NSRDB grid coordinates?
I would like to download a collection of NSRDB data files spanning across Oahu. The NSRDB API requires that I specify the latitude and longitude for each point for which I want to retrieve data. The natural way to use this would be to loop through the coordinates of the NSRDB 4-km grid over Oahu and request a data file for each point. However, after a couple of hours of searching I haven't been able to find the coordinates of the NSRDB grid cells. Is there any place where I can find information on the location / coordinates of the NSRDB grid cells?
I tried downloading annual average PSM Global Horizontal Irradiance from the NSRDB Data Viewer, but that only gave a list of values for the cells I selected -- no information on the location of the cells!
Thanks for any help you can give.
