Flatirons M2 Raw Data: Preset Calculations
August 24, 2001 to May 27, 2015
Calculation name | Equation | Condition to compute | Value during failed condition |
---|---|---|---|
Wind Direction Delta (2-5m) | abs({Avg Wind Direction @ 2m [deg]}-{Avg Wind Direction @ 5m [deg]}) | 1 | 0 |
Wind Direction Delta (5-10m) | abs({Avg Wind Direction @ 5m [deg]}-{Avg Wind Direction @ 10m [deg]}) | 1 | 0 |
Wind Direction Delta (10-20m) | abs({Avg Wind Direction @ 10m [deg]}-{Avg Wind Direction @ 20m [deg]}) | 1 | 0 |
Wind Direction Delta (20-50m) | abs({Avg Wind Direction @ 20m [deg]}-{Avg Wind Direction @ 50m [deg]}) | 1 | 0 |
Wind Direction Delta (50-80m) | abs({Avg Wind Direction @ 50m [deg]}-{Avg Wind Direction @ 80m [deg]}) | 1 | 0 |
Wind Direction Delta (2-80m) | abs({Avg Wind Direction @ 2m [deg]}-{Avg Wind Direction @ 80m [deg]}) | 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.
