Hi Michael!<br><br>For each vegetation type the minimum (xlai0) and maximum values (xla) of LAI  are prescribed in mod_bats_param.f90.<br>In BATS the LAI is varying between its minimum and maximum value. The variation is described with a seasonal function, which is based on temperature.<br>
This seasonal function is set to temperate climate (it is zero when the temperature is =&lt;0, and it reaches its maximum value (=1) at 25 Celsius and remains at its maximum at higher temperatures). LAI is computed in mod_bats_bndry.F90 (~l300), and the seasonal function is set in mod_bats_leaftemp.f90 (fseas).<br>
<br>Cheers,<br>Csaba<br><br><div class="gmail_quote">2012/6/19 Michael Notaro <span dir="ltr">&lt;<a href="mailto:mnotaro@wisc.edu" target="_blank">mnotaro@wisc.edu</a>&gt;</span><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
How is leaf area index treated in RegCM4 when run with either BATS or CLM?<br>
<br>
My understanding for CLM is that you can either run with prescribed mean seasonal<br>
cycle of LAI, based on MODIS, or run with an interactive LAI if CN is turned on.<br>
Is that right?  If so, how do you turn on CLM-CN?<br>
What about BATS?<br>
<br>
Thanks,<br>
Michael<br>
