Abstract

Because of the existence of blind zone and transition zone, the application of backscattering lidar in near-ground is limited. The side-scatter lidar equipped with the Charge Coupled Devices (CCD) can separate the transmitting and receiving devices to avoid the impact of the geometric factors which is exited in the backscattering lidar and, detect the more precise near-ground aerosol signals continuously. Theories of CCD side-scatter lidar and the design of control system are introduced. The visible control of laser and CCD and automatic data processing method of the side-scatter lidar are developed by using the software of Visual C #. The results which are compared with the calibration of the atmospheric aerosol lidar data show that signals from the CCD side- scatter lidar are convincible.

Abstract

The first 18 months of data from the FY-3A Total Ozone Unit (FY-3A/TOU) was collected to analyse instrument performance. Retrieval tests were carried out using post-launch calibration coefficients. Validation was analysed at 74 ground-based stations of total ozone network by inter-comparison with AURA/Ozone Monitoring Instrument (OMI) Total Ozone Mapping Spectrometer (TOMS) V8 data and comparison with ground-based measurements. The validation results show that the TOU total column ozone has an average root mean square (rms) error of less than 3.1% compared with OMI products, and less than 4.4% compared with ground-based measurements. The solar irradiance is measured continuously, and the post-launch calibration coefficients will be updated only if the change of instrument sensitivity has noticeable influence on the retrieval. The instrument is currently stable. [ABSTRACT FROM PUBLISHER]
