Abstract: |
Atmospheric
models represent the state of the environment including interactions that
occur in the atmosphere and are thus useful to predict future temperature
distributions and concentration densities of important species. A prominent
example of an atmospheric model, specialized for the thermosphere, is the
MSIS-86 model developed at NASA. In this note, we describe transforming this
computer program by means of the automatic differentiation tool ADIFOR to
obtain a new computer program capable of evaluating the derivatives of the output
of MSIS-86 with respect to its input. These sensitivities are quantified and compared with derivatives approximated by divided differencing, demonstrating the
reliability of automatic differentiation. |
