The timestep here directly takes the parameter "dt_integration". For the first contrail, dt are usually not as long as dt_integration. I am wondering if this is something we can modify a little bit.
Start at line 1674 to 1684 in cocip_grid:
sigma_yy_t2, sigma_zz_t2, sigma_yz_t2 = contrail_properties.plume_temporal_evolution(
width_t1=width_t1,
depth_t1=depth_t1,
sigma_yz_t1=sigma_yz_t1,
dsn_dz_t1=dsn_dz_t1,
diffuse_h_t1=diffuse_h_t1,
diffuse_v_t1=diffuse_v_t1,
seg_ratio=seg_ratio_t12,
dt=params["dt_integration"],
max_depth=params["max_depth"],
)
Refer to the same usage in Cocip, dt is defined as contrail_2['time']-contrail_1['time'], which is reasonable.
A lot appreciate if anyone could provide some help.
