In 12 Aug 2007, I went to Tonz/Vairai sites by myself. I measured spectral reflectance and LAI. At Vaira site, I only measured reflectance around LED sensor and the flux tower. All grass is dead so I did not measure under trees. For Tonzi site, I measured reflectance in reference 1&2 grasses and LAI around tram system. I went up/down the flux tower nearlly 10 times for my mistakes. Finally, I collected 80 pts LAI around tram. Leaves of blue oaks turned to yellow. Dennis said this is a first observation for falling leaves in Aug. It looks due to short growing season length modulated by little precipitation in May and June. Extremely dry and hot. Clear sky, moderate wind at the top of flux tower. Tram did work. I left Berkeley 14:45, arrived in Vaira 16:45, arrived Tonzi 17:30, and left Tonzi 20:30. I prepared Bibimbob for dinner, but forgot to bring a spoon.....
