The air-sea flux and surfacw wave were observd in a fixed platform( 21º26.5' N, 111º23.5' E), during the measurements from 6 February to 8 May 2012, the turbulence observed by the high-frequency ultrasonic anemometer (Gill R3-50) mounted at a height of 8 m, and waves were observed by the An acoustic wave and current (AWAC) sensor (Nortek, Rud, Norway).
The data provided are:
U8: Wind speed observed from ultrasonic anemometer fixed at 8 m height above the sea surface;
Wind direction(from): Wind direction observed from ultrasonic anemometer;
Wave direction(from): wave direction from acoustic wave and current (AWAC) sensor;
Atmospheric Stability (z/L): Atmospheric Stability z/L, where z is height, and L is Obukhov length;
wave age (cp/U8): Peak wave age ;
τx/ρ: total wind stress in longitudinal direction ;
τy/ρ: total wind stress in lateral direction;
τtx/ρ: turblent wind stress in longitudinal direction ;
τty/ρ: turblent wind stress in lateral direction;
Cd(COARE): the drag coefficient computed by COARE 3.0 ;
case: It represent the cases shown in figures 6~7 in the main text.
