[Wrf-users] POST PROCESSING WITH RIP

[Eric Altshuler]

Hello Asnor,

If you are not using a cumulus parameterization on domains 3 and 4, convective precip will be zero on these domains, because all precip will be generated by processes that are explicitly resolved by the model. For all domains, whether or not a cumulus scheme is active, cumulative total precip is given by:

Total precip = RAINC + RAINNC

where RAINC is convective precip and RAINNC is non-convective precip. When comparing to observations, always compare TOTAL precip from the model.

Hi all users, 



Am just wondering with the post processing results which am using RIP. The problem is the output of convective cumulative rainfall was zero in domain 3 and domain 4; but there are a value in domain 1 and domain 2. On the other hand, in domain 1 and 2, I found that a huge of error from the modeled output and observed data of rainfall. Do you know what is going on at domain 3 and 4; and how to reduce the error for rainfall estimation from numerical model i.e WRF or MM5 in domain1 and 2? 

Many thanks in advance.

I don't have any idea. I'm a beginner with WRF! 

Cordially

Hi Hedde, 



May I ask you one question regarding the post process with RIP. When I extracted a time series data of convective cumulative rainfall and I managed to extracted the data at domain 1 and 2 but not at domain 3 and domain 4. The data shown zero value for all 17 days in domain3 and 4; actually there should be a value within this period due to comparison with observed data in this catchment. On the other hand, in domain 1 and 2, I found that a huge of error from the modeled output and observed data of rainfall. Do you know what is going on at domain 3 and 4; and how to reduce the error for rainfall estimation from numerical model i.e WRF or MM5 at domain1 and 2? 

Many thanks in advance.

Hi, 

if you're using the latest WRF 3.1.1 (if you're using and old varsion I've no idea): 
you have to translate the old key words. I joined a little perl pgm that will do the job. 
You can Look inside and you will find the translation to do : 



my %translate=("ucmcall "=>"sf_urban_physics", 

"pd_moist"=>"moist_adv_opt", 

"pd_chem"=>"chem_adv_opt", 

"pd_tke"=>"tke_adv_opt", 

"pd_scalar"=>"scalar_adv_opt" ); 

don't forget to translate the true values into "1" 



moist_adv_opt = 1, 1, 1, 

scalar_adv_opt = 1, 1, 1,
