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

Title: NA3: Linoz Diagnostics

Requirements and Design

NGD Atmosphere

Date: 2019-07-xx

Summary

Requirements

Requirement: (1) update namelist options in the default compset; (2) update size distribution of dust emission fluxes; (3) update the dust emission distribution in the boundary layer

Date last modified: 2019-06-27
Contributors: Yan Feng

The first two updates have been implemented and tested in V1. The third update is implemented and tests are not completed.

Algorithmic Formulations, and Design Implementation

Design Solution:

(1) Change dust optics (dst_a1, dst_a3, dst_c1,dst_c3) in the namelist &cam_inpam to dust_aeronet_rrtmg_c141106.nc

(2) Change fractional emissions in size bins: dust_model.F90. The new dust emission size distribution is calculated based on Kok (2011).
