Roadside Monitoring in India for Traffic Emission Management

Sector：Traffic and Marine Emission Monitoring

Location：India, Mumbai

In India, road transportation serves as the primary mode for both goods delivery and passenger travel. The country's extensive road network, stretching across 4.7 million kilometers, significantly enhances the quality of life for citizens and promotes economic growth. However, the environmental and health risks associated with vehicular emissions cannot be overlooked. To advance the understanding of vehicle emission factors in India, Harish C. Phuleria from the Indian Institute of Technology Bombay has deployed Sapiens's high-performance, cost-effective sensors along the Panch-Shrishti-Comp

Tethered Balloon Deployment of Sapiens Air Sensors for Planetary Boundary Layer Research at High Altitude

Sector：Ambient and community

Location：Shanghai, China

New particle formation (NPF) is a significant source of atmospheric aerosols, playing a crucial role in influencing global climate. The nucleation and subsequent growth processes involved in NPF have sparked considerable research interest. To advance the study of NPF in China, researchers employed the high-performance MAS series to measure air quality at elevations exceeding 1000 meters. This investigation focused on the vertical profiles of key pollutants and their formation mechanisms, providing valuable insights into atmospheric dynamics.
