The interpolation-characteristic scheme for the numerical solution of the inhomogeneous
transport equation is constructed. The scheme is based on Hermite interpolation to reconstruction the value of unknown function at the point of intersection of the backward characteristic with the cell edges. Hermite interpolation to regeneration the values of the
function uses not only the nodal values of the function, but also values of its derivative.
Unlike previous works, also based on Hermitian interpolation, the differential continuation of the transport equation is not used to transfer information about the derivatives to
the next layer. The relationship between the integral means, nodal values and derivatives
according to the Euler–Maclaurin formula is used. The third-order convergence of the difference scheme for smooth solutions is shown. The dissipative and dispersion properties
of the scheme are considered on numerical examples of solutions with decreasing
advection equation, interpolation-characteristic method, Hermite interpolation, Euler–Maclaurin formula.
