Airborne LIDAR technique by its specifications and characteristics in terms of precision of the numerical terrain model and the use of the GIS technique can be used in geomorphology. REELD campaign (elaboration of a precise numerical model of the terrain over the whole Romanian Danube Plain with more than 600,000 ha distributed along 1,000 km and variable widths from 1 to 80 km large were scan from 600 m altitude) represented an opportunity for the

The chemistry flight as0729 performed on the 16th of July 2007, between 14h20 and 16h20 local time was dedicated to pollution tracking above the Moldavia province in Romania. We wanted to explore two urban agglomerations: Iasi (47´09N; 27´37E) and Roman (46´55N; 26´54E) distant about 50 km from one another in straight line. Industrial zones are implanted in these areas. We went to explore the vertical distribution of the pollutants above these

This study consisted in a precise mapping project (GPS field campaign, on-screen digitization of the topographic maps at 1:5.000 scale and updated with ASTER mission) of the Ceahlãu mountain area in Romanian Carpathians in order to address the snow avalanche risk management, surveying and monitoring. Thus we considered the slope, aspect, altitude, landforms and roughness resulted from a high resolute numerical terrain model (31 square km at 1: 5.000

As a possible direct consequence of the climate perturbations the extreme events start to affect significantly the humanity at the national scale e.g. Danube floods in Romania. In this context a unique work was performed in 2007 over the whole Romanian Danube plain in order to elaborate a very high resolute numerical model of the terrain. Thus about 600.000 ha distributed along 1000 km and variable widths from 1 km to 80 km large were scan from 600m

Simulations of the hydrological risks and thus the decisions of assessment strategies are crucial in the context of extreme meteorological events due to the consequences of the fast changes in the climate. The remote sensing methods, such as LIDAR backscatter technique are allowing the elaboration of a high precision (5cm vertical and 3 points/m2 horizontal resolutions) Digital Terrain Model (DTM) as basis of the hydrological modeling. In this paper

Ozone, nitrogen oxide and sulphur dioxide point monitor measurements were taken in the periphery of the urban area of Bucharest city in April 2006. Four days (03-06.04.2006) results are here presented. The discussions are focused on the selected 24 hours measurements from 4.06 at 6h00 particularly on the ozone and nitrogen oxides interacting processes.
