Estimate atmospheric pressure in rsk record.
rskPatm(x, dp = 0.5)
an rsk object.
Half-width of pressure window to be examined (in decibars).
A list of four estimates:
sap, the median, the mean, and the weighted mean.
Pressures must be in decibars for this to work. First, a subset of pressures is
created, in which the range is
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 \(exp(-2*((p
- sap) / dp)^2)\).
The documentation for rsk explains the structure of
rsk objects, and also outlines the other functions dealing with them.
