Version 5 (V5) of the Level 2 (L2) files for US-SRM were posted.  The new
files provide data through 2010.  Fc values for 2004-2009 were revised from
previous versions of the L2 files.  Specifically, new Fc values were
re-computed after adjusting the WPL water vapor term resulting in very small
changes in Fc flux.

Scott by CDIAC to produce the posted V5 L2 files are provided at
