Aerosol particles and Na vapor in the antarctic middle atmosphere. Lidar measurement.

Lidar and Atmospheric Aerosol Particles

Raman lidar system for the measurement of water vapor and aerosols in the Earth's atmosphere.

A nighttime operating Raman lidar system that is designed for the measurement of high vertical and temporal resolution profiles of the water vapor mixing ratio and the aerosol backscattering ratio is described. The theory of the measurements is presented. Particular attention is given to operational problems that have been solved during the development of the system. Data are presented from Sep...

Long-Term Measurement for Low-Tropospheric Water Vapor and Aerosol by Raman Lidar in Wuhan

A Raman Lidar (RL) system is developed to measure the water vapor mixing ratio (WVMR) and aerosol optical property in Wuhan with high temporal-spatial resolution during rainless nights. The principle of the self-developed lidar system and data processing method are discussed. WVMR profiles of a representative case retrieved by RL, Radiosonde (RS), and microwave radiometer (MR) are in good agree...

Formation of highly oxygenated organic aerosol in the atmosphere: Insights from the Finokalia Aerosol Measurement Experiments

[1] Aged organic aerosol (OA) was measured at a remote coastal site on the island of Crete, Greece during the Finokalia Aerosol Measurement Experiments (FAME‐08 and FAME‐ 09), which were part of the EUCAARI intensive campaigns. Quadrupole aerosol mass spectrometers (Q‐AMSs) were employed to measure the size‐resolved chemical composition of non‐refractory submicron aerosol (NR‐PM 1), and to esti...

Semidiurnal and Diurnal Tidal Effects in the Middle Atmosphere as Seen by Rayleigh Lidar

The Rayleigh lidar at the Centre d'Essais des Landes has been adjusted to provide continuous day and nighttime measurements when clear weather permits with high resolution in both time and space. These measurements are processed to show tidal effects in the 30to 80-km height range. The observed temperature variations in two 11-day series of data, from November 1988 and January 1989, are treated...
