1 NAFE 2005 CS616 and Meteorological data T.Wells, C. Martinez, G. Hancock and J.D.Kalma Plan of talk: 1.Overview of the collected and missing data 2.Data/calibration issues 3.Data examples. NAFE workshop Feb 2006
2 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 0-300mm, mm, mm CS616 Soil Temperature(20min)0-50 mmThermistor 0-300mmT107 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 31 st Oct to 30 th 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 NAFE workshop Feb 2006
4 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
5 2. Data/calibration Issues. 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 a. Relay failures. NAFE workshop Feb 2006
6 c. Increased data traffic Installation of Hydraprobes and rain gauges -> increased data collection rate ~×2 Reducing data logger storage capacity from ~65 days to ~35 days Solution: 8 sites => 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 Data/calibration Issues (cont).
7 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 Data/calibration Issues (cont).
8 NAFE workshop Feb 2006 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?
9 NAFE workshop Feb Data examples – T variation Cullingral (M2) over NAFE period.
10 NAFE workshop Feb Data examples – Variation of near surface moisture. S1-Stanley; M2-Cullingral
11 M2 M3 M5 NAFE workshop Feb Data examples – Spatial variation of rainfall along Merriwa Catchment Midlothian Merriwa park Cullingral
