Hello, I find the brief introduction that  "What's New in CESM1.2.0" in http://www.cesm.ucar.edu/models/cesm1.2/tags/cesm1_2/whatsnew_science.html.I am interseted in  the detailed information, especialy the "CAM-WACCM" and the "Updates for specified dynamics (SD-WACCM and SD-CAMchem, functional)". What is the difference between FSDW in CESM1.2.2 and FSDW in CESM1.0.4.  However, I cannot find the documents.Could someone help me? Jeff

Here is the full list of WACCM updates in CESM1.2 that we submitted for the release notes. The indents got lost on the web page, apparently. The SD-WACCM updates are just extending inputs to include more recent dates, and changing the namelist variable that controls the nudging factor.[*]New WACCM4 CARMA compsets yet to be created 
  • Stratospheric black carbon for nuclear winter studies (scientifically validated)
  • Sulfate: specified dynamics compset, heterogeneous chemistry to be added (functional)
[*]WACCM spectral element (SE) dycore support (functional)[*]Updates and bug fixes for specified chemistry (SC-WACCM, functional)
  • ozone file fixed
  • TMS on
  • documentation to be created
[*]Updates for specified dynamics (SD-WACCM and SD-CAMchem, functional)
  • SSI/TSI and Kp files updated for 2012
  • SPE and SAD file updates for 2012 to be created
  • new namelist specification for nudging factor (time scale, rather than percent)
[*]WACCM5 updates and bug fixes (functional)[*]Chemistry updates in waccm_mozart (functional)[*]Remove obsolete waccm_mozart_v1 chemistry package[/list]

Hi Mike,   In SD-WACCM in CESM1.2.2 for the nudging,  'met_max_rlx' is for the percent, and the default value is 0.1. It means 10%, ins't it?   what is parameter for the  time scale? what is the method? Could you give  more detail description?Wishes,Ying—studying
