How to extract time of a certain duration from given .nc series?

[diksha922]

Hello @StefaniaGrimaldi.

I have the dataset in .nc file for the larger period, I want to extract the dataset for a particular duration in LISFLOOD-compatible input format.

Can you please help with this?

Thanks,

Dear @diksha922,

you can select the start date and the end date of your simulation using the .xml settings file:
https://ec-jrc.github.io/lisflood-code/3_step3_preparing-setting-file/

"StepStart" and "StepEnd" allow to set the start date and the end date of your simulation.

If your forcings are from 02/01/1979 00:00 to 01/01/2020 00:00, but you only need to perform a LISFLOOD run from 02/01/1990 00:00 to 02/01/1995 00:00, you can set:
"CalendarDayStart" = 02/01/1979 00:00
"StepStart" = 02/01/1990 00:00
"StepEnd" = 02/01/1995 00:00

OS LISFLOOD will only use the forcings from StepStart to StepEnd, even if your .nc files include many more years.

As a side note, please be aware that the LISFLOOD pre-run must cover an extensive period to allow adequate initialization of all model states (it is recommended to use all the available forcings): https://ec-jrc.github.io/lisflood-code/3_step5_model-initialisation/.

I hope that my answer helps,
kind regards,
