Investigation of the Air-Wave-Sea Interaction Modes Using an Airborne Doppler Wind Lidar: Analyses of the HRDL Data Taken During DYNAMO
Abstract
The long-term goal is to analyze and, if necessary, reprocess the shipboard HRDL (High Resolution Doppler Lidar) data taken during the DYNAMO field campaign in order to make comparisons with existing airborne DWL measurements (TODWL) and to conduct investigations into the utilization of the data for studying atmospheric features and phenomenon during various conditions. One of the main objectives of our research was to see if what was learned from the TODWL (CIRPAS) and P3DWL (NRL) experience regarding rain in the field of view of Doppler Wind Lidar (DWL) data could be applied to the shipboard HRDL observations taken during DYNAMO. A second objective was to use the HRDL data and the W band radar data taken aboard the USS Revelle to investigate vertical motions within physically thick (optically thin) cirrus layers. During our evaluation of the HRDL data we have added a third objective which is to investigate dry convection rolls (Organized Large Eddies, OLE) from the perspective of a ship-borne DWL for comparison with that obtained from an airborne DWL during TODWL flights in April 2007 near Monterey, CA. This additional research objective is tightly associated with the research we are doing under another ONR DRI, the Unified Physical Parameterization for Extended Forecasts DRI, where the EDMF flux parameterization is being evaluated for its use in numerical models for seasonal predictions.
