Abstract
A study of comparison of water vapor mixing ratio profiles, relative humidity profiles, and cloud vertical structures using two different instruments, a multiwavelength Aerosol-Depolarization-Raman lidar and radiosoundings, is presented. The observations were taken by the lidar located in Warsaw center and the radiosoundings located about 30km to the North in Legionowo (Poland). We compared the ground-based remote sensing technology with in-situ method in order to improve knowledge about water content thought the atmosphere and cloud formation. The method used for retrieving the cloud vertical structure can be improved comparing the radiosonde results with the lidar observations, which show promising results.
Highlights
Clouds are key factor that rule climate
The water vapor mixing ratio (WVMR), the relative humidity (RH) and the cloud vertical structure (CVS) in the atmosphere are important characteristics for describing the impact that clouds have in the atmosphere
The idea is to see if the results obtained with Active Remote Sensing of Clouds (ARSCL) data product are comparable with those obtained with measurements taken by a multiwavelength Aerosol-Depolarization-Raman (ADR) lidar
Summary
Clouds are key factor that rule climate. Improving methods for automatic and continuous description of clouds has a huge importance in order to determine the role of clouds in climate and their contribution to climate change [1]. There is ongoing work being done to improve these methods and compare them with the most advanced groundbased remote-sensing technologies, such as the Atmospheric Radiation Measurement (ARM) Program value added product, the Active Remote Sensing of Clouds (ARSCL), as well as with satellite data [4]. The present study aim is to make similar comparisons between radiosounding methods and advanced multiwavelength lidar measurements in Poland. The idea is to see if the results obtained with ARSCL data product (which is a combination of measurements taken with cloud radar, micro-pulse lidar, and ceilometer) are comparable with those obtained with measurements taken by a multiwavelength Aerosol-Depolarization-Raman (ADR) lidar. Apart from CVS comparison, the WVMR and RH profiles retrieved from the RS are compared, since the multiwavelength lidar provide profiles in Raman channel for water
