A comparison between the weekly maximum proportion of liver condemnation among the cooperatives in three different regions and the predicted potential transmission of L3 (predicted worm) from an infectious reindeer in the respective cooperatives. The vertical dotted black line (> 20%) indicates the threshold for identifying the year with a higher proportion of worm transmission. Note the two Y-axes have different units. The model driven by Finnish Meteorological Institute temperature showed a higher number of L3 being transmitted in 8 of the 10 years (80%) in the southern region, 6 of the 7 years (86%) in the central region and 1 of the 4 years (25%) in the northern region, coinciding with a high proportion of liver condemnation. The model driven by estimated microclimatic temperature showed a higher number of L3 being transmitted in 9 of the 10 years (90%) in the southern region, 6 of the 7 years (86%) in the central region and 2 of the 4 years (50%) in the northern region, coinciding with a high proportion of liver condemnation
