Overview
The ICTP Regional Climate Model (RegCM), originally developed at the National Center for Atmospheric Research (NCAR), is maintained in the Earth System Physics (ESP) section of the ICTP. The latest version includes major upgrades in the structure of the code and its pre- and post- processors, along with the inclusion of some new physics parameterizations.

To configure the build system using the GNU make program should be enough on most systems to just type in:
| Code Block |
|---|
./configure |
The makeinc file must then be manually edited to uncomment an option line as described in the below diff:
| Code Block |
|---|
diff --git a/makeinc b/makeinc index edb543c1a..a42066da5 100644 --- a/makeinc +++ b/makeinc @@ -47,7 +47,7 @@ ifeq ($(findstring DCLM45, $(CPPFLAGS)),DCLM45) #CPPFLAGS += $(DEFINE)VICHYDRO endif -#CPPFLAGS += $(DEFINE)RCEMIP +CPPFLAGS += $(DEFINE)RCEMIP space := space += |

The above diagnostic printout of the surface pressure readings from the model internal status in hPa should show a constant pressure increase throughout the model run of about 10 hPa (mb) per month due to the radiative cooling of the atmosphere.
