Twitchell
8/25/2009

Arrive about 1pm with Oliver and Ben. Very little wind varying from west to north. Warm clear and sunny. Rice flowering heavily.

Atsushi installed his equipment north of tower last Friday, looks fine.

Everything seemed to be running. LGR was at 118 Torr. I adjusted the bypass value to bring to back to 142.

Still making clouds of dust to the west.

Ben and Oliver walked the transect for LAI, spectrum, etc.
