Airborne sea surface temperature and surface roughness images taken during the LASER drifter deployment in the Gulf of Mexico on 2016-02-11

Infrared Sea Surface Temperature (SST) images using an infrared camera and surface roughness images using visible cameras looking at the sun glint were collected using cameras on-board the Partenavia (P.68) airplane at an approximately altitude of 1000m during LASER experiment on February 11, 2016. Images were georectified using the onboard motion unit (IMU). The light intensity was high-pass filtered to remove scales larger than about 100-200m (depending on the incidence angle). The contrast of light intensity was calculated as the ratio of the high pass filtered data by the raw data. Composite maps were created using only parts of the images with specific sun and sensor angles. SST images were georectified using the onboard motion unit (IMU). The SST was not corrected from the possible drift of the instrument. Additional correction using the additional calibrated KT19 sensor was not included here. Composite maps were created using every possible image acquired during two airplane passes (19:10 - 19:20 UTC and 19:24 - 19:31 UTC). This dataset includes the flight tracks and georeferences from the IMU. Further details are published in: Rascle, N., Molemaker, J., Marié, L., Nouguier, F., Chapron, B., Lund, B., & Mouche, A.
