  Initial Request
----------------------------------------------------------------

Good morning,
I need you advice on what to do when I dont have the level for the
point observation
ASCII file
<https://dtcenter.org/metplus-practical-session-guide-july-2019/session-2-grid-obs/met-tool-ascii2nc-0>
is it better to input 9999 as missing value or 1 since it is hourly data ?

Thank you

Tatiana

ascii2nc reads and saves values as is. It does not handle the missing
value. MET tools use -9999 as missing value internally. It's better to
put -9999 as the missing value.

Cheers,
Howard

Thank you. the nc file will be used for pointstat and MODE. Does this
change things?

I'm sorry for the late response.

The missing values are ignored by pointstat and MODE. If the missing
value is not specified, they will be processed as the valid data.

Cheers,
Howard
