Fix non-monotonic "eta_levels" in the namelist.input file

[Saszalez]

It is the first time that I find this message when running real "Fix non-monotonic "eta_levels" in the namelist.input file". I have searched but cannot find the explanation about what it means to be able to find the error and fix it. Some help?

Thank you.

Please send me your nameless.input to take a look. Which version of WRF are you running?

 

[Saszalez]

The version is 4.1

The namelist.input file is attached.

In our namelist.input, you set the eta levels as:
eta_levels = 1.0000000,0.9981300,0.9950206,0.9900648,0.9851324,
0.9802234,0.9692629,0.9572211,0.9394240,0.9047659,
0.8823364,0.7778343,0.6025906,0.4643588,0.3553220,
0.3097703,0.2693140,0.2169540,0.1868798,0.1731288,
0.1479569,0.1364473,0.1153784,0.1153784,0.0966662,
0.0800472,0.0585382,0.0000000,

Note that two levels (0.1153784,0.1153784) are the same in your settings. This is not allowed. Please modify and retry.

Thank you very much, it worked correctly. I read the set heights several times, but I didn't notice that there was a repeated one.
