The Design Document page provides a description of the algorithms, implementation and planned testing including unit, verification, validation and performance testing. Please read Step 1.3 Performance Expectations that explains feature documentation requirements from the performance group point of view.

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

Title: Gustiness (representation of subgrid surface winds)
Requirements and Design
E3SM Atmosphere Group
Date:
Summary
The gustiness formulation from v1 has been modified to allow to be applied globally (over land and ocean instead of restricted to ocean only) and also to include the the effect of large eddies from CLUBB. These winds are added to the resolved-scale winds in the calculation of surface exchange of heat, moisture, and momentum.
Requirements
Requirement 1: Calculation of marine organic emissions from offline fields produced from marine biogeochemistry models
Three pull requests incorporate the gustiness: 2679 adds the main functionality; 2720 removes the previous implementation; 2789 adds namelist changes for EAMv2.
