Shashi Verma and Andy Suyker reviewed the Version 1 of the L3 and L4 files 
available for the Mead, Nebraska sites and discovered problems with the
storage terms, gap-filled NEE estimates, and ustar determinations.  In April 2008,
Shashi Verma & team provided new L1 files containing Fc values not screened
for stationarity or with nighttime adjustments for low windspeed.  The new L1
data also contained gap-filled NEE, H, and LE data along with records for the
same variables with gaps.
