Summary: Lots of rain the last few days, Updated sap flow data logger programs, Moisture Point readings

WHO: Nancy Kiang, Jianwu Tang
WHERE: Tonzi Ranch
WHEN: 3/8/02
WEATHER: 60 F. Clear after 2 days' rain (1")
WHAT: Load new CR10X program onto sapflow data loggers to do more data processing. Record Soil Moisture Point sensors.

Arrived 10:20 PST. 60 F, clear sky after 2 days' rain, lots of standing water on ground. Mr. Tonzi says last two days' rain were 1", and total this year is 19".

SAPFLOW: Loaded new program onto tz4 and tz5 CR10X's, SFHRAT3C.csi. This program increases the frequency of data sampling from once per hour (previous program) to every half hour, and returns the following fields:
time, battery voltage, initial temperatures (30), mean(log(temperature
change ratios)) (15)

The mean(log(temperature change ratios)) for each half hour are returned for calculation of heat pulse velocities following the heat ratio method (Burgess, 2001). Each half-hourly value must be post-processed to correct for sensor misalignment before calculating heat pulse velocities and integrating to tree sapflow.

SOIL MOISTURE POINT: Took replicates of 3 measurements each from the Moisture Point sensors, new data in:
Ione 1:\Sites\Tonzi_oak_savanna\Soil_Property\Soil Moisture\ Soil Moisture Profiles Moisture Point MP 917.xls
