SAMURAI analysis of dynamic and thermodynamic variables and convective frequency in 20 African easterly waves using satellite brightness temperatures

This dataset includes analysis fields of various thermodynamic and dynamical variables utilizing the Spline Analysis at Mesoscale Utilizing Radar and Aircraft Instrumentation (SAMURAI) of 20 selected cases of African easterly waves (AEWs), associated with research flights during the NASA African Monsoon Multidisciplinary Analyses (NAMMA) in 2006 and the Convective Processes Experiment - Cabo Verde (CPEX-CV) in 2022. Each SAMURAI analysis uses ERA5 at 1200 UTC as the background field and incorporates aircraft observations from the NASA DC-8 by performing a time-space correction due to the movement of the wave. Observations from dropsondes, flight level instruments, the High-Altitude Monolithic Microwave Integrated Circuit (MMIC) Sounding Radiometer (HAMSR), and the Doppler aerosol wind (DAWN) lidar were incorporated for the 2022 cases, and just dropsondes and flight level data for the 2006 cases. Each SAMURAI analysis grid is centered on a PV centroid (point that maximizes the area integ..., , # SAMURAI analysis of dynamic and thermodynamic variables and convective frequency in 20 African easterly waves using satellite brightness temperatures
