wrfpress giving null values in some grid cells

Postby Vins_94 » Fri May 21, 2021 11:12 am

Hi,
I am trying to run WRF with following namelist options. But when I used aux_hist23 option with custom pressure levels for wrfpress_d01_<domain><date>. The output has lot of missing values where as, wrfout* file has proper values for u and v variables. when I try to extract them for particular pressure levels, some of the values go missing in wrfpress. Is this behaviour normal??. I have compared the pressure levels between metemfiles and my custom levels in &diags section in namelist. everything seems correct. Please help.
