Tracking Aerosol Convection Interaction Experiment (TRACER) Model Intercomparison Project (MIP)#
Background and Motivation#
The DOE ARM Tracking Aerosol Convection Interaction Experiment (TRACER) campaign took place in the Houston, TX region from 01 October 2021 through 30 September 2022, with an IOP from June-September 2022, which collected a comprehensive dataset focused on the evolution of convective clouds and their environment (including aerosol, cloud, thermodynamics, and lightning). A unique component of TRACER is that a large number of individual, isolated convective cells were tracked and measured with high spatial and temporal resolution. These comprehensive, unique observational datasets can help evaluate model and parameterization performance, identify model and parameterization deficiencies, and gain new insights to improve models. This provides the motivation for conducting an additional community model intercomparison project (MIP) based on the previous Aerosol Cloud Precipitation Climate (ACPC) Deep Convective Cloud (DCC) MIP (ACPC-MIP; van den Heever et al. 2017; Marinescu et al. 2021; Saleeby et al. 2025; van den Heever et al. 2025), which is referred to as the TRACER-MIP.

We have limited UAS data for the first case (17 June), including 18 CopterSonde and 1 RAAVEN flights. However, I’d be happy to support broader (beyond UAS) data analysis needs, as able. |
