adpEnsembleAverage {oce} | R Documentation |
Ensemble averaging of adp
objects is often necessary to
reduce the uncertainty in velocity estimates from single
pings. Many types of ADPs can be configured to perform the
ensemble averaging during the data collection, due to memory
limitations for long deployments. In cases where the instrument is
not memory limited, it may be desirable to perform the ensemble
averaging during post-processing, thereby reducing the overall
size of the data set and decreasing the uncertainty of the
velocity estimates (by averaging out Doppler noise).
adpEnsembleAverage(x, n = 5, leftover = FALSE)
x |
an |
n |
number of pings to average together. |
leftover |
a logical value indicating how to proceed in cases
where |
A reduced object of adp-class
with ensembles averaged as specified. E.g. for an adp
object with 100 pings and n=5
the number of rows of the data arrays will be reduced by a factor of 5.
