  The joint analysis of different cosmological probes, such as galaxy
clustering and weak lensing, can potentially yield invaluable insights into the
nature of the primordial Universe, dark energy and dark matter. However, the
development of high-fidelity theoretical models that cover a wide range of
scales and redshifts is a necessary stepping-stone. Here, we present public
high-resolution weak lensing maps on the light cone, generated using the
$N$-body simulation suite AbacusSummit in the Born approximation, and
accompanying weak lensing mock catalogues, tuned via fits to the Early Data
Release small-scale clustering measurements of the Dark Energy Spectroscopic
Instrument (DESI). Available in this release are maps of the cosmic shear,
deflection angle and convergence fields at source redshifts ranging from $z =
0.15$ to 2.45 with $\Delta z = 0.05$ as well as CMB convergence maps ($z
\approx 1090$) for each of the 25 ${\tt base}$-resolution simulations ($L_{\rm
box} = 2000\,h^{-1}{\rm Mpc}$, $N_{\rm part} = 6912^3$) as well as for the two
${\tt huge}$ simulations ($L_{\rm box} = 7500\,h^{-1}{\rm Mpc}$, $N_{\rm part}
= 8640^3$) at the fiducial AbacusSummit cosmology ($Planck$ 2018). The pixel
resolution of each map is 0.21 arcmin, corresponding to a HEALPiX $N_{\rm
side}$ of 16384. The sky coverage of the ${\tt base}$ simulations is an octant
until $z \approx 0.8$ (decreasing to about 1800 deg$^2$ at $z \approx 2.4$),
whereas the ${\tt huge}$ simulations offer full-sky coverage until $z \approx
2.2$. Mock lensing source catalogues are sampled matching the ensemble
properties of the Kilo-Degree Survey, Dark Energy Survey, and Hyper-Suprime Cam
weak lensing datasets. The produced mock catalogues are validated against
theoretical predictions for various clustering and lensing statistics such as
galaxy clustering multipoles, galaxy-shear and shear-shear, showing excellent
agreement.
