The FATODE, which is extracted from the KPP numerical libraray, is a Fortran programming library for the integration of stiff ODE systems. It incorporates a set of generic linear solvers suitable for large sparse systems. And the set allows users to add ...

In this paper we present the construction of a standardized adjoint of the global GEOS-Chem model. Adjoint models are powerful tools for estimating the sensitivity of (a function of) the model output with respect to a large number of inputs. The ...

This paper presents a discretization technique for particle dynamics equation based on the B-spline interpolation of the solution. The method is developed in the general framework recently proposed by the authors. Numerical tests include the coagulation-...
