| Popis: | The objective of this study was to measure the intensity of photosynthetically active radiation (PAR), ultraviolet A (UVAR) and ultraviolet B (UVBR) for one year (May to December 2013 and January to April 2014) in Florianópolis. Measurements were performed every Monday, Wednesday and Friday at 1-hour intervals from 10:00 a.m. to 2:00 p.m. The highest intensities of PAR were observed in January, followed by February, November and December. The highest intensities of UVAR occurred from September to February, and for UVBR, from November to February. Taking into account the time, the incidences of PAR showed no statistical difference, UVAR intensities were higher than those of UVBR during all months and at all times. For UVAR the incidence peaks occur at noon, while the UVBR was more constant during measured times. Seasonally, it was noted that the highest indices of PAR, UVAR and UVBR occurred in summer. |
