Thermal infrared camera module for Satellite-Based Sea surface temperature monitoring in thin cirrus clouds areas

The development of a Thermal Infrared Camera Module designed for satellite-based Sea Surface Temperature (SST) monitoring addresses the critical challenges of SST monitoring in regions with frequent thin cirrus cloud cover, such as the Banda Sea and Arafura Sea. The design process included spectral range determination; optical performance analysis using Zemax; mechanical design using CAD; thermal and structural design using Thermal Desktop-SINDA/FLUINT; and complementation consisting of electronics and calibration. The results in figures and tables show that the module meets all technical criteria. The spectral range of 9.5-11.5 mu m allows the module to penetrate clouds, providing accurate SST data in tropical regions where existing systems such as MODIS and VIIRS have difficulty. The module offers a spatial resolution of 400 m, above the resolution of MODIS and VIIRS. These advantages make the camera module an effective tool for monitoring climate change, sustainable fisheries management, and marine ecosystem health.
