One-minute global irradiance time series
This tool lets you upload your time series of global irradiance with one hour resolution and generates high quality time series with one minute resolution.
One-minute time series with close-to-natural variability will be synthesized based on a algorithm described here.
It is free to use, and we are glad if you use it, but please cite:

Some example datasets: Berlin, Germany | Carpentras, France
Upload the data
Just paste your data in the textbox here, without timestamps.
- The values must be in W or Wh
- Local time must be used, without daylight saving time shift
- There must be exactly 8760 values, one value per hour of one year.
- Use a point as decimal separator
- You can use a newline (\n), tab (\t), semicolon (;) or comma (,) as field separator
The values will be checked for consistency and synchronicity before synthesizing
Set the location
Select the location by clicking on the map.
Be sure to choose the right location. The algorithm needs to calculate the correct sun paths.

Synthesize
You are ready to synthesize. The full year will be synthesized and you will see 5 days as preview.
If you want to download the data, you can do so afterwards.
