Seaglider data


Level 2

Variables measured by the glider, including temperature, salinity, pressure, and time of the observations. Data are gridded on a regular depth grid and separated by profiles. Value is NaN if no observation is present in that depth bin. The number of individual observations in each bin is recorded. 

Seaglider has a good flight model, which uses the vehicle engineering variables as well as the water column observations (in-situ density) to calculate the vehicle motion through the water. Our best guess of the vehicle position is included here. 


Level 3

Interpolated version of Level 2 data, with the additional step of "despiking", where we remove outliers that are more than 3 standard deviations (T_rms_ref and S_rms_ref) for a running mean (T_ref and S_ref). 

Flags:
0 no data (interpolated), 0.5 outside despiker, 1 is good
