Meteorological Data

Previous editions of this book included an extensive meteorological database. These data were subject to change as additional measurements became available, as further refinements were made in the processing of existing data, and as the inevitable errors were uncovered and corrected. For many years obtaining reliable weather data was difficult and time consuming. In recent years data have been made instantly available on the Internet by national weather services, research laboratories, and commercial organizations. When designing a solar system the best data should always be used. Since data in a book are old when the book is published, it was decided to include only a limited data set.

The meteorological data in this appendix are used in example problems in the text, in designing typical systems by the methods presented in Part III, and for use in exercises in Appendix A. The data include the monthly average daily radiation on a horizontal surface, in the monthly average clearness index; the 24-h monthly average ambient temperature, in and , the average number ...
