Summary
New systems for continuous atmospheric aerosol and reactive gas sampling ensure accurate air quality monitoring. These low-cost, smart systems meet World Meteorological Organization standards for reliable data collection.
Area of Science:
- Environmental Science
- Atmospheric Chemistry
- Air Quality Monitoring
Background:
- Accurate atmospheric aerosol (AE) and reactive gas (RG) observations are crucial for near-surface monitoring networks.
- Minimizing sampling artifacts is essential for reliable ambient air composition data.
Purpose of the Study:
- To develop novel, low-cost systems for continuous ambient air sampling.
- To ensure AE and RG measurements comply with WMO/GAW and ACTRIS standards.
Main Methods:
- Development of "smart" sampling systems with controlled flow rates and temperatures.
- Implementation and year-long operation analysis at a WMO/GAW regional station (Capo Granitola, Italy).
Main Results:
- The developed systems effectively stabilize and control sampling flow rates and temperatures.
- One year of operation demonstrated the systems' capability to meet technical requirements.
Conclusions:
- The novel sampling systems are effective for accurate AE and RG measurements.
- These systems support reliable near-surface air quality monitoring according to international standards.
