Collection of temperature, salinity, ocean currents, and temperature variance dissipation (chi) profiles gridded on 1-meter pressure levels from profiling EM-APEX floats deployed in all ocean basins during the Sampling Quantitative Internal Waves Distribution (SQUID) experiment funded by the National Science Foundation as part of the Global Internal Waves project of the National Oceanographic Partnership Program (NOPP). There are 5 NetCDF files included in this package and are described in the readme.txt provided.
