Solar radiation measurements (raw)

Description

Returns an example dataset of solar irradiance monitoring from 2012-2015 at 1300 m a.s.l. in the Swiss Alps (Loetschental, Switzerland; Peters et al. 2019). Solar irradiance (W m^{-2}) was measured with 15‐min resolution using a microstation (Onset,USA, H21-002 Micro Station) and pyranometer (Onset, USA, S‐LIB‐M003) positioned in an open field.

Usage
