USVI Longford Raw Data: Preset Calculations
December 13, 2012 to December 20, 2013

Calculation nameEquationCondition to computeValue during failed condition
Wind Direction Delta (58-32m)abs({Avg Wind Direction @ 58m [deg]}-{Avg Wind Direction @ 32m [deg]})10

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.
