The precise measurement of the missing transverse momentum ($p^{miss}_
{T}$) observable is critical for
standard model measurements involving W, Z, and the Higgs bosons, and top quarks. In addition,
$p^{miss}_
{T}$ is one of the most important kinematic observables used in searches for physics beyond the
T standard model targeting new weakly interacting neutral particles. A detailed understanding of
various effects due to the high collision rate at the CMS detector during the 13 TeV data-taking
period of the LHC both in data and simulation is important to achieve the most optimal $p^{miss}_
{T}$
performance. In this talk, we will present studies of $p^{miss}_
{T}$ reconstruction algorithms using the
T CMS detector at the LHC.
