I'd like to run an experiment with daily lake surface temperature (LST) from satellite observations. I wrote the LST from satellite to the wrflowinp_d0* files and set SST_UPDATE =1. However, the LST in wrflowinp_d0* had no influence on the surface temperature over lakes when I analysis the SST from model output. Any comments or suggestions will be very much appreciated.
 
Can you upload your wrflowinp, wrfinput, namelist.input, and a few wrfout files for me to take a look? Thanks.

Hi Ming Chen,

Attached is my namelist.input. I can't add my wrfinput, wrflowinp, and wrfout files to the attachments. Is there an alternative way to send those files to you?
By the way, I have three domains, and I set sst_update =1, in my namlelist file. Should I set sst_update=1,1,1, in order to tell wrf read SST from wrflowinput for the nested domains?

Best,
Qi

Attached is the comparison between WRF lowinput sst and WRF output sst after 13-day simulation. As you can see, the outer domain has the same SST output as the lowinput sst. But the second and third domains don't have the updated sst.

Best,
Qi

Please change the option in your namelist.input from

auxinput4_interval = 360,

to:

auxinput4_interval = 360, 360, 360

Then try again. Please let me know whether this option fixes the problem.
