calc.k.reuer | R Documentation |
This function calculates the temporal length scale of the NCP measurement, aka a piston velocity (m/d). Essentially it calculates the ventilation based on water column and wind speed over a sequence of wind speed measurements (at 10 m height).
calc.k.reuer(time, wtime, wspeed, mld, SST, teeter.mod = TRUE, verbose = T)
time |
the time at which you are calculating k for |
wtime |
a vector of times at which a wind speed is recorded |
wspeed |
a vector of prior windspeeds ordered from most recent to oldest |
mld |
mixed layer depth in meters |
SST |
mixed layer temperature in C |
teeter.mod |
a boolean flag to turn on or off the modified version of Reuer's weighting scheme as outlined in Teeter et al. 2018. |
It will return a list with the individual weights and weighted sum (for dianostics), the k value (that you want, m/d), the instantaneous k (also useful, m/d), k.hist showing the history of k values (diagnostic), and time is time before measurement that each diagnostic is referenced against (for diagnostics, d).
