hurs2huss: Relative humidity to specific humidity conversion

In SantanderMetGroup/convertR: A climate4R Package for Unit Conversion and Variable Derivation

Relative humidity to specific humidity conversion

Description

Relative humidity to specific humidity conversion using surface pressure and temperature

Usage

hurs2huss(hurs, ps, tas)

Arguments

hurs	Relative humidity grid
ps	Surface pressure
tas	Near-surface air temperature

Value

A climate4R CDM grid of specific humidity (in kg/kg)

Input units

In principle, the derivation functions will work regardless of the input units, as all units are internally converted as necessary according to the specific formulae definitions. However, the units string (see getGridUnits) must be parseable. In the same vein, the input units need to be convertible to the required ones. Unit consistency is internally achieved by the function udConvertGrid.

Examples

data("ps.iberia")
data("tas.iberia")
data("huss.iberia")
hurs <- huss2hurs(huss = huss.iberia, ps = ps.iberia, tas = tas.iberia)
huss <- hurs2huss(hurs = hurs, ps = ps.iberia, tas = tas.iberia)
identical(huss$Data, huss.iberia$Data)
# Not identical due to rounding errors:
range(huss$Data - huss.iberia$Data)
## Not run: 
require(visualizeR)
spatialPlot(climatology(hurs), rev.colors = TRUE, backdrop.theme = "coastline")

## End(Not run)
