Half-width of pressure window to be examined (in decibars). |
Pressures must be in decibars for this to work. First, a subset of pressures is
created, in which the range is sap-dp
to sap+dp
. Here,
sap
=10.1325 dbar is standard sealevel atmospheric pressure. Within this
window, three measures of central tendency are calculated: the median, the mean,
and a weighted mean that has weight given by exp(-2*((p - sap) / dp)^2).
A list of four estimates: sap
, the median, the mean, and the weighted
mean.

The documentation for rsk-class
explains the structure of
rsk
objects, and also outlines the other functions dealing with them.
