Ivanov, A. Blagoev, B. Kaprielov, V. Grigorieva, V. Danchovski, I. Kolev — Atmospheric boundary layer and surface ozone concentration study over Sofia area by lidar and ozonemeter. The ecological problems caused by the increasing ozone concentration are not easy to be solved because ozone is not directly emitted by certain sources but its concentration is defined by numerous dynamical and chemical processes.
The purpose of this research is the studying of the surface ozone concentration behavior during the period of the destruction of stable boundary layer and residual layer and the formation of convective boundary layer, so as the influence of the temperature, the relative humidity and the height of the mixing layer as well as that of the formation of mixing layer in different areas of Sofia, Bulgaria to be determined.
The surface ozone concentration in the area of the Institute of Electronics changes synchronously with the development of the mixing layer. The maximum values of the surface ozone concentration are being reached when the height of the mixing layer reached its maximum and afterwards. The maximum growth of the surface ozone concentration is around h local standard time when a fast growth of the mixing layer begins and the complete destruction of the residual layer is observed, i.
The values of the surface ozone concentration during summer months are higher than those during fall. Deleva — Lidar monitoring of Saharan dust transport over the city of Sofia in the period Desert dust aerosols are the most abundant and massive type aerosol particles that are present in the atmosphere. One environmental consequence of atmospheric dust loadings is their significance for climate through a range of possible influences and mechanisms.
In this work results from three years long lidar monitoring of Saharan dust transportation over the city of Sofia are presented. Remote atmospheric investigations are carried out at the second Nd:YAG laser wavelength in the period Vertical profiles of the aerosol backscatter coefficient are processed and analyzed. The mass temporal evolution and the spatial distribution of the registered desert dust layers are illustrated by 2D-colormaps in height-time coordinates.
The observations described here are in good agreement with the forecasts of Barcelona Supercomputing Centre, concerning Saharan dust transport to Europe. Deleva, A. Slesar, S. Denisov — Investigations of the aerosol fields and clouds in the troposphere with Raman-aerosol lidar Abstract. In this work we present experimental results from regular laser remote investigations of tropospheric aerosols and clouds.
Computed vertical profiles of the aerosol backscattered coefficient are included and analyzed. The temporal evolution and the spatial distribution of the observed atmospheric layers are visualized by 2Dcolormaps in height-time coordinates.
The measurements were performed by a new three-channel lidar developed in the Laser Radar Lab, Institute of Electronics. The backscattering radiation from the atmosphere is collected by means of a big Cassegrain-type telescope 35 cm diameter, cm focal length. The wavelength spectral separator consists of two aerosol channels and one Ramanchannel. A simple, fast, and efficient receiving system is based on newly developed high sensitivity photo-receiving modules with very compact design and reliable operation.
The acquisition system is provided with specialized software, well adapted to different lidar tasks, allowing for performing comfortable detection, conversion, and processing of lidar data. The good parameters of all the laser, telescope, photoreceiving modules and software make it possible for the developed lidar to be utilized for carrying out fast and accurate long-range remote atmospheric Album) with high spatial and temporal resolution.

Gromkova, I. Butchvarov — Applying the model for transformation of the annual climatic wind rose in the air pollution modeling from point source Abstract. The necessity to transform the standard for Bulgaria climatic 8-point wind roses, named Observed Wind Roses here OWRappears in connection with the determination of the climatic annual mean air pollution concentration field from a point source, that is the purpose of most Environmental Impact Assessments.
Using an 8-point wind rose for calculating the pollution by existing applied models — a Gaussian plume model for a continuous point source, Album), the concentration isopleths follow the 8 compass directions of the wind rose and it seems that between them there is no pollution.
Using monthly means for the periodthe ERA pseudoclimatological heat and LP fluxes have been assessed for the Adriatic Sea basin and have been compared with climatological data sets.
It is shown that the shortwave and latent heat fluxes of the ERA are underestimated compared to the climatological ones. This results in overestimation of the annually averaged total heat fluxes. The ERA precipitation and evaporation are underestimated, also. The analysis shows that the ERA heat and water fluxes can not be used in their original form to force a general circulation model for the Adriatic Sea.
A simple correction procedure is applied in order to compensate the deviation of the ERA surface fluxes from the climatological ones. Rachev, R. Purini — Numerical simulations of the Adriatic sea autumn circulation.
This study presents the results of numerical simulations of the climatological Adriatic Sea circulation during the autumn. The LP of the model circulation to the different mechanical forcing is studied. LP main Adriatic Sea circulation features are simulated properly. It is shown that during the autumn the wind forcing is of crucial importance only for the formation of the northern Adriatic circulation, whereas the thermohaline circulation is found to be more important over the rest of the basin.
Numerical experiments show that the model is able to simulate well the outflow current through Otranto channel. Key words: Adriatic Sea, general circulation ocean model. Stoyanov, M. It is performed an analysis focusing on the detection, estimation, separation and elimination of site offsets of permanent GPS-tracking station SOFI excited by atmospheric loading mainly. The removing of these signals is being suggested to be done by inclusion of model predictions on the observation level in the analysis of GPS-observation or by correction of the time series after the analysis.
The estimated degree-one deformations are being proposed for reduction of geometrically defined frames and time series to inertial origin. Botev, R. Glavcheva, B. Babachkova, S. Velichkova, I. Tzoncheva, K.
