  We present TURB-Rot, a new open database of 3d and 2d snapshots of turbulent
velocity fields, obtained by Direct Numerical Simulations (DNS) of the original
Navier-Stokes equations in the presence of rotation. The aim is to provide the
community interested in data-assimilation and/or computer vision with a new
testing-ground made of roughly 300K complex images and fields. TURB-Rot data
are characterized by multi-scales strongly non-Gaussian features and rough,
non-differentiable, fields over almost two decades of scales. In addition,
coming from fully resolved numerical simulations of the original partial
differential equations, they offer the possibility to apply a wide range of
approaches, from equation-free to physics-based models. TURB-Rot data are
reachable at http://smart-turb.roma2.infn.it
