Sub-Mesoscale Ocean Dynamics Experiment: Surface currents and Sea Surface Temperature

Airborne observations of surface currents from Doppler Scatterometer and sea surface temperature from infrared camera.

This data set is derived from the S-MODE project  https://github.com/podaac/2022-SMODE-Open-Data-Workshop.

Description of the data:

DopplerScatt surface current spatial resolution of 200 m

MOSES SST nominal spatial resolution of 10 m, but interpolated to DopplerScatt grid at 200 m resolution.

Submesoscale_Frontogenesis = The variables included in the file are necessary to compute frontogenesis

Variables:

SST_moses = sea surface temperature

U_hp = high-pass east-west velocity component

V_hp = high-pass north-south velocity component

Tx = SST gradients in east-west direction

Ty = SST gradients in north-south direction

U_hp_(rot,div) = high-pass east-west velocity component rotational and divergent component

V_hp_(rot,div) = high-pass north-south velocity component rotational and divergent component

Fs_rot = Frontogenetic tendency due to the rotational component of the velocity field

Fs_div = Frontogenetic tendency due to the divergent component of the velocity field

Fs_tot = Frontogenetic tendency

Strain_rot = Strain deformation due to the rotational component of the velocity field smoothed at 1 km

Strain_div = Strain deformation due to the divergent component of the velocity field smoothed at 1 km

rv_lp = relative vorticity smoothed at 1 km

dv_lp = divergence smoothed at 1 km

Strain_lp = strain deformation smoothed at 1 km

Strain_normal = normal strain deformation smoothed at 1 km

Strain_shear = shear component of the strain deformation smoothed at 1 km
