Design Document

The first table in Design Document gives overview of this document, from this info the Design Documents Overview page is automatically created.

In the overview table below 4.Equ means Equations and Algorithms, 5.Ver means Verification, 6.Perf - Performance, 7. Val - Validation

  • Equations: Document the equations that are being solved and describe algorithms
  • Verification Plans: Define tests that will be run to show that implementation is correct and robust. Involve unit tests to cover range of inputs as well as benchmarks.
  • Performance expectations: Explain the expected performance impact from this development
  • Validation Plans: Document what process-based, stand-alone component, and coupled model runs will be performed, and with what metrics will be used to assess validity

Develop input data to support the implementation of subgrid topography in ALM and CAM

This task includes:

1) Testing two approaches to represent subgrid topography (elevation, slope, and aspect), select an optimal approach to balance the ability to capture subgrid variability of topography with computational efficiency.

2) Discuss with the land and atmosphere team the selection of approaches to inform the design of model data structure and coupling method to support the implementation of subgrid topography in ALM and CAM.

3) Develop input datasets needed to implement subgrid topography in ALM and CAM. These include (a) delineation of watersheds at 1/8 degree resolution (for the original design), (b) fractional area, mean elevation, slope, and aspect of each subgrid topographic landunit within each model grid (which can be the 1/8 degree watershed or the CAM-SE grid), (c) dominant soil texture for each subgrid topographic landunit, (d) fractional area of each PFT within each subgrid topographic landunit, (e) elevation profile within each subgrid topographic landunit to support inundation modeling, and (f) information needed to map between the ALM and CAM subgrid topographic classes (not needed for the fallback plan in which CAM and ALM share the same grid and subgrid topographic landunits).
