reducePressure R Documentation
Reduce pressure level
Description
Internal function with formula for presssure reduction
Usage
reducePressure(p, t, zgs, direction)
Arguments
p
A 2D matrix of (sea-level/surface) pressure values (in Pascals)
t
A 2D matrix of near-surface temperature (in K)
zgs
A matrix of geopotential height (static variable, all rows are equal, in meters)
direction
Direction of the conversion, either "ps2psl" or "psl2ps".
Details
This function is a internal for the derivation functions ps2psl and psl2ps.
Value
A 2D matrix with reduced pressure data. Need to be reconverted to a grid using mat2Dto3Darray afterwards.
References
The adjustment formulae of pressure values to other levels are those routinely used by the WMO. These are described in the following technical report:
