MAGDA Weather stations to WRF

This module can be used to convert weather stations observations in MAGDA format into ascii WRF format.

Installation

The module use go-netcdf to read a netcdf containing world orography data.

In order to use it, you need the developer version of the library provided by your distribution installed.

On ubuntu you can install it with:

sudo apt install libnetcdf-dev

On Typhoon, it can be loaded with the WRF-KIT2 module:

module load gcc-8.3.1/WRF-KIT2

The orography data is used to calculate the altitude of every weather station given their latitude and longitude coordinates.

You can download the orography file from https://zenodo.org/record/4607436/files/orog.nc

The file must be saved in path ~/.magda_ws2wrf/orog.nc

Usage on CIMA Typhoon

An orography file is already usable by wrfprod user: /data/safe/home/wrfprod/.magda_ws2wrf/orog.nc.

magda_ws2wrf is already present in /data/safe/home/wrfprod/bin/magda_ws2wrf

Command line usage

This module implements a console command that can be used to convert observations from CSV to ascii WRF format.

Usage of mag_ws2wrf:

mag_ws2wrf [options] <input file>...
Options:
  -date string
        date and hour of the stations data to filter [YYYYMMDDHH]
  -domain string
        domain of the stations to filter [MinLat,MaxLat,MinLon,MaxLon]
  -outfile string
        where to save converted file (default "./out")

• can be specified more than once. When multiple files are specified, their data is concatenated in a single output ASCII file.
• if date option is specified, only measurement of the date will be converted
• if domain is option is specified, only stations contained in that domain will be converted
• if no date or domain option are used, all data in input files is converted.
