One question I often get is "how do you turn on EVP?". It is a little counterintuitive that SEAICEuseEVP=.TRUE. in data.seaice is ignored. Would it be OK if I added a couple of lines in seaice_readparms.F that specify a default SEAICE_deltaTevp ~ deltatT/120 when SEAICEuseEVP=.TRUE. ? Let me know Dimitris Menemenlis
