The jet energy calibration (JEC) measurements, based on a data sample collected in proton-proton collisions at a center-of-mass energy of 13TeV recorded by the CMS experiment at the LHC Run 2 are presented.
The calibrations are extracted from data and simulated events and employ the combination of several channels and methods.
These successively correct for contributions of pileup, and absolute scale of the jet energy scale as a function of $\eta$ and $p_{\rm{T}}$ in simulation.
To account for any residual differences with jet energy scale in data, in-situ calibrations are determined using dijet, photon+jets, $Z$+jets and multijet events. Several techniques are used to account for various sources of scale corrections and their uncertainties.
