Description

This function reads and concatenates the daily SURFRAD files.

Usage

             test = NULL, progress.bar = TRUE, agg = 1, additional.variables = NULL)

Arguments

directory	the directory for files
use.original.qc	boolean, indicating whether the SURFRAD QC flags should be used
use.qc	boolean, indicating whether the built-in QC should be used
