# Average Biological Weighting function for UV inhibition of 
# photosynthesis in Antarctic phytoplankton						

# Based on measurements of phytoplankton from the Southern ocean 
# (McMurdo Sound, Anvers Harbor, Weddell-Scotia Confluence)
# Integrated weighted irradiance is dimensionless and is applied
# to estimating photosynthetic rate using the relationship Prelative = 1/(1+Einh)
# where Prelative is photosynthetic rate over a 1 hour exposure
# relative to the rate under PAR alone, Einh is weighted irradiance.
# Shape and amplitude of the function varies between populations so
# that actual effects can vary strongly from this estimate.
# Effects over other time periods depend on the kinetics of
# UV inhibition which differ between populations

# Spectra weighted with the values given below therefore have the units:
# [uW / cm^2 * (mW m^-2)^-1]
# Published values were multiplied with 10 in order to become dimensionless.
