You can approximated the MIL 55310 between two points in time as f(t2) - f(t1) = Aln(t2/t1) A = ( f(t2) - f(t1) )/ln(t2/t1) Looking at some of your plots it looks like between the end of year 1 and year 10 you age from 20 ppb to 65 ppb, A ~ 20 The next plot "Lars_ForceAcoef", is a fit with the A coefficient forced to be 2 and 20.

(Town Beach) Observation date: 10/26/10 Number of species: 27 Mourning Dove 3 Red-bellied Woodpecker 2 Yellow-bellied Sapsucker 1 Downy Woodpecker 2 Hairy Woodpecker 2 Pileated Woodpecker 2 Blue Jay 4 American Crow 4 Common Raven 2 Black-capped Chickadee 12 Tufted Titmouse 4 White-breasted Nuthatch 1 Brown

Among 7 people who visited and helped out were Seigne and Leif Novrup, visiting from Denmark. Leif is the "Osprey record keeper" for Denmark, although they have very few OS in the country, and he helped spot several birds. They were very interested in our raptors, since they don't have most of them at home. Don Morgan Coventry
