Abstract: In this work we use multi-instrumental observations to study Active Region (AR) coronal jets. Such jets are usually observed either at the base of the corona in Extreme Ultraviolet (EUV) observations, or in the outer corona in White Light (WL) coronagraph data. Even though these are observations of the same structures at different stages, there is a difficulty in recognizing the same features in the different field of views. This study attempts to bridge that gap by coupling the lower EUV and upper WL corona observations using the coronal magnetic field as the common denominator and the shape of the jets obtained from triangulation techniques. For that purpose we use observations from Solar Orbiter's Extreme Ultraviolet Imager (EUI) and Metis coronagraph. We show that such AR coronal jets are the result of reconnection between the AR's magnetic loops and the ambient open field, and we are able to connect those jets seen in Metis with their source AR observed in EUI images. Our results give a coherent picture of the coronal jet dynamics and can be used in combination with computations of the solar wind in the heliosphere.
