We make publicly available a catalog of calibrated environmental measures for galaxies in the five 3D-HST/CANDELS deep fields. Leveraging the spectroscopic and grism redshifts from the 3D-HST survey, multi wavelength photometry from CANDELS, and wider field public data for edge corrections, we derive densities in fixed apertures to characterize the environment of galaxies brighter than $JH_{140} < 24$ mag in the redshift range $0.5Comment: 35 pages, 29 figures, 2 tables. Accepted for publication in ApJ. The catalogue of environmental measures is available at: http://dx.doi.org/10.5281/zenodo.168056
