Issue while running FLEXPART 9.0 with FNL 2014 and earlier years data.

Description

Dear all,

I am facing a problem while running FLEXPART 9.0 with FNL 2014 and earlier years data. It is showing the following error message.

GRIB_API ERROR : JPEG support not enabled.
GRIB_API ERROR : unable to get codedValues as double array (Function not yet implemented)
GRIB_API ERROR : gridcheckwind_gfs: Error Function not yet implemented.

However, the model is running perfectly with 15 January 2015 onward.
While posting this issue we noticed a related issue by Dr. Harish from Ahmedabad regarding FNL data from 14 January 2015
(https://www.flexpart.eu/ticket/220).

Kindly suggest some solution to resolve this problem.

With regards

Akhil

Maybe you need a newer version of the grib_api, and you have to make sure that support for jpeg compression is activited in compiling the grib library.

Thank you Pesei for your kind reply. We are using Grib_api1.26.1-source. We configured it without enabling jpeg, otherwise, it is not installing. Could you please suggest a method for the clean installation of grib_api higher version with JPEG enabled option. The following command we used for the installation of Grib_api

cmake ../grib_api-1.26.1-Source -DCMAKE_INSTALL_PREFIX=/home/akhil/flexpart/GRIB_API -DBUILD_SHARED_LIBS=OFF -DENABLE_JPG=ON.

I assume that you are on a Linux system. In Debian & its derivatives, there is a package libgrib2c0d which includes jpeg. You can also use eccodes (then you need to change your loader flags in the makefile accordingly).
