Here we augment the existing measurement capabilities of the NOAA P-3 aircraft platform that is used for in-situ and remote sensing observations of the atmosphere. We deployed high-resolution infrared (IR) imaging of the ocean surface temperature to simultaneously identify the mechanisms responsible for the upper-ocean response and water mass modification within the MJO region. Airborne IR imagery will provide high spatial resolution calibrated SST variability. The image scale is roughly 500 m to 1000 m (depending on altitude) with resolution of order 1 m. The system allows us to characterize SST signatures including upper-ocean convection, freshwater lenses due to rain, Langmuir circulation, internal waves, and ramping of near-surface stratification at scales of O(1m-1000m). These measurements will elucidate a variety of mechanisms related to atmospheric and sub-surface phenomena that produce horizontal variability in SST over a wide range of scales under MJO forcing. This study will investigate the mesoscale, sub-mesoscale, and small-scale variability.
