Description
The Large-Eddy Simulation (LES) Atmospheric Radiation Measurement (ARM) Symbiotic Simulation and Observation (LASSO) project is designed to provide routine large-eddy simulations at ARM sites. The end result is LASSO data bundles containing model inputs, such as forcings, simulation configuration and output, hourly model-observation diagnostic metrics, and skill scores to assess model performance. The pilot phase of LASSO, starting with shallow convection cases over the Southern Great Plains (SGP) facility, has recently been completed. This poster presents the data flow and Value-Added Products (VAPs) of the LASSO Operationalization (LASSO-O), an ARM Translator project aimed at migrating LASSO post-simulation generation pilot code into the ARM Infrastructure framework using the ARM Data Integrator (ADI). In addition to producing model-observation data for the bundles, LASSO-O includes a full suite of quicklooks designed to compare simulations to one another and to observations. LASSO-O also offers new observational products, produced daily, such as the Lifting Condensation Level (LCL) and Cloud Fraction VAPs. For shallow cumulus cases only, other new VAPs provide (1) Doppler lidar shallow cumulus cloud base heights and (2) 10-min hybrid thermodynamic profiles generated from the AERIoe VAP, Raman lidar, and soundings. Results from and data availability of the new VAPs will be presented.
