Abstract

The satellite simulators are developed to facilitate direct comparison of modeled clouds with detailed observations. For the ACME project, the cloud diagnostics from simulator output were added in UVCDAT and the Tier 1b cloud collection has been implemented to the diagnostics package in the UVCDAT framework. In addition, a ground-based ARM radar simulator is also applied to ACME to compare its simulated clouds with ARM data. This new tool will be applied to perform meaningful testings for the convection scheme of CLUBB and UNICON for ACME v1. In this poster, we will show the assessment of AMIP simulations with 1 degree and 30 layers model for the control runs and the candidate convection schemes. The results will provide useful information on the selection of convection parameterization for ACME v1. The Tier 1b cloud collection will be also used to the analysis of v0.3 AMIP ensemble runs ne30 and ne120 for the impact of resolution changes.
