Airborne eddy covariance measurements of ocean-air VOC fluxes: Distinguishing signal from noise

Abstract. Ocean-atmosphere exchange plays an important but uncertain role for many volatile organic compounds (VOCs). Airborne eddy covariance (EC) enables direct flux quantification over large areas, but VOC applications have largely been performed over land. Here we combine the...

Polarization calibration of spaceborne lidar using dense cirrus–scattered solar background with molecular scattering correction

Abstract. Accurate calibration is essential for spaceborne polarization-sensitive lidars, as biases in depolarization ratio measurements can significantly affect the retrieval of cloud and aerosol properties. A polarization calibration technique based on solar background signals...

Regional FireworksPollution over East and SoutheastAsia from Airborne Observations around the Spring Festival Period

Abstract Fireworks are spectacular, but they also pollute the atmosphere. While fireworks are known to rapidly increase local pollution levels, the regional influences and nanosized appearance of fireworks-related particles are poorly understood. This study collected aerosol part...
