Improved jet energy scale corrections, based on a data sample corresponding to an integrated luminosity of 19.7 fb$$^{-1}$$ collected by the CMS experiment in proton-proton collisions at a center-of-mass energy of 8 TeV, are presented. The corrections as a function of pseudorapidity $$\eta$$ and transverse momentum $$p_{\mathrm{T}}$$ are extracted from data and simulated events combining several channels and methods. They account successively for the effects of pileup, uniformity of the detector response, and residual data-simulation jet energy scale differences. Further corrections, depending on the jet flavor and distance parameter (jet size) $$R$$, are also presented. The jet energy resolution is measured in data and simulated events and is studied as a function of pileup, jet size, and jet flavor. Typical jet energy resolutions at the central rapidities are 15-20% at 30 GeV, about 10% at 100 GeV, and 5% at 1 TeV. The studies exploit events with dijet topology, as well as photon+jet, Z+jet and multijet events. Several new techniques are used to account for the various sources of jet energy scale corrections, and a full set of uncertainties, and their correlations, are provided.The final uncertainties on the jet energy scale are below 3% across the phase space considered by most analyses ($$p_{\mathrm{T}}> $$ 30 GeV and $$| \eta| < $$ 5.0). In the barrel region ($$| \eta| < $$ 1.3) an uncertainty below 1% for $$p_{\mathrm{T}}> $$ 30 GeV is reached, when excluding the jet flavor uncertainties, which are provided separately for different jet flavors. Finally, a new benchmark for jet energy scale determination at hadron colliders is achieved with 0.32% uncertainty for jets with $$p_{\mathrm{T}}$$ of the order of 165-330 GeV, and $$| \eta| < $$ 0.8.
