read_tuv_usrout: Read TUV output file.

Description

Reads and parses the header of a text file output by the TUV program to extract the header and spectral data. The time field is converted to a date.

Usage

read_tuv_usrout(file, date = lubridate::today(), geocode = NULL, label = NULL, tz = NULL, locale = readr::default_locale())

Arguments

file
character string
date
a POSIXct object, but if NULL the date stored in file is used, and if NA no date variable is added
geocode
A data frame with columns lon and lat.
label
character string, but if NULL the value of file is used, and if NA the "what.measured" attribute is not set.
tz
character Time zone is by default read from the file.
locale
The locale controls defaults that vary from place to place. The default locale is US-centric (like R), but you can use locale to create your own locale that controls things like the default time zone, encoding, decimal mark, big mark, and day/month names.

Value

a source_spct object obtained by 'melting' the TUV file, and adding a factor spct.idx, and variables zenith.angle and date.
