Abstract: The irradiance and meteorological data of the location of installation is the chief requirement for estimating the influence of climate on the output of any solar energy convertor. The long term solar radiation datasets recorded at desired location with high temporal resolution are seldom available as the data logging require significant investment for deployment of robust measuring instruments in open environment. The accuracy of measurements is ensured by routine inspection and calibration which need expert vigilance and effort for quantification of uncertainty. The remote sensing satellites have solved this problem to a satisfactory level through constant improvements in algorithms which derive data from images taken at regular intervals in geostationary orbit. Thus, a satellite based global solar radiation database, such as PVGIS, which stands for Photovoltaic Geographical Information System, and provides an open interface for public to obtain the data free of cost, may be used to obtain typical meteorological data. A novel method for the visualization of air temperature, relative humidity, and global horizontal irradiance in TMY file is presented that can be helpful in the validation of data.
