Data for Paper: Wind-wave momentum flux in steep, strongly forced, surface gravity wave conditions

Laboratory measurements of wind, waves, and airside static pressure under low to moderate wind forcing (U10 ~ 6 -16 m/s) collected in Oct 2022 in the SUSTAIN wind-wave facility at the University of Miami.

This dataset includes 11 runs, all of which contain monochromatic waves generated by the wave paddles with various wind forcing exerted above. All data is in ".mat" formate readable via MATLAB.

Experiment set up and positions of instruments are documented in more details in the manuscript Tan et al (2024): Wind-wave momentum flux in steep, strongly forced, surface gravity wave conditions.

 Fig_3: time series static pressure p sampled at 100 Hz and horizontal/vertical wind speed (u/w)  sampled at 1000 Hz

Fig_4: Frictional velocity u_star_Rn* obtained at differenet heights (h) using frictional velocity

Fig_5: a folder that containes the phase-averaged, spline-interpolated static pressure (p2_total), X-coordinate (long-wave phase), Y coordinate (heights above the stationary water) and the u/w at respective heights to generate airflow streamlines

Fig_6 and 7: NSS-based phase-averaged, spline-interpolated pressure (delta_P_new).

Fig_8: phase-averaged form stress based on measurements and NSS for all 11 runs

Fig_9: NSS-based form stress deviation from measured form stress (NSS miscal) against wind-steepness and wave age;

Fig_10 and 11: wave growth rate (gamma) against wave age (Cp/ustar) and two other parameterization from Fig.10

(The revised version contains the projection of Donelan (1999) and Yang et al. (2013)'s data to the U10/Cp parameterization in panel (b) per reviewer's suggestion);

Fig_12: form stress values (tau_form) and form stress to total stress (tau_tot) ratio.

(The revised version contains U10 per reviewer's suggesion).
