Revision history [back]

I first worked with satellite-derived solar on a project to update California's standard weather files used for Title-24. This solar data was obtained from a commercial source, providing 0.2 degree (lat/lon not temperature!) resolution for the entire state from 1998 through 2009. Processing the weather station data from the ISD required most of the work, importing the satellite solar was quite easy.

I've also used satellite-derived solar from NREL to calibrate modeled solar on a set of 56 Indian weather files done for ISHRAE. Direct incorporation was not feasible because at that time NREL released only 5 years of data, which has now been increased to 14 years.

For the past 3 years, WBT has been archiving satellite-derived solar from various public or semi-public sources. Starting in 2018, WBT will be offering historical weather files with satellite-derived solar radiation for the following places and time periods: Europe, Africa, Middle East to 66° east, and South America to 66° west longitude (2004 to date), Australia (1999 to date), and East Asia (2007 to date, access pending), North, Central, and South America from 60° north to 20° south latitude (1998-2015), South Asia (2000-2014).

For locations where the satellite-derived solar data are now actively updated, the past data could still be used to calibrate existing models. Another benefit to the satellite-derived solar is to make usable weather data from stations that lack cloud cover data needed by the solar models. For example, the number of usable 2017 weather stations in the UK increases from 64 to 190, and for South Africa from 37 to 184. In total, the number of 2017 weather files that WBT can produce will increase from 8,230 to 11,016 (2266 USA, 748 Canada, and 8002 International).
