lnfl can't run

[zuqian]

I have added the flag " -std=legacy "into the makefile.common ,however, there are still messages :

Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL STOP LINFIL COMPLETE 49.98user 0.18system 0:50.32elapsed 99%CPU (0avgtext+0avgdata 11476maxresident)k

when I run the examples ./lbl_examples/TAPE3_files/run_lnfl.pl . The lnfl codes are downloaded from the git clone "git clone --recursive git@github.com:AER-RC/LNFL.git". And when I build the lnfl using make ,there are many warnings like :

Warning: Line truncated at (1) [-Wline-truncation] COMMON /IFIL/ IRD,IPR,IPU,NWDR,LRC,ILNGTH,INLTE,IER,IPUOUT LN18920 1

Or

Warning: Possible change of value in conversion from REAL(8) to INTEGER(4) at (1) [-Wconversion] ../src/lnfl.f:2476:18:

         STR = STRSV/(VNU*(1.0-EXP(-BETA0*VNU)))                      LN12400
              1

How could I deal with it? Thanks

By the way , the OS is Centos 8(linux) and the gcc version is 8.4.1

@zuqian these are just warnings, not errors. STOP LINFIL COMPLETE means LNFL completed, so you should have a TAPE3 in your working directory. is that true?

@kcadyper am i missing anything?

Thanks for your reply! Maybe you're right ,I found the TAPE3 files output in my directory . And I take the TAPE3 files into the LBLRTM , there're also warnings like:

Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG IEEE_DIVIDE_BY_ZERO IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
STOP  LBLRTM EXIT 

It seems the TAPE12 output files are equal to the example files(TAPE12_ex).But I'm not sure whether the 'STOP LBLRTM EXIT ' is normal end . And will the warnings result in the wrong answers in the more complicated situations?

[zuqian]

By the way , if I want to set my own atmospheric profile (like using the ERA5 reanalysis) , is there any program may help me transport it to the TAPE5 file in the package ? Or should I type the TAPE5 files in my hands ? It' hard to processing lots of profiles.

yes, everything you're seeing is typical. you have nothing to worry about with regard to accuracy

because of LBL's flexibility, inputs are highly customizable. consequently, there is no "one size fits all" software for making the TAPE5 inputs. to handle many profiles (e.g., for CMIP/RFMIP experiments), i've typically used the lblrtm_instructions.html, -- which you should open in your web browser -- and written my own scripts that are specific to the application.

Hi,

'STOP LBLRTM EXIT ' is the normal ending. The warnings can be ignored. When LBLRTM fails the problem is normally is an error in the inputs.

Hi,

Yes, building TAPE5s by hand is time consuming. We normally write a Perl or Python script to build multiple TAPE5s. Basically we create a template with the fixed parameters, and have the script fill in the variable parameters. However, there are many different ways of setting up LBLRTM, so it is impossible to write a script that handles all conditions. Therefore you will have to write your own.

If you think it would help, I could send you a sample Perl script.

I'm appreciated for your kind reply .I would rather use python scripts to built up the LBLRTM TAPE5 .Thanks a lot!
