# Action spectrum for the inhibition of phytoplankton carbon fixation

# Spectrum based on
# Boucher, N., Prezelin, B.B., Evens, T., Jovine, R., Kroon, B., Moline, M.A.,
# and Schofield, O., 
# "Icecolors '93: Biological weighting function for the ultraviolet
#  inhibition  of carbon fixation in a natural antarctic phytoplankton community", 
# Antarctic Journal, Review 1994, pp. 272-275, 1994.

# The same spectrum is also parameterized  in:
# N.P Boucher, B.B. Prezelin,
# "An in situ biological weighting function for UV inhibition of phtoplankton 
# carbon fixation in the Southern Ocean",
# Marine ecology progress series, Vol 144, 223-236, 1996.
# Equation 7 on page 231, with coefficients for the 
# "chl-specific function epsilon*" given in units of
# [(mg C) * (mg chl)^-1 * (J m^-2)^-1]:

# epsilon*  = -3.17E-6 + exp(112.5 - 6.223E-1 * w + 7.670E-4 * w^2)
# w is wavelength in nm.

# The parameterization is the same as used in the subroutine pbiol1.f of the
# radiative transfer code "TUV", available at www.acd.ucar.edu/TUV/

# Note: Solar spectra of the NSF UV monitoring network are provided in 
# units of [uW/cm^2 nm]. 
# Spectra weighted with the values given below therefore have the units:
# [uW / cm^2 * (mg C) * (mg chl)^-1 * (J m^-2)^-1]
# Published values were multiplied with 0.01 and are reported in
# units of [(mg C) * (mg chl)^-1 * s^-1]

# Integration range: 290 - 368.4 nm
# (The function becomes negative at wavelengths >=268.5 nm and it was 
# therefore set to 0)

# Column 1 is wavelength
# Column 2 is response in [(mg C) * (mg chl)^-1 * (J m^-2)^-1]
