Problem with aeronet lat/lon locations #1888

Hi @perthsb. It sounds like you are wondering if a single METplus configuration file for ASCII2NC can convert multiple files from ascii to nc. The answer is yes it can. Please take a look at this ASCII2NC: Basic Use Case in our documentation, which help guide you through how to do that. You'll want to make use of the ASCII2NC_INPUT_TEMPLATE for your input data files. I hope that helps! |

If the station_id is the same, two or more AERONET V3 inputs can be concatenated. Otherwise the input is not accepted by ascii2nc because of the sanity checking by AERONET Site Name (which becomes the station_id for MET tools). Individual input file GSFC_20221202.lev15.txt is not processed by ascii2nc as is. Two changes at the input file are required to be processed by ascii2nc:
OR
Otherwise (input file can not be modified), ascii2nc should be enhanced 1) to ignore AERONET site name from the line 2 and 2) to get the "Date(dd:mm:yyyy)" and "Time(hh:mm:ss)" columns by parsing header line. The combined input file 20221202.lev15.txt: The sanity checking with AERONET Site Name should be disabled to support combined input with different AERONET Site Names. |

@perthsb it looks to me like this issue has been fixed in the main_v11.0 branch, which means it'll be fixed in the MET version 11.0.1 bugfix release. Let me describe the testing I did on this branch.
So we have about the same number of AOD/550 results as the number of headers. Am I correct in concluding that this issue is fixed for MET version 11.0.1, likely by dtcenter/MET#2383? |

@perthsb, thanks for letting us know. @perthsb and @AliciaBentley-NOAA, I see that Cactus is currently unavailable. When it becomes available, I'll grab Partha's data and will ask @hsoh-u to take a look. |

They were fixed already at 11.0 bugfix release.
print_pointnc2ascii.py is a standalone utility. It can be used after downloading from the github repository without building or installing steps. print_pointnc2ascii.py is available at print_pointnc2ascii.py for 11.0 bugfix and latest print_pointnc2ascii.py for 11.1 beta |

Thanks, @hsoh-u. @perthsb mentioned that with the bugfix release as asciitonc runs and creates netcdf file that the latitude and longitude of the station data is not changing, although the station name and AOD values change. He said there is an issue when he's running PointStat. I don't know exactly what he's running because I can't get to his script, run_Aeronet_ascii2nc.sh, on Cactus yet, but he seems to think that the latitude and longitude values are not correct. |

@jprestop and @hsoh-u thanks. I am sharing the location of file on Hera. Script to run is AERONET_AOD Tucson 20230326_235724 32.2330 -110.9530 779 Exact_Wavelengths_of_AOD NA 709.00 NA -999.00000000 That lat and lon is retained in the entire length and it never changes and that creates an issue with Point Stat as it reads only one station data. Hope this explains it now. Any help is appreciated. |

@perthsb and @AliciaBentley-NOAA, @hsoh-u has taken a look and has identified this problem as a bug. He created an issue: What is the impact of this bug? Will you need an 11.0.2 bugfix release to be installed on WCOSS2? |

Hi Julie. I'm asking Jason about the need for a MET bugfix this morning and
will let you know after that.

Hi Julie,
The impact of this bug is that we can't run the GEFS-aerosol component of
EVS on WCOSS2. We met with Jason this morning, and yes, we will need a
bugfix release (MET-11.0.2) installed on WCOSS2. How long do you think it
would take to 1) cut a bugfix release and 2) send us the necessary
responses to the WCOSS2 installation Google Form?
Take care,
Alicia

Hi,
I have opened a ticket few days ago with question related to ascii to nc and using pointstat. Reviewing the conversations of that ticket, I have found one question still remained unanswered or I need more information on that. Question is, if I have 100s of input ascii individual data files in an input data directory, can one Metplus ascii to nc conf will be able to convert all of them into 100 separate nc files ? Or I have to run for each input station ascii files. I put some example data points in Hera at (all *.lev15)
/scratch1/NCEPDEV/stmp2/Partha.Bhattacharjee/METplus/Scripts/Aeronet
Any help on this is appreciated.
