APPENDIX 7

Meteorological Data

This appendix lists the meteorological data of various locations. Since this kind of information can be obtained over the Internet, data for only a few selected locations are presented, mostly used in examples and problems of the book. The data presented for the U.S. locations are from http://rredc.nrel.gov/solar, except the monthly average clearness index, which is calculated from Eq. (2.82), and the estimation of extraterrestrial horizontal radiation, given by Eq. (2.79) for the average day of Table 2.1. For the other locations, the NASA Internet site, http://eosweb.larc.nasa.gov/cgi-bin/sse, can be used by entering the longitude and latitude of each location found from www.infoplease.com/atlas/latitude-longitude.html ...
