Running into EnergyPlus Error when using generated files with 2021 data

[GFlechas]

I'm getting the following error from energy plus when I try to use weather files generated from 2021 data with diyepw, however I don't run into issues when I use files generated by the program for previous years (2018-2020). I'm trying to isolate if the problem is originating from diyepw or possibly the weather station data.

I'm calling the package as follows:
diyepw.create_amy_epw_files_for_years_and_wmos([2018,2019,2020,2021],[725650,724695,724660,724666],allow_downloads=True, amy_epw_dir=download_dir)

hi @GFlechas, when i ran your code locally, i noticed that no 2021 file was generated for 724695... is this is the same for you?

This appears to be because 724695 for 2021 is missing 53 air temperature records in a row, and the default allowed is 48. If you're okay with the missing data being imputed, you can override this behavior by calling like:

diyepw.create_amy_epw_files_for_years_and_wmos(
  [2018,2019,2020,2021],
  [725650,724695,724660,724666],
  allow_downloads=True,
  amy_epw_dir=download_dir,
  max_records_to_impute=54,
)

Hi @thurber, yes that is the same for me. I hadn't noticed that yet. There appears to be an issue with each of the 2021 files produced when I try to run a simulation with them.

@GFlechas , I'm quite rusty on running EnergyPlus -- could you try this experiment and see what happens:

Remove all the 2021 files and a single 2020 file, and try your simulation again to see if the same error occurs in 2020 now?

I ask, because i'm not easily spotting any substantive differences in the EPW files between 2020 and 2021
