Hi,

Could you please provide information on the wavelength at which the product ‘fine particles light scattering’ (unit: Mm⁻¹) provides data? Is it 880 nm, 370 nm, or another wavelength?

It is red or near IR, not near-UV. There are many papers out there that get into the weeds on what the PA is and does. Ouimette-Evaluating the PurpleAir monitor as an aerosol light scattering instrument_AMT2022 is an open source example. Also Ouimette-Fundamentals of low-cost aerosol sensor design and operation PA_AST2023.
