We perform a wide array of services and analyses. Below are our most common services. Each job is tailored to your needs. If you’re not sure whether we can support your modeling needs, please contact us.

Boundary Conditions and Standard Model Output

GEOS-Chem is capable of providing 3-D dynamic representations of atmospheric composition worldwide. These fields are commonly used as boundary conditions for high-resolution regional models and for regional and global atmospheric chemistry & air-quality studies.


Sensitivity Simulations

Sensitivity simulations consist of a standard and a perturbed model simulation. Interpretation of the differences illuminates the impact of a prescribed change on atmospheric composition.


Adjoint sensitivity simulations

The GEOS-Chem adjoint model operates in a time-inverted manner, providing the sensitivity of a given quantity (often an observation) to processes earlier in time. For example, the GEOS-Chem adjoint can efficiently estimate the factors that contributed to a high pollution event measured at a given location or area.

Geoscientific Code Auditing

Geoscientific code can be large, opaque, and generally overwhelming to use. We offer a comprehensive analytical audit of scientific code to uncover bugs, validate and improve model performance, assure the code conforms to best practices, and document scientific traceability.
