BoM GASP Back Trajectories for the NSF/NCAR C130 Divergence Rates and Subsidence Velocities



Divergence rates and subsidence velocities were calculated for times during ACE-1 when the C-130 was flying cirles in the boundary layer. These were calculated by simply following the actual subsidence/ascent on numerical (GASP/HYSPLIT) trajectories. These values agree well with the synoptic meteorology.
