LMDz photorates (LMDZ / photochem)

Description

This plugin reads LMDz ‘kinetic’ input files

Example of use

datavect:
plugin:
  name: standard
  version: std

components:
  kinetic:
  plugin:
    type: field
    name: LMDZ
    version: photochem
  dir: /path/to/kinetic/directory
  file: kinetic.lmdz9696.%Y.%m.nc
  file_freq: 1MS

The following structure is excepted for the NetCDF files (the photolisys rates 'jXX' are optional):

dimensions:
  time_counter = 31 ;
  lat = 96 ;
  lon = 96 ;
  presnivs = 39 ;
variables:
  int64 time_counter(time_counter) ;
    time_counter:units = "days since 1985-01-01" ;
    time_counter:calendar = "proleptic_gregorian" ;
  float lat(lat) ;
    lat:axis = "Y" ;
    lat:standard_name = "latitude" ;
    lat:units = "degrees_north" ;
    lat:valid_min = -90.f ;
    lat:valid_max = 90.f ;
    lat:long_name = "Latitude" ;
    lat:nav_model = "Default grid" ;
  float lon(lon) ;
    lon:axis = "X" ;
    lon:standard_name = "longitude" ;
    lon:units = "degrees_east" ;
    lon:valid_min = -180.f ;
    lon:valid_max = 176.25f ;
    lon:long_name = "Longitude" ;
    lon:nav_model = "Default grid" ;
  float presnivs(presnivs) ;
    presnivs:axis = "Z" ;
    presnivs:standard_name = "model_level_number" ;
    presnivs:units = "sigma_level" ;
    presnivs:valid_min = 1.f ;
    presnivs:valid_max = 39.f ;
    presnivs:title = "sig_s" ;
    presnivs:long_name = "Niveaux sigma" ;
  float temp(time_counter, presnivs, lat, lon) ;
    temp:long_name = "temperature" ;
  double pmid(time_counter, presnivs, lat, lon) ;
    pmid:long_name = "pressure" ;
  float j01(time_counter, presnivs, lat, lon) ;
    j01:long_name = "photolisys rates" ;
