N1 - Funding Information:
In this study we used Fujitsu PRIMERGY CX2550/CX2560 M4 computer system, of Research Institute for Information Technology, Kyushu University, and we employed LAPACK in Intel Math Kernel Library (MKL) for singular value decomposition. This study was carried out in the context of the 4th Madrid Turbulence Workshop, funded by the Coturb program of the European Research Council. We thank Dr. J. Garicano Mena (UPM) for giving us fruitful comments and suggestions on this manuscripts. The first author thanks Dr. Shingo Motoki (Osaka Univ.) for the visualization technique. This work was partially supported by JSPS Grant-in-Aid for Young Scientists Grant Number 19K14883.

N2 - We examine the reconstruction of a three-dimensional three-component (3D-3C) snapshot velocity field in a torus using a denoising method of compressed sensing. Using 30% of the total grid points, we could reconstruct the velocity with a relative error of approximately 10%.
