CHARACTERIZATION OF THE DAILY EVOLUTIONS OF GLOBAL SOLAR RADIATION AND TEMPERATURE IN SIX CLIMATIC AREAS OF THE MADEIRA ARCHIPELAGO (PORTUGAL)
The aim of the paper is to characterize the daily evolution of horizontal global solar radiation and temperature in six climatic areas of the Madeira archipelago, from the daily data recorded in six corresponding meteorological stations. An average characteristic day is obtained for each month of the year in the four-year data period 2002-2005. In relation to solar radiation, a characteristic day is defined as the day of the month with the Sun trajectory closest to the daily average Sun trajectory of the month and the daily global horizontal solar irradiation equal to the daily average of the month. It is assumed a sine-type evolution of the global irradiances along the day. In relation to temperature, a characteristic day is also assumed to have a sine-type evolution along the daylight hours of the day, with the minimum and maximum values at sunrise and two hours after noon, respectively. The characteristic minimum and maximum values are obtained averaging the daily minimum and maximum values of the month, respectively.
