This technical note explores the sources of error in gravimetric measurements used for aerosol photometer calibration, emphasizing the impact of discrepancies in aerosol properties, temporal instability, and flawed experimental procedures. It supports the two-point calibration practice to minimize errors, particularly at lower concentrations, and recommends measures such as improved aerosol systems and automation to enhance calibration accuracy. The findings aim to ensure reliable photometer performance for critical applications.
