R Documentation

correctT

Description

Calculate time-response-corrected and dynamic-heating-filtered temperature variables for each temperature measurement in a supplied data.frame.

Usage

correctT(.data)

Arguments

.data

A data.frame containing measurements of air temperature and also airspeed (TASX), Mach Number (either MACHX or XMACH2), ambient pressure (PSXC) and water vapor pressure (either EWX or EDPC),

Details

For a data.frame supplied with some variables representing the air temperature, corrected values for each are calculated and added to the supplied data.frame. This routine is specific to the temperature sensors on the NSF/NCAR GV and C-130, either unheated Rosemount sensors or heated HARCO sensors, and it depends on conventional attributes in the NCAR/EOL/RAF netCDF files to determine how to handle each sensor. The supplied data.frame must contain additional variables as specified for the first parameter below.

Value

The supplied data.frame with new variables added that represent correction for time response (added with suffix "C") and replacement of the conventional dynamic-heating correction by a version filtered to match the time response of the sensor (added with suffix "F").
