DRYAIR {TrenchR}R Documentation

Properties of Dry Air

Description

The function calculates several properties of dry air and related characteristics shown as output variables below. The program is based on equations from List (1971) and code implementation from NicheMapR (Kearney and Porter 2017; Kearney and Porter 2020).

The user must supply values for the input variables db, bp, and alt. If alt is known (-1000 < alt < 20000) but not BP, then set bp = 0.

Usage

DRYAIR(db, bp = 0, alt = 0)

Arguments

db

numeric dry bulb temperature (C).

bp

numeric barometric pressure (Pa).

alt

numeric altitude (m).

Value

Named list with elements
