read_uvspec_disortR Documentation

Read libRadtran's uvspec output file.

Description

Read and parse a text file output by libRadtran's uvspec routine for a solar spectrum simulation. The output of uvspec depends among other things on the solver used. We define a family of functions, each function for a different solver.

Usage

read_uvspec_disort(
  file,
  date = NULL,
  geocode = NULL,
  label = NULL,
  tz = NULL,
  locale = readr::default_locale(),
  multiplier = 0.001,
  qty = "irradiance"
)

Arguments

file

character string

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.

multiplier

numeric A multiplier for conversion into W m-2 nm-1, as the units of expression of the output from "uvspec" depend on the units in which the extraterrestrial solar spectrum data is expressed.

qty

character "uvspec" returns both irradiance and intensity with solver "disort".

Value

A source_spct object.

Note

Currently only "irradiance" is suported as qty argument as intensity is not supported by classes and methods in package 'photobiology'.

Tested only with libRadtran version 2.0
