Abstract

IRF's Antarctica radar MARA is able to observe the atmosphere above 500m distance from ground. Hence, the radar is not only able to detect features of the free troposphere but also of the upper planetary boundary layer (PBL). Due to the inability to measure below 500m it is impossible to directly infer the coppling between surface and upper PBL. However, it is well known that surface heating is the main driving source of PBL dynamics. The heating itself depends on both surface albedo and weather conditions (e.g. cloud cover). Modeling with the the weather research and forecasting system (WRF) will help to better understand the connection by simulating dynamics during certain times of observations. WRF additionally allows to perform benchmark studies for various idealized conditions.
