Field Notes

12/11/2008 (346) Viara

Joe and Hideki arrived about 10:30 am. Data checked and downloaded. Weather was clear and sunny with calm wind. Hideki made soil moisture measurements. Joe did spectral measurements and collected grass samples.

Phenology: To my untrained eye trees seemed to have about 50% leaf remaining most tending towards yellow. Ground is tinged with green as new grass emerges – maybe only a cm or two in height.
