Dilution for Controlling Airborne Transmission of Infection"

A comprehensive dataset collected during a year-long study of indoor air quality in six air-conditioned environments, focusing on the dilution of infectious aerosols to control airborne transmission. The dataset includes real-time measurements of CO₂ concentrations (as a surrogate for human exhaled aerosols), temperature, humidity, and system intake airflow rates, recorded using a low-cost indoor monitoring system. Data collection spanned diverse settings, including classrooms, catering outlets and offices, with variables such as occupancy levels and activity intensity logged to assess their impact on dilution factors. The methodology involved deploying sensors with a sampling frequency of 1 minute, calibrated against reference standards. This dataset supports research into airborne infection control, offering raw and processed data (CSV format) alongside metadata on sensor placement and environmental conditions. It is intended for use in validating air quality models, informing ventilation standards, and studying pathogen transmission dynamics in built environments.
