Replacing parameter name with : AccPcp, AccPcp1h, tc, accpcp, accpcp1h + combination with "as_harp_parameter()" not helping

Closing this as it is the same as #46

eccodes doesn't understand that the parameter ID in these grib files, 206, is total precipitation.

I will prioritize getting a solution to this as soon as I can.

With some new features in harpIO, you should now be able to read these data. See #66.

For your case you would add the argument file_format_opts = grib_opts(...) as follows:

forecast <- read_forecast(
  start_date          = 2021022000, 
  end_date            = 2021022000,
  fcst_model          = "alaro_cy40_45km",
  parameter           = "Pcp",
  lead_time           = seq(0,3,1),
  by                  = "12h",
  file_path           = "/data/nwp/oper/grib/shmu",
  file_template       = "{YYYY}-{MM}-{DD}_{HH}/SURFPREC_TOTAL_{LDT2}.grb",
  file_format_opts    = grib_opts(param_find = list(Pcp = use_grib_indicatorOfParameter(206))),
  transformation      = "interpolate",
  transformation_opts = interpolate_opts(stations=station,
  clim_file           = "/users/ext005/app/harp/etc/geo_aladin45km.grb"),
  return_data         = TRUE,
  show_progress       = TRUE
)

I confirm, it works now. Thanks
