Gridded Sea Level Height and geostrophic velocities computed with Multiscale Interpolation combining altimetry and drifters M. Ballarotta, C. Ubelmann, P. Veillard, P. Prandi, H. Etienne, S. Mulet, Y. Faugère, G. Dibarboure, R. Morrow, and N. Picot https://doi.org/10.24400/527896/a01-2022.009

Short summary

We present a new gridded sea surface height and current dataset produced by combining observations from nadir altimeters and drifting buoys. This product is based on a multiscale and multivariate mapping approach that offers the possibility to improve the physical content of gridded products by combining the data from various platforms and resolving a broader spectrum of ocean surface dynamic than in the current operational mapping system. A quality assessment of this new product is presented.
