How to calculate total precipitation rate in m/s

Postby makbar1999 » Mon Apr 02, 2018 6:50 pm

Hello All,
I am trying to calculate total precipitation rate in m/s. I am using RAINC, RAINNC, and RAINSH variables to do that, as follows:

do j=1,south_north
do i=1,west_east
do k=1,time
totalrain(i,j,k)=(rainc(i,j,k)+rainnc(i,j,k)+rainsh(i,j,k))/1000.0
enddo
enddo
enddo

do j=1,south_north
do i=1,west_east
do k=2,time
rainrate(i,j,k)=(totalrain(i,j,k)-totalrain(i,j,k-1))/3600.0
enddo
enddo
enddo

Here, 1000.0 is used to convert mm to meters, and 3600.0 is time difference in seconds between WRF output file sequence.
Does this code give me the precipitation rate at m/s at each node of WRF grid?
Thank you in advance,
M. Akbar

Come on WRF experts! If you know the answer, please just write a short reply. :D Should not take too long.
I searched online/WRF forums for the answer, but none of the related posts I saw has the explicit answer I am looking for. Thank you.
