Construction of a new solar radiation profile and air temperature from known weather patterns for the city of Belém-PA

Abstract

In this research, five different databases are manipulated to obtain a new climate profile based on a statistical analysis of the average, minimum, maximum and standard deviation of the variables of solar radiation and air temperature for the city of Belém-PA. There is a cataloging period for each climate file, in TMY (2007-2021) there are fourteen years of data collection, SWERA (1973-1997) twenty-four years, IWEC (1982-1995) thirteen years, TRY (1964) one year and INMET (2010) one year. The variability of sample collection allowed a more accurate simulation of the mean values of the studied variables. The provision of climatological data in the collection of files used requires statistical treatment in order to enable its use in research and simulations in the area of thermal performance and energy efficiency. In this area, one of the difficulties faced by the researchers is the choice of the climate file, thus, the analysis of different sources of collection was carried out and a new set of data was extracted. The behavior of dry bulb and wet bulb temperatures and direct and diffuse solar radiation rates for each climate file was simulated using the OpenStudio software, in order to use centrality and dispersion measures as parameters in obtaining and statistically validating the new profile.
