Abstract
Naloga zajema prostorsko obdelavo podatkov o vremenu in je osredotočena na analizo radarske slike padavin, do katere lahko prosto dostopamo na spletni strani Agencije Republike Slovenije za okolje. Razdeljena je na teoretični in analitični del. V teoretičnem ozadju je opisano delovanje meteorološkega radarja, način pridobivanja podatkov in zgodovina ter prihodnost radarskih merjenj v Sloveniji. Osrednja tema je bila radarska slika padavin. Sprva smo preučili njene tehnične lastnosti, kot so obseg in čas prikaza, pa povezavo med parametroma radarske odbojnosti (Z) in količino padavin. V analitičnem delu naloge smo s spletne strani ARSO s programom FME Desktop pridobili radarske slike padavin, jih georeferencirali, obrezali in reklasificirali. Po prenosu in obdelavi podatkov je sledilo agregiranje in izračun normiranih vrednosti seštevkov. Dobljene rezultate smo analizirali in prikazali na kartah, pri čemer smo uporabili programsko orodje QGIS. V nalogi smo preučevali prostorsko razporejenost padavin in presojali, ali lahko intenziteto padavin neposredno povežemo s količino padavin. Povezavo med parametroma smo predstavili matematično in praktično, tj. s pridobljenimi številčnimi rezultati.

Title:Collection and Processing of Radar Image of Precipitation of Slovenia : graduation thesis
Abstract:
This diploma thesis covers the spatial processing of weather data and focuses on the analysis of the radar image of precipitation, which is available on an open access website of Slovenian Environment Agency (Agencija Republike Slovenije za okolje or ARSO). The thesis is divided into two parts, theoretical and analytical. Theoretical part describes the functioning of the weather radar, the way of collecting data, and history and future of radar measuring of rainfall in Slovenia. The focus of the central topic is the radar image of precipitation, its technical characteristics, such as range and display time of the radar, and the examination of the connection between the parameters of radar reflectivity (Z) and rainfall depth. In the analytical part, FME Desktop tool is used to obtain radar images of precipitation from the website of Slovenian Environment Agency (ARSO), then the images are georeferenced, edited, and reclassified. The aggregation and calculation of normalized sums follow the data collection and processing. The results obtained are analysed and displayed on maps using the QGIS software tool. The thesis studies the spatial distribution of rainfall and discusses whether rainfall intensity can be directly linked to rainfall depth. The collected numerical results were used to present the connection between the two parameters mathematically and practically.

Keywords:radar image of precipitation, weather radar, normalised daily precipitation sums, rainfall intensity, rainfall depth
