The Multiscale Observing System of the Ocean Surface (MOSES) is an aerial observing system that was developed jointly at UCLA and Ifremer (France). It is a relatively low-cost package that includes off-the-shelf cameras, combined with accurate Applanix IMU/GPS to provide geo-referenced observations of the ocean surface. The primary camera in the system is a FLIR A6751 SLS longwave infrared camera, providing measurements of sea surface temperature at a resolution of several meters.
