Stationary monitoring is the most commonly adopted method to understand the air pollution levels in India. However, these stations fail to capture local variations in concentration levels. In areas where the emissions and concentrations levels exhibit fine-scale spatial variability, understanding local sources will be key for policymakers to implement effective measures. Sensors installed in mobile platforms have been used to generate evidence at a more granular level. This approach has been used in several countries to supplement existing evidence; however, only limited studies have been carried out in India. This is an 11-month long mobile monitoring study conducted in Bengaluru to produce high-resolution pollution maps of select parts of Bengaluru. The study also examines the feasibility of mobile-monitoring studies in middle-income countries, which often have poor road conditions (making such measurement campaigns challenging), high background pollution levels, and heterogeneous sources of pollution.
