But certainly other factors which have major effects on solar radiation such as cloud cover and light dispersal do change over time, if you're trying to produce a systematic model you may want to also think about those. | |
| May 26, 2011 at 15:05 | comment | added | user3063 | Thanks for your helps. Another one think I'd like to ask is: actually I need solar radiation data for the last 8-10 years for my temporal anaysis. Is it possible I can get these information from DEM. Is there DEM data 'during 10 years'? I downloaded GTOPO30, SRTM 30m, 90m. But these DEM data were acquired within just one year. | |

| May 22, 2011 at 21:10 | comment | added | user3063 | Sorry I'm confused with the resolution of GTOP030. My area of interest is whole territory of Mongolia. it is a quite big area (1,566 sq km). Can I use SRTM elevation data at the resolution of 90 m. | |
