Wall loss experiment description:
For a few experiments, optimize parameters using just coagulation and particle-wall deposition. Also, verify optimization for each experiment for the background period prior to photolysis.

Wall loss rates calculation method:
Optimization for ke and E

Frequency of particle loss experiments:

Wall loss correction description:

Additional notes:
This only let me upload data for one day's experiment, but there were a few days that contributed to the wall loss parameters
