Hi Dennis:
The three flux files I sent to you are floor_flux.txt, tower_flux.txt and vaira_flux.txt. There were from floor, tower and grass system respectively. In these file, I only combined the Time, Fco2, LE, H and G.
The two txt files attached to this email are from last week (d131-136) at floor and Vaira sites . For Fco2 at floor and grass sites was in the range of +5 to -5 umol/m2s. At Floor system, daily max LE , H and G were at similar values about 100 W/m2. At grass site daily max H was around 300 W/m2, increased lot since last two weeks. While LE and G was around 100 W/m2.
We couldn't get the data at the tower site due to the computer problem. See the email from Ted for his explanations:

here are the notes for my trips last week and two txt file from the floor and vaira site.
5/17/01 At Tonzi Ranch:
in the morning, A_Ci curve measurement. mean of Vcmax was 93 umol/m2s. Around 12:10, downloaded floor system data and replaced li-Cor 75B-0041 with 75H-0065. Ted was at the Tower site to install the radiation and T/RH instrument.
At Vaira Site. 16:15
the grass season was pretty much over, only about 20% of grass heading was green and clover still green.
Download the flux data, and installed ref net radiometer.
