The content of the directories are described below:

1- AVISO/
Gridded AVISO sea level anomaly in the California Current region for March 28, 2019 (aviso_20190328.nc) and April 9, 2019 (aviso_20190409.nc)

2- CDIP/
Wave buoy data from The Coastal Data Information Program (CDIP). File names follow the convention CDIP(buoy ID)_YYYYMMDD.nc

3- ERA5/
Gridded ERA 5 10 m wind velocities in the California Current region for March 28, 2019 (ERA5_20190328.nc) and April 9, 2019 (ERA5_20190409.nc)

4- MASS/
Airborne measurements from Scripps' Modular Aerial Sensing System (MASS) for two flight dates: March 28, 2019 (20190328) and April 9, 2019 (20190409)

    binned_point_cloud/
    Along-track averaged sea surface height measurements from MASS computed after binning the lidar point clound into 1 m bins. 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.
