Name:
light flux characterization

Instrument ID:
HIAPER Airborne Radiation Package (#382)

Chamber:
NCAR 3rd Floor Teflon

Date of characterization experiment:
2016-02-18

Months since calibration:

Measurement technique:
To characterize photolytic conditions in the chamber, irradiance spectra were collected in the wavelength range of 180–600 nm at ~0.8 nm resolution by a custom-built spectroradiometer (Petropavlovskikh et al., 2007).

Photolysis frequency of NO₂ with max lighting [Hz]:
787.4

Photolysis frequency of H₂O₂ with max lighting [Hz]:

Photolysis frequency of O₃ with max lighting [Hz]:

Total number of lights:
128

Light percentage on:
100

Light intensity:

Light source type:
32W, Type F32T8/BL

Position and pattern of lights:
surrounding four sides of the bag

Data collection description:
Data are collected by placing the custom-built spectroradiometer on the center of the chamber in the absence of the bag.

Data analysis description:
Data were processed with custom built software.
