This is a plot of viscosity vs temperature for the NASA and Wind-US curve fits for N2. For the NASA curve fit the viscosity increases almost linearly from about 0.4 at 1000 K, to just under 1.2 at 5000 K. The viscosity from the Wind-US curve fit is very nearly the same, matching the NASA curve fit values at the end points, and slightly higher in between.
