Aethalometer data processor

Version 20181101

Data acquired from filter-based measurement such as Aethalomenter needs carefully correction due to its inherent systemic error, i.e., filter matrix effect, scattering effect and loading effect. The non-linear relationship between  (light attenuation on the filter) and  (light absorption coefficient of suspended aerosol in ambient air) has become a challenge for Aethalomenter, as a linear relationship is assumed by default in its output data. This program applies Weingartner (2003) and Virkkula (2007) algorithm to correct the data. QA/QC features are also provided, including statistics of sensor voltage.

================================================================================================

从基于膜采样的测量获得的吸收系数数据(例如Aethalomenter)需要仔细校正,因为其固有的系统误差,包含采样膜的matrix效应,散射效应和载荷效应。 (采样膜上的光衰减)和 (环境空气中悬浮的气溶胶的光吸收系数)之间的非线性关系已成为Aethalomenter的挑战,因为在其输出数据中默认地假设为线性关系。 该程序应用Weingartner(2003)和Virkkula(2007)算法来校正数据。 还提供QA / QC特性,包括传感器电压的统计等信息。
