Dear Sander,

## We are trying to ingest the S5P\_PAL\_\_L2\_\_AER\_OT product using harp 1.20, running via

## Python 3.11.6 | packaged by conda-forge | (main, Oct 3 2023, 10:40:35) [GCC 12.3.0] IPython 8.16.1 – An enhanced Interactive Python.

Using the command:

* * *

operations = “;”.join([  
“aerosol\_optical\_depth\>50”, “keep(latitude\_bounds,longitude\_bounds,datetime\_start,datetime\_length,aerosol\_optical\_depth)”,  
“bin\_spatial(161,34,0.05,301,15,0.05)”,  
“derive(longitude {longitude});derive(latitude {latitude})”])  
reduce\_operations = “squash(time, (latitude, longitude, latitude\_bounds, longitude\_bounds));bin()”  
mean\_no2=harp.import\_product(files, operations, reduce\_operations=reduce\_operations)  
harp.export\_product(mean\_no2, output\_dir+‘s5p-NO2\_L3\_averaged\_20Aug8Sep2023.nc’)

* * *

We saw in the other post the trouble for harp 1.19, which is solved by excluding the qa filter. Even though we are using the newest harp, we also tried that and are still getting the error:

* * *

create\_daily\_period\_files\_AoT.py’, wdir=‘/mnt/lapsat/groups/lapsat/s5p\_no2\_from\_fires/s5p\_aot/Programs’)

Any ideas?  
Thanks  
MariLiza

Could you check whether you have a manually set `CODA_DEFINITION` environment variable (pointing to a different location from where HARP puts its codadef files)?  
The error you are getting indicates that the right codadef is not found.

I do have a CODA\_DEFINITION in my .bashrc file, which however is for the centrally installed harp 1.17, to use outside the conda envs, from the command line. It should not apply to the conda env I am using to try the code out.

* * *

## export IDL\_STARTUP=~/idl/idlstartup.pro export CODA\_DEFINITION=/mnt/apps/prebuilt/harp/1.17/share/coda/definitions export UDUNITS2\_XML\_PATH=/mnt/apps/prebuilt/harp/1.17/share/harp/udunits2.xml

Furthermore, my colleague Andreas is facing the exact same problem and he does not have any CODA\_DEFINITION whatsoever in his .bashrc file.

Any other ideas? the env I am using has installed only harp and spyder, both via conda-forge. Sending the list below just in case you spot something.

Recall that some time ago [back in January] we had trouble with the numpy version and the harp version? maybe something similar is happening here?

Many thanks  
MariLiza

I think it will still apply. You can check this from your python script by using `print(os.environ['CODA_DEFINITION'])`

Ok, I am getting a different error from Andreas:

MariLiza:

Andreas:

Ok. So in your case, the problem is that you are still referring to the codadefs of a HARP 1.17 installation. And you thus won’t find the codadef for the S5P-PAL products.

In the case of Andreas, there is indeed no explicit codadef path set, so there is another issue. Is he using HARP 1.20?

Re. my trouble. I took out the codadefs from my .bashrc and of course it worked, but I do not understand why. Doesn’t the conda environment superceed the local variables/local installation? well, it obviously doesn’t, but this mean that every time I update harp within my envs I have to ask the sys admins to also update harp in the whole system. Okeeey…

Re. Andreas, he is indeed using harp1.20, we both made new envs with just harp and spyder on. Let’s see what our local people can opine on his case.

Many thanks,  
MariLiza

You shouldn’t have to explicitly set the `CODA_DEFINITION` or `UDUNITS2_XML_PATH` at all.  
For the IDL interface, you should be setting `IDL_DLM_PATH`. See also the [HARP installation instructions](http://stcorp.github.io/harp/doc/html/install.html).

It should be enough to set the IDL\_DLM\_PATH, but for some reason I do not understand, it is not.  
In any case, this is not your trouble, but our sys admin’s so thanks again!
