There was overcast skies, intermittent drizzling and calm weather.Sometimes it was sunny.

North west side two plots were harvested 2-3 days ago and there was green ratoon growth from stubbles in those plots.

There were no standing water in the plots. But canopy and land surface were wet due to intermittent drizzling.

Average LAI was 4.36 ( measured by LAI 2200 ). Average plant height was 96 cm.

The value of some variables at 2:00 pm as follows: Ts 24 deg C, pressure 101KPa , FC_wpl -0.03 mg/m2s, LE_wpl 128 w/m2, Hc 39 w/m2, Fm_wpl 128 ug/m2s, CO2 conc 720 mg/m3, CH4 mean 2340 ug/m3, H2O conc 20 g/m3, u* 0.2 m/s, tau 0.05 kg/m2, wind speed 1.00 m/s, wind direction 77 deg, diag_Li7700 15, rssi 15 (befor lens cleaning) and 54( after lens cleaning).

Beside these,? clean the lens of Li 7700 and Li7500. Washer liquid was added. Ts and flux data were collected from CR3000 only. Because, there was no data in the CR5000 CF card after last visit on 5 Oct . Thats why the CF card was formated.
