Airborne lidar altimetry can measure the sea surface height (SSH) over scales ranging from hundreds of kilometers to a few meters. This collection has SSH observations taken during an airborne lidar campaign conducted in the spring of 2019 off the California coast in support of the Surface Water and Ocean Topography (SWOT) mission. The collection consists of NetCDF files with all data necessary to reproduce the figures in Villas Bôas et al. (2022), which were based on flights from March 28, 2019, and April 9, 2019. The data can be used in conjunction with code available in the following GitHub repository:
The production of this collection was supported by NASA award 80NSSC20K1136 through the SWOT program; NASA award 80NSSC19K1004 through the S-MODE program, and through NASA JPL contract 1618801.

The data is separated by crosswind (crosswind/) and upwind-downwind (upwind/) tracks. dirspec/ Two-dimensional surface wave spectrum computed from MASS based on sea surface height data grided on 0.5 m horizontal bins. Wave bulk parameters such as significant wave height, direction, and wavelength are also included in the files. 5- chereskin/ AltiKa sea surface height spectrum as appears in Figure 14 of Chereskin et al., 2019.
