Questions for 25km East Asia domain experiment. – in #12: CCLM Starter Package Support

in #12: CCLM Starter Package Support

(Q1) cclm is part of the starter package cclm-sp (You can find the source in cclm-sp/src/cclm ). cclm-sp also contains int2lm and several scripts (see [[cclm-sp:Documentation|Starter Package Documentation]]).

(Q2) As a rule of thumb it is linear with grid width. The bias in T_2M is much too large. As it seems to reflect the orography, did you applied the mandatory orographic correction to T_2M before comparing with observations?

(Q3) You probably cross the date line in the larger domain. In that case put east_add_in=1 into the namelist GRID _IN in int2lm.

General remarks:
(!) A careful namelist setup of the model is a major basis for receiving satisfactory results. Since your domain is in the tropics I recommend to visit http://www.clm-community.eu/index.php?menuid=218&reporeid=302 (you need to login on the page first) and check under the section “Model Setup” the YUSPECIF and the OUTPUT files. These hold the information for a tropical setup for cclm version 4.8_clm17 and int2lm version 1.9_clm3. If you need namelists for newer versions maybe Hans-Jürgen Panitz has these already.
