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: UNICON convection

Requirements and Design

ACME Atmosphere Group
 Group

Date:  

Summary

The goal of this task to implement and evaluate a new convective parameterization scheme - UNified CONvection scheme by Sungsu Park (Unlicensed) at NCAR in ACME. There are noticeable improvements using UNICON in terms of mean climate, climate variabilities including Madden Julian Oscillation (MJO) and diurnal cycle of precipitation, and so on. We want to implement this new scheme into the ACME master and do series of evaluations. 

Requirements

Requirement 1: Fast track implementation and evaluation were done successfully.  We found a couple of implementation errors and fixed.  Also, we found an issue with new tracers in UNICON and SE dycore.  A fix was implemented.

Requirement 2: Slow track implementation is discussed.
