Light Flux Characterization #20 - 2013-12-16
LICOR Spectroradiometer (#354)
Date of characterization experiment:
Months since calibration:
The instrument measures the irradiance, which is then converted to flux
Photolysis frequency of NO2 with max lighting [Hz]:
Photolysis frequency of H2O2 with max lighting [Hz]:
Photolysis frequency of O3 with max lighting [Hz]:
Total number of lights:
Light percentage on:
Light source type:
UV black lamps (350 nm centered)
Position and pattern of lights:
Lights are positioned on the long side of the chambers. There are UV-reflective aluminum all around the chamber, such that the flux in one corner is similar to the middle.
Data collection description:
Data were collected as an average of several locations in the chamber.
Data analysis description:
Averaged data in W/m2 were converted to photon flux and scaled by the H2O2 photolysis in a modeling program that uses the most up-to-date H2O2 absorption cross section.
