Instrument - LICOR Spectroradiometer
LICOR light flux
What is being measured:
Data recording software:
Data analysis software:
Raw data time resolution:
Analysis data averaging:
Sensitivity to temperature (and correction method, if applicable):
Sensitivity to relative humidity (and correction method, if applicable):
Sample preparation method:
Sample residence time (chamber to instrument) (seconds):
Length of tubing (cm):
Instrument flow rate:
Tubing inner diameter:
Chemical identification method:
Data analysis method:
Multiple measurements were taken, which were then averaged and converted to flux via the equation F (ph/cm2/nm/s) = 4*Irradiance/(Ephoton), where the factor of 4 is the ratio of the flux impinging on a sphere over the circular cross section of the cosine corrector.
Scaled by H2O2 photolysis frequency and OH rate of hydrocarbon decay.
Calibration drift estimate:
Uncertainty estimation method:
Uncertainties are based on deviations in measurement precision and error in the application of scaling factor.
