Dear all, I wondered if somebody could explain me in a more simplistic way what the following parameters of the RegCM4.0's namelist file, as I am a beginner in running a model and don't know personally anyone here that has run the model before. Furthermore, I have read all the WIKI pages but, unfortunately, I can't understand these parameters: truelatl truelath smthbdy itype_in fudge_lnd fudge_lnd_s fudge_tex fudge_tex_s iotyp nspgx nspgd ehso4 h2opct (is the value 75 sufficient for the Mediterranean basin?) Any help would be invaluable. Irini Yiannikopoulou
