Problem with the actual meteorological file from the NOAA dataset

[Kay]

Hello,

I am trying to create an AMY for the Los Angeles 2020 year data obtained from the NOAA dataset at Data Search | National Centers for Environmental Information (NCEI) (noaa.gov).

The generated .epw file(included in the .zip file) looks like its got the diurnal and nighttime temperatures wrongly distributed. Is there a problem with the time series data in the CSV file and can anyone suggest a way to fix this?

I would be grateful for the help.

Thank you,
Kay

I have attached the files that I referenced in the post.

You might have the hours not adjusted correctly for the time zone. If you’re generating AMY EPW for 2020, feel free to try this tool to compare.

@josephyang is correct!

You have to change the _time_zone_ integer when you import the NOAA data since this info doesn’t come included in the CSV that you download:

You see that all of the data is imported correctly when you use Pacific Time (GMT -8).

Thank you @josephyang and @chris!
