Lake SkyWater-A Portable Buoy for Measuring Water-Leaving Radiance in Lakes Under Optimal Geometric Conditions.

ABSTRACT: This study introduces Lake SkyWater (LSW), a novel radiometric buoy designed for the reliable measurement of remote sensing reflectance (R_rs) in lakes using the Skylight-Blocked Approach (SBA). LSW addresses key challenges in "on-water" field radiometry owing to its motorised rotating system, which maintains the radiance sensor in optimal geometrical conditions (i.e., facing the sun). Our device is easy to transport and deploy and can be controlled with a smartphone over Wi-Fi. Its modular design, which uses standard components and custom 3D-printed parts, facilitates customisation. A field experiment demonstrated excellent performance in the visible spectrum (400-700 nm) and no significant differences compared with handheld SBA measurements when measuring R_rs (coeffi
