Scope Dataset Data are nominally 50-min averages. Measurement height is 12 m. Data columns are as follows: Date day Month GMT decimal hour u wind speed m/s Tw water temperature Cent Ta air temperature Cent Tw-Ta Time Decimal day, september qs water humidity g/kg q air humidity g/kg del q qs-qa Hsc Covariance sensible heat W/m^2 Hsb Bulk sensible heat W/m^2 Hsi Inertial sensible heat W/m^2 Average sensible heat Hlc Covariance latent heat W/m^2 Hlb Bulk latent heat W/m^2 Hli Inertial latent heat W/m^2 Average latent heat Tuc Covariance stress N/m^2 Tub Bulk stress N/m^2 Tui Inertial stress N/m^2 Average stress U* friction velocity m/s Oph quality number for humidity; good if less than 15 and greater than 0 Tilt flow tilt in deg Zi Inversion height m -z/L Dimensionless monin obukhov similarity parameter W* Deardorff convective velocity scale tj UT same as Time Gmin min value of rms waveheight during period cm Gmax max value of rms waveheight during period cm fmin min value of dominant wave frequency during period Hz fmax max value of dominant wave frequency during period Hz average of min and max average of min and max Co wave phase speed for m/s Co/U* wave age with u* Co/Ua wave age with U H1/3 Significant wave height (4*rms) m dir True wind direction deg
