Jet energy scale and resolution measurements with their associated uncertainties are reported for jets using 36–81 fb−1^{-1}−1 of proton–proton collision data with a centre-of-mass energy of s=13sqrt{s}=13s ​=13 TeV{ ext {Te}}{ ext {V}}TeV collected by the ATLAS detector at the LHC. Jets are reconstructed using two different input types: topo-clusters formed from energy deposits in calorimeter cells, as well as an algorithmic combination of charged-particle tracks with those topo-clusters, referred to as the ATLAS particle-flow reconstruction method. The anti-ktk_tkt​ jet algorithm with radius parameter R=0.4R=0.4R=0.4 is the primary jet definition used for both jet types. This result presents new jet energy scale and resolution measurements in the high pile-up conditions of late LHC Run 2 as well as a full calibration of particle-flow jets in ATLAS. Jets are initially calibrated using a sequence of simulation-based corrections.
