Atmospheric Monitoring

Atmospheric monitoring involves tracking and analyzing the quality of air in outdoor environments to understand pollution levels, weather patterns, and climate changes. This process helps identify pollutants such as particulate matter (PM2.5 and PM10), sulfur dioxide (SO₂), nitrogen oxides (NOx), ozone (O₃), and carbon monoxide (CO). Regular atmospheric monitoring is crucial for urban planning, environmental policy, and ensuring public health.

• Key Applications: Weather forecasting, air pollution studies, public health assessment, compliance with environmental regulations.
• Common Sensors Used: PM2.5/PM10 sensors, CO sensors, NOx sensors, O₃ sensors, and SO₂ sensors.

Indoor Air Quality Monitoring

Indoor air quality (IAQ) monitoring focuses on measuring the concentration of pollutants inside buildings, such as homes, offices, factories, and public spaces. Monitoring IAQ is vital for maintaining a healthy indoor environment, as poor air quality can lead to health issues like allergies, respiratory problems, and headaches. Key pollutants include carbon dioxide (CO₂), volatile organic compounds (VOCs), humidity, temperature, dust particles, and formaldehyde (HCHO).

• Key Applications: Ensuring healthy workspaces, maintaining indoor comfort, HVAC system optimization, and preventing Sick Building Syndrome (SBS).
• Common Sensors Used: CO₂ sensors, VOC sensors, temperature and humidity sensors, PM2.5 sensors, and formaldehyde sensors.

Pollution Source Monitoring

Pollution source monitoring focuses on identifying and measuring pollutants emitted directly from industrial processes, transportation, power generation, and waste disposal. This type of monitoring helps industries comply with environmental regulations, reduces environmental impact, and ensures that emission levels remain within permissible limits. Common pollutants include greenhouse gases (GHGs) like CO₂, methane (CH₄), NOx, sulfur oxides (SOx), and particulate matter.

• Key Applications: Industrial emission control, regulatory compliance, identifying pollution hotspots, and optimizing emission-reduction strategies.
• Common Sensors Used: Gas analyzers for CO₂, CH₄, NOx, and SOx, particulate matter sensors, and continuous emission monitoring systems (CEMS).
