One issue exists with DHDT_DYN, while it includes the divergence of H, it also includes other terms from the dynamical routines, and so, does not globally integrate to ~0 as divergence should. Just be aware that we do not have the divergence H written as its own term.
Thank you for the reply. Given this information, what is the most appropriate way to calculate vertically integrated moist static energy (MSE) from MERRA-2 outputs, as there is no dry enthalpy variable? Is it appropriate to use CpTv instead, given that the correction for virtual temperature is relatively small?

Take a look at this paper, it has a complete total energy budget discussion, with equations and also variable names in the appendix. The paper is MERRA, but most of that still holds for what is included in MERRA-2.
