Title: NAFE 2005
1NAFE 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.
2NAFE 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
-
3NAFE workshop Feb 2006
4NAFE workshop Feb 2006
i.e. collected all data from Stanley weather
station but none from Spring Hill over the NAFE
campaign period due to logger failure
5NAFE 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
6NAFE 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).
7NAFE 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.
8NAFE 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?
