Estimate Atmospheric Pressure in an rsk Object
Description
Estimate atmospheric pressure in an rsk object. 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).
Usage
rskPatm(x, dp = 0.5)
Arguments
x |
an rsk object. |
dp |
Half-width of pressure window to be examined (in decibars). |
Value
A list of four estimates: sap, the median, the mean, and the weighted mean.
