The results of lidar sensing aerosol pollution in St. Petersburg (Russia) were compared with ones located Minsk (Belarus) and Kuopio (Finland) to assess the impact large cities on atmospheric by particles. For comparison, optical depth (AOD) data obtained at three stations from 2014 2021 used. Lidar sounding aerosols was carried out using Nd:YAG lasers operating wavelengths: 355, 532 1064 nm. Due differences station equipment characteristics and, consequently, lower limit for determining...
Measurements of vertical profile wind speed and direction at the Resource Center "Observatory ecological safety"
, St. Petersburg, Russia,
Processing of data obtained using lidar technologies was carried out to identify the vertical variability distribution aerosols in atmospheric column by month. The results 227 measurements from 2014 2023 were processed total. It has been established that concentration and height compacted aerosol layers begin increase spring time, reaches a maximum July, October there is visible decline concentrations air. warm season 1200–1800 m, while cold it only heights 600–1100 m. concluded fine...
The aspects of purification discharged ballast water from non-indigenous species microorganisms in by the management systems (BWMS) installed on ships are considered. As a method treatment, technology chosen is to influence with gaseous ozone introduced into flow when it received onto ship. A design diagram for prototype BWMS unit treating during intake and deballasting has been developed. results studies inactivation various salinities (0, 18 36‰) presented its effectiveness shown....
The results of long-term (during the 8-year period) observations aerosol optical depth in center St. Petersburg are presented, which performed using stationary lidar complex Resource Center "Observatory environmental safety", Research Park, University. It has been established that content particles over city prevails summer and spring seasons, while minimum aerosols is observed winter.
The lidar sounding in the cloudy atmosphere needs accounting multiple scattering. standard approach for retrieval of optical parameters and morphology aerosol particles might be not sufficient. Here theoretical analyti cal numerical methods calculation scattering contributions backscattered signal are used. thickness clouds that provokes a distinct multiply scattered light is determined. possible correction as subtraction part from registered proposed optically thicker than 4. routine...
The results of lidar sounding in the Resource Center "Observatory Environmental Safety" St. Petersburg University, Research Park, have been obtained center Petersburg. Observations are accomplished during 12 hours on 5 March 2015, from 11 am till pm. Four time periods considered. Results AERONET observations and retrieval at 4 stations around region considered addition. Optical models atmosphere day night constructed used for radiation calculation. radiative divergence, transmitted reflected...
The ongoing global warming process leads to surpassing rise of temperature within the so-called "heat islands" large cities.Thus, it is important investigate mechanics increase urban environment forecast and maintain standards environmental safety for population cities.This brief report presents scientific facts obtained by remote sensing methods that confirm model convective circulation air masses islands".That semi-quantitative was built on basis mathematical simulation movements over...

The solution of many problems associated with the air pollution, radiative regime earth's surface and atmosphere, global local environmental changes climate, facing humanity in early 21st century, require detailed regular information on atmospheric aerosol gaseous pollutants atmosphere. For monitoring especially effective were methods laser sounding which provide a vertical profile parameters to height 20 km In this regard, at beginning century created continental networks lidar stations....
