Evaluation of uemep output in pyaeroval

[heikoklein]

Is your feature request related to a problem? Please describe.
The uemep-model produces air-quality output for different areas in very high resolution (up to 50m). The areas are usually in a projection, e.g. UTM-33 for Norway or LAEA for Europe and the output-files are often calculated in smaller subdomains which sum up to the total (tiles). Variables have also different names than those used for e.g. EMEP.
Example data are (thanks @eivindgw ):

• Europe in LAEA: /lustre/storeB/project/fou/kl/emep/ModelRuns/uEMEP/CAMEO/uEMEP/Jan2019_v1/
• Norway in UTM-33:
  • Tiles (daily and yearly per municipality): /lustre/storeB/project/fou/kl/emep/ModelRuns/uEMEP/Calculations/Mapping_2022_v4e/
  • Stations (hourly-file per dag, all known NRT stations): /lustre/storeB/project/fou/kl/emep/ModelRuns/uEMEP/Calculations/Stations_2022_v4e/

Describe the solution you would like to see
A pyaerocom config should exist to run these data. It should be easy to make the results available on the aeroval-test web-page.

Files are usually in one directory.
Files have two place-holders: datetime and tiles, e.g.
uEMEP_emep_report_2024_eecca_00166_20220101_00.nc
uEMEP_emep_report_2024_eecca_{tile:05d}_{date:%Y%m%d}_{utc:02d}.nc

data can be hourly to yearly, tile or date or utc can be omitted.

date and utc tiles can be concatenated with xarray.open_mfdataset, tile should be separately.

@eamousing @brucerd @eivindgw FYI

[heikoklein]

Files might contain hourly, or yearly output (maybe also daily and monthly output). Since it is not possible to see from the file what time-resolution it has (in particular if it only has one time-stamp), resolution should be given as additional parameter (ts_type)

EMEP4NO and similar emep runs in are input for uemep and should work, too. Requires collocation with projection information.

Example-file: /lustre/storeB/project/fou/kl/CAMS50/output_EMEP/202406/CWF_18AQNO-20240624_hour.nc

@eamousing @brucerd @eivindgw I would like to have an older, complete year EMEP4NO file, e.g. 2022 or 2020.

New test-dataset with uemep west-balkan data and ts_type in /lustre/storeB/project/fou/kl/emep/ModelRuns/uEMEP/EMEP_report_2024/west_balkan/tiles_test/

@heikoklein The EMEP4NO rerun 2022 output (one normal and one LF file per day) is here:
