Description (last modified by pesei)

Hi all
I try to calculate the daily P from 3-hr ERA5 data (from flex_extract),
first I change the format of ERA5 from grib1 to nc, and ncdump XX.nc, it says the LSP and CP is in unit m (which of course is wrong, the unit in mm is reasonable).

For the daily P from 3-hr ERA5 data, can i just sum all the time slot of one day,

For example, 2022-06-02, there are 8 time slot, 00:00, 03:00,06:00 …. 21:00, can I directly sum them together as daily P?

LSP_daily=sum (03:00,06:00 …. 21:00) at 2022-06-02 and 00:00 at 2022-06-03
CP_daily=sum (03:00,06:00 …. 21:00) at 2022-06-02 and 00:00 at 2022-06-03
P_daily=LSP_daily +CP_daily

Is it correct?

Best
