Short summary
Short summary
Radio and radar systems depend heavily on atmospheric refractivity. Traditional measurement tools like weather balloons are costly and limited. To solve this, we developed a Raman lidar system that remotely measures air temperature, relative humidity, and atmospheric refractivity by analyzing how light interacts with air molecules. Tests against a weather tower proved this system is highly accurate. This system provides real-time data to significantly improve radar and communication networks.

Short summary
Ocean-atmosphere temperature and humidity profiles are vital for forecasting and monitoring, yet buoys yield sparse, wave-distorted data. We replace historical fitting with a multi-objective genetic algorithm coupled to real-time platform-attitude correction, removing sway errors and enabling continuous marine atmospheric sensing.
