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

Reported by: arajst Owned by: pesei

Component: FP input data Version: FLEXPART 9.0
Keywords: FNL data, FLEXPART 9.0, GRIB_API Cc: stakhilraj@…, sanjeev.esa@…


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

Kindly suggest some solution to resolve this problem.

With regards

Maybe you need a newer version of the grib_api, and you have to make sure that support for jpeg compression is activited in compiling the grib library.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

Thank you for your kind reply. I am using Ubuntu 18.04LTS. I will follow the steps and update you soon.

All ok?

comment:6 follow-up: Changed 2 years ago by arajst

Dear Pesei, Sorry for the delay in replying. I have tried to install eccode using the following steps

cmake /home/akhil/flexpart/eccodes-2.10.0-Source -DCMAKE_INSTALL_PREFIX=/home/akhil/flexpart/build2

this step it ran successfully, however, while running 'make' it's giving the following error,

Why don't you install the package from your Linux distribution as I recommended?

comment:8 Changed 2 years ago by arajst

Dear Pesei thank you for the fast reply. I tried to install libgrib2c0d for ubuntu. It didn't install. That's why I moved to eccode. The main thing is that i am not much familiar with Linux.

comment:9 Changed 2 years ago by pesei

What means "it did not install"? What exactly happened? And why are you again not trying the distribution package for eccodes?

(And please use proper trac syntax if you post code snippets or similar.)

As there is no answer since 16 months I assume the problem is solved.
