In MCIP version 2, is the pass-through option for the PBL heights and radiation fields the default?
Yes, the pass through option for the PBL heights and radiation fields is the default option in MCIP version 2. There are a pair of options in MCIP version 2 for windowing MM5 data, the BTRIM and the I0/J0 options. How do these differ? What is the MM5 lateral boundary referred to in the run script? What is the recommended usage for these options? The BTRIM option is used to uniformly trim boundary cells off of the MM5 domain. The I0/J0 option is for windowing in on a portion of the MM5 domain. With the I0/J0 option you can trim the MM5 domain asymmetrically, where the BTRIM option only allows symmetric trimming around all boundaries of the domain. The MM5 lateral boundary is a 5 cell buffer on the outermost portion of the meteorology domain. This buffer is created to isolate the effects of the meteorology boundary conditions. For CTM applications, these cells should never be used as they are specifically created to wash out the boundary conditions from the meteorology model. To minimize
