Meteorological parameters

Meteonorm is more than irradiation and temperature data only. It gives you access to more than 30 different meteorological parameters for any location worldwide.

Radiation parameters

Label Parameter
BhDirect horizontal radiation arising from a narrow solid angle of 6° centered around the sun
BnDirect normal radiation (DNI, beam) arising from a narrow solid angle of 6° centered around the sun's disk
DhDiffuse radiation arising from the upper hemisphere reduced by the direct solar radiation from the sun's disk and its surroundings (6° aperture)
Dh horDiffuse radiation taking raised horizon into account
Dh minDiffuse radiation under clear skys
GhGlobal horizontal radiation ("GHI")
Gh horGlobal radiation taking raised horizon into account
GhmaxGlobal radiation under clear skys
