Infrared gas analyzer (IRGA) failed 6/16; a new IRGA was installed on
6/30.  All data related to CO2 and water vapor concentration measurements
(including CO2 flux and latent heat flux) are incorrect for the period of
June 16, 2004, 17:30 to June 30, 2004, 17:30.  Wind and sensible heat flux data are OK.
