- Increased arrays by one timeslice. Wind timeslice index=0 is now at `T_low-DT_high` - retrieval of wind now accounts for picking up one extra slice - if low res timestep `n==0`, set `T=-DT_high` wind equal to `T=0` wind - for lowres steps `n>0`, transfer last wind slice at `T=T_low_previous-DT_high` to `T=T_low_now-DT_high` - NOTE: it might also be possible to copy the `T=T_low_previous+n_high_low*DT_high` over to `T=T_low` since they are technically the same
