Lats4d can average GRIB and any other grads readable format. See here:

    http://opengrads.org/wiki/index.php?title=Lats4D

There are some recipes illustrating the use of lats4d, for example

http://cookbooks.opengrads.org/index.php?title=Recipe-017:_Subsetting_and_reformating_MERRA_data_with_Lats4d

http://cookbooks.opengrads.org/index.php?title=Recipe-018:_Regridding_of_MERRA_data_for_comparison_with_other_reanalyses

Lats4d is included with the OpenGrADS bundle, see http://opengrads.org
