Specifies the meteorological parameter of a field.

param=<value>

It is recommended to specify a meteorological parameters by its unique parameter ID, e.g. param=132044, or by a combination of  indicator of parameter and GRIB table 2 version in the form param=indicatorOfParameter.table2Version. Other ways of specifying a parameter are by using their GRIB code (param=130), their Parameters can only be specified by their short name (param=t) or their full name (param=temperature).

  • Meteorological parameters available in dissemination and their definitions are listed in the Catalogue of real-time products. The following additional sources of information might be useful
  • Parameters database - lists all parameters (which can be handled by the ECC software) according to their GRIB definition

Examples:

param=t/u/v,                                                 #   short name                                                                       # specifying the parameter "temperature" by
param=130.128                                    #   indicator of parameter and table 2 version
param=130                                             #   parameter ID
param=t                                                   #   short name
param=temperature                         #   full name
param=129/134/167                      # parameters geopotential,  surface pressure and
                                                                   # 2 metre temperature
