A3D

Format

This plugin reads legacy Alpine3D meteorological input files. It reads the meteo1d.txt file that contains, as measured at one unique location, the following fields:

  • air temperature in field ta
  • incoming short wave radiation in field iswr
  • wind velocity in field vw
  • relative humidity in field rh
  • incoming long wave radiation in field ea
  • precipitations in field nswc

and optionally a list of stations with their measurements (meteo2d files) for the following parameters (with YYYY being the 4-digits year):

  • precipitations (file named precYYYY.txt)
  • relative humidity (file named rhumYYYY.txt)
  • air temperature (file named tairYYYY.txt)
  • wind speed (file named wspdYYYY.txt)
  • and optionnally wind direction (file named wdirYYYY.txt)

Units

The units are assumed to be the following:

  • temperatures in celsius
  • relative humidity in %
  • wind speed in m/s
  • precipitations in mm/h
  • radiation in W/m²

Keywords

This plugin uses the following keywords:

  • METEOPATH: string containing the path to the meteorological files (ie: where to find meteo1d.txt and meteo2d files)
  • COORDSYS: input coordinate system (see Coords) specified in the [Input] section
  • COORDPARAM: extra input coordinates parameters (see Coords) specified in the [Input] section
  • COORDSYS: output coordinate system (see Coords) specified in the [Output] section
  • COORDPARAM: extra output coordinates parameters (see Coords) specified in the [Output] section
  • POIFILE: a path+file name to the a file containing grid coordinates of Points of Interest (for special outputs). Everything after a comment marker will be ignored until the end of the line.
