RAFdataR Documentation

A sample data.frame as might be constructed by getNetCDF(), containing a short period of measurements from an NSF/NCAR GV flight in a project called "IDEAS-4". The data.frame contains a set of measurements, one row per second, and a "Time" variable.

Description

A sample data.frame as might be constructed by getNetCDF(), containing a short period of measurements from an NSF/NCAR GV flight in a project called "IDEAS-4". The data.frame contains a set of measurements, one row per second, and a "Time" variable.

Usage

RAFdata

Format

The data.frame contains 301 rows and 29 variables:
