Strange slope values

[vibinj]

Hi, I am Vibin,
I ran the LDT without any error. But the slope variable showing some strange values over the land sea boundaries. Please help me. Because of these values I am getting error while coupling to NUWRF.
I have attached the ldt.log0000, ldt.config, lis_input.d01.nc files.
ldt.config.zip
ldtlog.0000.zip
lis_input.d01.zip

Thanks
vibin
