Radiation API Parameters
instantaneous fluxes: Clear Sky Radiation | Diffuse Radiation | Direct Radiation | Global Radiation
accumulated energy: Accumulated Energy (Direct, Diffuse, Global and Clear Sky Radiation)
Note: All radiation parameters are normalized on one square meter. The effective unit therefore is W/m2 or J/m2, respectively.
Clear Sky Radiation: Instantaneous Flux
Gives the instantaneous flux of clear sky radiation in Watts per square meter.
clear_sky_rad:W
Examples
-
Show the expected instantaneous flux of clear sky radiation for the next two days.

Diffuse Radiation: Instantaneous flux
Gives the instantaneous flux of diffuse radiation in Watts per square meter.
diffuse_rad:W
Examples
-
Show the five days forecast for diffuse radiation.

Direct Radiation: Instantaneous Flux
Gives the instantaneous flux of direct radiation in Watts per square meter.
direct_rad:W
Examples
-
Show the five-day forecast for direct radiation.

Global Radiation: Instantaneous Flux
Gives the instantaneous flux of global radiation (diffuse + direct radiation) in Watts per square meter.
global_rad:W
Examples
-
Show the five-day forecast for global radiation.
