Hendrickson - Klughammer and Schreiber’s simplified lake model quenching
equations
Y(II) = (Fms -Fs)/Fms or )Fm’/ Fm’
Y(NO) = Fs/Fm or F/Fm
Y(NPQ) =( Fs/Fms)-Y(NO) or (F/Fm’) - Y(NO)
NPQ= Y(NPQ)/Y(NO) or NPQ = (Fm-Fm’)/Fm’

Relaxation test for Hendrickson Klughammer and puddle model
q
E = ((Fme-Fms)/(Fm-Fms)) is the relaxation saturation value
at four minutes in the dark. (Values can be changed in Excel).
q
T = ((Fmt-Fme)/ (Fm-Fms)) is the relaxation saturation value at
twenty minutes in the dark. (Values can be changed in Excel).
