[RegCNET] OFFICIAL RELEASE OF RegCM4 !!!!

Thu Jul 29 18:36:24 CEST 2010

Hi Michael,
the lake model has not been changed nor tested in RegCM4, therefore I 
guess it will have the same problems as in RegCM3.
We hope to take care of this in the near future.
Best wishes
Erika

>>
>> 1) RegCM4 and its pre and post processors include extensive recoding,

>>
>> 2) From the point of view of physics, it includes CLM, the diurnal SST

>>   Dust). All other physics is like RegCM3.

>> 3) The tropical band (TB) option is still not included in this release. We
>>   still need to check a few things in it, and are planning to make a new

>>
>> 4) This code will be frozen until any new release is announced. Of course

>>
>> 5) We have the following items in the make (besides the TB option)
>>  5a) New UW PBL scheme
>>  5b) Tiedke cumulus convection scheme
>>  5c) Coupled ocean model (ROMs)
>>  5d) Coupled gas phase chemistry
>>  5e) Improved parallelization
>> We have the ambitious plan (hope?) to include all this into a new release at the end of 2010, but we will see how things develop and let you know.
>>
>> So please go ahead and start your transition to RegCM4. Note that from today we will not support any more RegCM3 in any way, so you might as well move to the new RegCM4 era. And of course please let us know of any problems or comments you might have.
>>
>> You may also know that we are planning to launch RegCM4 with a special journal issue. However, a few events beyond our control are delaying this process. I will give you an update on this as soon as the situation is more clear, but if you plan to have a paper for the special issue do not despair and keep working on it.
>>
>> Finally, let me take this opportunity to thank all the many people who have contributed to the development of RegCM4. I will not try to mention them all for fear of missing some of them, but their work was invaluable for the developemnt of this new generation code which will take us into 21st century climate modeling.

>> Have a good RegCM4-ing

>>
>> RegCM-4.0 is a major recoding of the previous RegCM3 version.  Since RegCM3 will no longer be supported,  we encourage all RegCM users to switch to this new model version.

>> -SeaIce introduced in the SST boundary

>> -Dust/Chemistry RegCM3 packages revised and improved

>> You can choose among different options and probably the most appropriate one for standard user are support and bugs.
>>
>> Remember when you report a bug or when you ask for support  to provide as much as possible the information about platforms/compilers/libraries and so on,  in order to help people to sort out the problem faster and in a more efficient way.
>>
>> Please take a few minutes to read http://eforge.escience-lab.org/gf/project/regcm  and try to submit bugs/request for help following such simple rules.
