Hi,

 

I’m trying to convert OpenIFS Cy40r1 using operational model data
interpolated onto the normal reduced Gaussian grid and having 137 levels.
I’ve been using the following command:
grib_set -v -s editionNumber=1 ICMGGgruz+201701 ICMGGgruz+201701.grb
ICMGGgruz+201701
GRIB_API ERROR   :  Key "numberOfVerticalCoordinateValues": Trying to
encode value of 276 but the maximum allowable value is 255 (number of
bits=8)
GRIB_API ERROR   :  unable to set NV=276 as long (Encoding invalid)
GRIB_API ERROR   :  grib_set_values[0] editionNumber (1) failed:
Encoding invalid
Is there a work-around for this?
