Global VIS (PSPV-RG780-TUVR) | {Global PSP Vent [W/m^2]}-{Global RG780 PSP Vent [W/m^2]}-{Global TUVR [W/m^2]} | 1 | 0 |
Direct VIS (NIP2-RG780-TUVR) | {Direct NIP #2 [W/m^2]}-{Direct RG780 NIP [W/m^2]}-{Direct TUVR [W/m^2]} | 1 | 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.
