| Calculation name | Equation | Condition to compute | Value during failed condition |
|---|---|---|---|
| Albedo | {Reflected PSP [W/m^2]}/{Global PSP [W/m^2]} | (({Reflected PSP [W/m^2]}>0)&&({Global PSP [W/m^2]}>5)) | 0 |
| Global (RG780/PSP) | {Global RG780 PSP [W/m^2]}/{Global PSP [W/m^2]} | (({Global RG780 PSP [W/m^2]}>0)&&({Global PSP [W/m^2]}>5)) | 0 |
| Direct (RH780/NIP) | {Direct RG780 NIP [W/m^2]}/{Direct NIP [W/m^2]} | (({Direct RG780 NIP [W/m^2]}>0)&&({Direct NIP [W/m^2]}>5)) | 0 |
| Global (UV/PSP) | {Global UV [W/m^2]}/{Global PSP [W/m^2]} | (({Global UV [W/m^2]}>0)&&({Global PSP [W/m^2]}>5)) | 0 |
| Direct (UV/NIP) | {Direct UV [W/m^2]}/{Direct NIP [W/m^2]} | (({Reflected PSP [W/m^2]}>0)&&({Direct NIP [W/m^2]}>5)) | 0 |
Preset calculations are performed on the fly, as requested by user.
Calculation is only performed when condition equation is true, otherwise the failed condition value is output
Plots using a Langley calculation will be plotted versus airmass (instead of time) and will also include a linear fit with slope & intercept.
Wind Direction Deltas are special cases that go beyond the equations listed above to keep the data in the 0 to 180 degree realm.
