# standard_atmosphere: Standard Atmosphere calculations In RAtmosphere: Standard Atmospheric profiles

## Description

This function calculate Temperature, Pressure and Density of air at a fixed quota, according to ground temperature, density and pressure. The profile is a standard atmospheric profile according to 1976 Standard Atmosphere.

## Usage

 `1` ```standard_atmosphere(z, vout = 3, T0 = 288.15, P0 = 101325, R0 = 1.225) ```

## Arguments

 `z` Altitude over see level in meters. It can be Vector, Matrix or scalar value. `vout` possible vaues are: 1 for temperature (output in °K) 2 for pressure (output in Nm^-2 3 for density (output in kgm^-3) `T0` Scalar value. Temperature at see level [°K]. `P0` Scalar value. Pressure at see level [Pa]. `R0` Scalar value. Density at see level [kgm^-3].

## Value

According to input z the function will return a Vector, a Matrix or a Scalar value, according to the specified vout.

## Note

This function is general, no latitude-longitude or seasonal specification. It is necessary to evaluate a standard backscatter profile.
