| Abstract |
Climate data of Angola from the period of 1961 to 1974 was rescued from the Coimbra University Archives and digitized into excel spread sheets. This data resumes summary months of climate variable recordings such as Air Temperature, Humidity, Nebulosity, Precipitations and phenomenon’s associated with rain such as lightning and thunderstorms. The data gathers district and stations names and the three geographical coordinates and as well the dates of the occurrence of extremes. In this project the aim involves the compilation of the monthly spread sheets in to a database. Along with this aim emerge the need for the organization of the data in order to be used in the future. The aim of the projects covers as well the association of IDs to each stations and district and the transformation of the geographical coordinates into standardized ones. Besides this cover as well a quality control procedure which flags erroneous data. With the creation of an error checking system using the tolerance and consistency tests to spot errors. The data was imported from Excel into R. and R was chosen for being an open source software, very adaptable and actively supported by a large number of users and also ideal for statistical analyses. In R was possible to fulfil the objective stabled for this project. The database in compiled and ready to a next stage (Correction) which is out of the scope of this project. However it is necessary to notice that the process involving this database is continuous and in this project objectives are met although it is only a first step to the complete and complex task of turning available a database ready to be used. |
