Introduction
1. Overview of the standardization of aerosol observation terminology
Atmospheric aerosol is an important component of the environment, and its observation and research require a unified terminology system. This standard provides standardized terminology definitions for scientific research, business and teaching activities.
2. Comparison of standard frameworks
| Dimensions | This standard | International standard ISO | Industry standard comparison |
|---|---|---|---|
| Term definition | Aerosols and their physical and chemical properties are defined in detail. | ISO 4225:1994 provides a basic framework. | Highly consistent with domestic environmental monitoring standards. |
| Classification system | Includes primary aerosol, secondary aerosol, etc. | Covering natural and anthropogenic sources. | In line with global climate change research. |
| Measurement methods | Standardize a variety of sampling and analysis techniques. | Recommend internationally used monitoring equipment. | Optimize in combination with local needs. |
3. Implementation recommendations
Data collection and processing
- Give priority to active sampling methods (membrane sampling, impact cutter).
- Integrate online monitoring equipment (such as < b class=instrument>TEOM and QCM) to improve data accuracy.
Quality Control
- Regularly calibrate instruments to ensure that measurement errors are within the allowable range.
- Establish a data review mechanism to eliminate abnormal values.
