Title: NAFE 2005


1
NAFE workshop Feb 2006
NAFE 2005 CS616 and Meteorological data T.Wells,
C. Martinez, G. Hancock and J.D.Kalma
  • Plan of talk
  • Overview of the collected and missing data
  • Data/calibration issues
  • Data examples.

NAFE workshop Feb 2006
1. NAFE/SASMAS Site data Overview. 26 SASMAS
sites in total 16 directly involved with
NAFE Data collected at NAFE/SASMAS sites Soil
Moisture (20min) 0-50mm Hydraprobe 0-300m
m, 300-600mm, 600-900mm CS616 Soil
Temperature (20min) 0-50 mm Thermistor 0-300
mm T107 Rainfall (0.2mm, timed to
second) Tipping bucket raingauge Radiation,
Air T, humidity, wind speed, added soil T
(20min) K6, S2 weather stns
  • Majority of data was successfully collected over
    the 31st Oct to 30th Nov period
  • 100 of available data collected at 9 sites
  • Data awaiting final data collection (this
    week) at 2 sites
  • Data lost due to mechanical failure at 5 sites

i.e. collected all data from Stanley weather
station but none from Spring Hill over the NAFE
campaign period due to logger failure

NAFE workshop Feb 2006
2. Data/calibration Issues.
a. Relay failures.
  • Relays were installed to allow sampling of
    Hydraprobe data
  • Relay failures at 8 sites (usually 3 to 7 days
    after installation)
  • ? K1,K2,M1- (fixed) and K5, M4, M6, M7, G1 to
    be fixed
  • Relay operation at G2-G6 will be assessed in the
    next few weeks.
  • Faulty relays will either replaced or repaired
    over next 2 months

b. Battery failures
  • 12V battery failures at Illogan, Roscommon and
    Spring Hill
  • Cause additional load due to installation of
    Hydraprobe, relay and telemetry
  • Solution upgrading of solar panels and
    replacing batteries (done).
  • Sites are now functioning normally

NAFE workshop Feb 2006
2. Data/calibration Issues (cont).
c. Increased data traffic
  • Installation of Hydraprobes and rain gauges
  • -gt increased data collection rate 2
  • Reducing data logger storage capacity from 65
    days to 35 days
  • Solution
  • 8 sites gt upgraded data 2Mb loggers
  • 13 sites with telemetry,
  • 5 sites to be further assessed for telemetry
    with directional antennae
  • Installing of telemetry and 2Mb data loggers
    underway (1/2 completed).

NAFE workshop Feb 2006
2. Data/calibration Issues (cont).
d. Data Processing.
  • All available SASMAS data for 2005 has been
    processed.
  • Processing of Hydraprobe data awkward esp. when
    data is intermittent
  • Will chase up Hydraprobe manufacturer for maths
    to input directly into XL
  • Processed data now includes Chris R.s new CS616
    calibration equations.
  • Have assumed that deeper probes at each site
    share the same calibration equation
  • Data will be available on SASMAS website in next
    few weeks.

NAFE workshop Feb 2006
2. Data/calibration Issues (cont).
e. Calibration
  • Several sites do not have separate calibration
    equations for 0-300mm CS616 probes (K1, K4, S5,
    S7)
  • Equations for deeper probes v. limited
  • Program of taking routinely 300mm soil cores at
    random sites during download field trips has
    commenced to check calibration equations.
  • Are the remaining (0-300mm) calibrations to be
    done in Newcastle or Melbourne?
  • Calibrations for deeper probes?
