The WOS facility offers access to services for provision of comprehensive information and studies necessary for the description of the urban boundary layer. It includes both multifaced analysis of measurements taken (Doppler lidar, Near-Range Raman Lidar, Aerosol Depolarization Lidar, Microwave radiometer, weather station, Pollen sampler, Aethalometer, and Nephelometer) and small-scale meteorological and air-quality modeling (PALM). Additionally, we offer the use of in-house developed tools for retrieval of boundary layer properties based on the synergy of instruments (LIRAMI). Our approach allows for adjusting measurements and the codes to the needs of the user. For the boundary layer studies the WOS facility offers an access to Remote Sensing Laboratory  and Radiation Transfer Laboratory. The user can get access to both of them, depending on the needs. WOS facility location in a flatland urban environment, in close vicinity to the strict city center of Warsaw makes the observatory a perfect location for investigating urban boundary layer behavior and dynamics during different seasons. It also enables the possibility of assessing the urban heat island effect, as well as study of diurnal patterns of air pollution concentration including its vertical transport or fog/smog conditions. In Warsaw, there are available stations of state air quality monitoring agency – CIEP that can be considered representative for WOS facility surroundings and vice versa. Thus services to AQMN can be also targeted.

TIME CONSTRAINTS: The remote and physical access of the external users at the WOS facility must be discussed and planned with the PI of WOS and the TNA coordinators. 

External users are allowed to access WOS observatory only under WOS personnel supervision, prior to their registration in the Visitor System.

The user must go via HPS training prior to accessing the WOS facility.

SERVICE STATUS: The service is available (operational and ready to be offered). Among others, the following instruments are available at WOS: stationary multi-wavelength near- and far-field Raman lidar with polarization and water vapor capability, mobile multiwavelength Raman lidar with fluorescence capability, stationary photometer, Doppler lidar, microwave radiometer, disdrometer, shadowgraph, gas spectrometers, pollen monitor, different microscopes, aethalometer, ambient nephelometer, nephelometer with humidity chamber, compact cloud chamber, aerodynamic tunnel, integrating half-sphere FTIR, wide range of radiation sensors, set of meteorological sensors, radio-sounding system  

The service is related to access to WOS facilities for dedicated experiments tailored to the needs of users, with the possibility of use of the instrumentation existing onsite and/or provided by the user. The service offers assistance and expertise to the WOS researchers at the stage of planning campaign details, taking measurements, data collection, and evaluation. Experienced scientists employed at the WOS are experts in various fields thus able to provide the analyses, expertise, and skills in the area of atmospheric aerosol properties, lidar measurements, aerosol microphysics retrieval from the lidar profiles, radiative transfer, and cloud and turbulence modeling. Users of the WOS facility can get access to the internal algorithms developed on-site, among others the LIRAMI, LILI, EMERALD and PROfiler, to enhance their analysis. WOS facility comprises 3 labs: Remote Sensing Laboratory, Radiation Transfer Laboratory, and Fluid Dynamics Laboratory. The user can get access to all of them, depending on the needs. From the technical point of view, the service offers support with the measurement device installation as well as advice on the issue of transportation of measuring equipment. The WOS facility has dedicated laboratories for atmospheric physics measurements and measuring instrument calibration with a good connection (stairs / sliding roof-window) to the observational platform on the roof of the building. WOS facility geographic position, in East-Central Europe in a flatland urban environment makes the observatory a perfect location for investigating different aerosol types, atmospheric processes, and setting up experiments with the support of the researchers and technicians operating WOS.
