Last change on this file since 4280 was 4280, checked in by monakurppa, 6 years ago

Correct recent bugs in salsa_mod and remove chemistry specific stuff in netcdf_data_iput_mod

A boundary conditions bug in salsa_mod: set top boundary to its default value (neumann) if nesting is turned off
In salsa_nesting_offl_bc, correct fac_dt to apply time_utc_init
Remove chemistry specific parts (inside an if clause id==id_emis) in get_variable_4d_to_3d_real and get_variable_5d_to_4d_real
