Texte intégralSustained and accurate greenhouse gases measurements at a global scale are required to improve the knowledge on their sources and sinks and thus increase the accuracy of climate change projections. In order to consolidate the global observation networks, spaceborne lidar systems for future earth observation missions are regarded as innovative and complementary components to the present operational measurement methods. In this context, this research work has consisted in developing a differential absorption DIAL lidar based on an optical parametric source able to emit in the 1,9–2,3 µm spectral range. The purpose was to demonstrate its ability to be implemented in long range measurements of the main greenhouse gases (CO2, H2O, CH4). Then, the laser transmitter has been integrated in a lidar architecture which was previously designed using a numerical model. Improvements and optimization of the lidar system focused on two aspects: the monitoring of the spectral purity of the emitter and the control of the detection and acquisition. Concentration measurements on the three gases have been carried out from the laboratory based on atmospheric backscattered signals from clouds and aerosol. These measurements provided a basis for the investigation of the error and bias sources. On the basis of these measurements, instrument scaling for future airborne demonstrations is discussed. Projected performances of a spaceborne instrument are also presented

Texte intégralLidar absorption spectrometry is a powerful solution for remote gas detection. For this purpose, longwave infrared between 8 and 12 µm is ideal as it covers characteristic absorption bands of many gases including chemical warfare agents and toxic industrial chemicals. However, the challenge of a pulsed narrow-spectrum broadly tunable in the 8 to 12 µm range has only be partially solved. This thesis aims to demonstrate how to make such a laser source basing on previous works. The master oscillator is a nested cavity optical parametric oscillator (NesCOPO) with an OP-GaAs crystal. It is pumped with an actively Q-switched 2 µm Tm:YAP laser which has been made wavelength tunable with a transversally chirped volume Bragg grating. Important design and simulation works are made to ensure single longitudinal mode operation of the pump laser while maintaining its repetition rate and peak power and wavelength tunability. Finally, with this laser and a wavelength measurement system using pump/signal SFG to perform measurements in the 8 to 12 µm range, we experimentally show that wavelength tunability of a NesCOPO is wider and faster through pump wavelength tunning than through NesCOPO non-linear crystal temperature tunning

Texte intégralThe collection of spatial data is carried out today by conventional methods,which usually provide the required accuracy of the output data in the projectsof diameter and diameter reconstruction, by various projects in the field ofengineering geodesy. On the other hand, the development of newtechnologies and data collection devices imposes new methods of work thatprovide an incomparably higher level of detail than conventional methods,and they often have an advantage over conventional, especially inengineering projects. In the dissertation, the model of geodetic diametermodel was presented with modern acquisition technologies that meets thequality criteria defined by the Land Regulations Rulebook and the criteria ofengineering geodesy.

Texte intégralOn a site that is multi-influenced by urban and industrial emissions, the analysis of aerosol pollution, in the vicinity of sources, requires a multi-scale knowledge of atmospheric dynamics. A measurement campaign was developed in order to study the meteorological and micro-meteorological variability and the evolution of particles, in particular, submicronic evolution, during a one-year period.Oscillations of the aerosol concentration around the regional average were identified along the Dunkirk coastline, and were attributed to the local meteorological phenomena close to the industries. Recognition and machine learning methods using measurements by an ultrasonic anemometer and vertical wind profiles by a Doppler lidar, were implemented to define the variability of relevant phenomena in air pollution events : sea breeze, fog, front and storm. A six-years database analysis has highlighted a correlation between the annual sea breeze occurrence and the annual number of anticyclonic days. Furthermore, the annual fog frequency could be connected with the annual regional concentration of aerosols. Analysis of wind covariance revealed two contrasting situations, low-level and high-level turbulent fluxes. The fog and the sea breeze, with low-level fluxes, generate a high PM₁ pollution and are in favor of a high organic oxygenated aerosols concentration (secondary aerosols). High-level fluxes situations, favoring vertical exchanges, are associated with a large variability of sulfate aerosols. The long-term observation, made it possible to highlight the development of episodes of particulate pollution during local weather phenomena, owing to the local emissions, but also by taking into account the larger-scale pollution

Texte intégralIt has become more popular to create 3D models among local governments and companies today. Now it´s possible to visualize most objects in 3D, which can give an increased understanding. The local government in Lidköping wants to be able to use their LiDAR data to visualize buildings and to combine several data layers with 3D visualizations to create useful web map services. At the present, there is no software that are able create 3D models of LiDAR data at the Local government. The local government in Lidköping is interested in testing different options for modelling in 3D. Two software packages were chosen; ArcGIS Pro and QGIS. ArcGIS Pro is a GIS software that is highly acknowledged in the market. It´s licensed and can be considered expensive. QGIS is a software that is completely free to use and uses open source code, which makes it possible to create algorithms that can then be used in the program. In this view, there will be comparison between a software that is expensive and a software that is completely free. The method used to compare the two software consists of three stages. Stage 1 is a software comparison, where the software capabilities are set against each other in different scenarios. Stage 2 is an investigation of positional accuracy where the coordinates of the 3D model's building corners are compared with coordinates measured with Total Station as reference. RMSE is used to compare positional accuracy. Stage 3 is a visualization analysis that takes place through a questionnaire answered by people who are familiar with GIS and 3D. The result of all three stages, according to the method performed, shows that ArcGIS Pro is the better software. At stage 1, ArcGIS Pro won five out of eight scenarios against QGIS, though QGIS was more time efficient than ArcGIS Pro. At stage 2, ArcGIS Pro had a RMSE value for height of 1,617, which is lower than the 1,961 RMSE value that was on QGIS. At stage 3, ArcGIS Pro had over 90% of the reply rate for most of the questions, representing that ArcGIS Pro’s images were better to visualize the different scenarios. Some comparisons were not completely even though. QGIS had better time accuracy because it did not get as much errors which needed further investigations as in ArcGIS Pro. Although ArcGIS Pro’s processes for creating 3D models were faster. The positional accuracy comparison for the building’s height shows higher accuracy between ArcGIS Pro and the Total Station’s measurements. In QGIS the 3D-modell had no roof model, which made it harder to get accurate height of the building.
