read_tuv_usrout: Read TUV output file.

In photobiologyInOut: Read Spectral and Logged Data from Foreign Files

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,
  ozone.du = NULL,
  date = lubridate::today(),
  geocode = NULL,
  label = NULL,
  tz = NULL,
  locale = readr::default_locale()
)

read_tuv_usrout2mspct(
  file,
  ozone.du = NULL,
  date = lubridate::today(),
  geocode = NULL,
  label = NULL,
  tz = NULL,
  locale = readr::default_locale()
)

Arguments

file	character string
ozone.du	numeric Ozone column in Dobson units.
date	a POSIXct object to use to set the "when.measured" attribute. If NULL, the default, the date is extracted from the file header.
geocode	A data frame with columns lon and lat used to set attribute "where.measured".
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.

Note

The ozone column value used in the simulation cannot be retrieved from the file. Tested only with TUV version 5.0.
