Db. Reserve funds – GUAN spares, other agreed activity Program management and administration 9 Routine / Fault GUAN station visits Present programme allows for one routine visit to Tarawa and Funafuti Both will be completed in May / June by engineers Three fault maintenance visits budgeted (VCP requirement), none needed so far. One fault visit remains in budget Budgeted funds for other two diverted (along with other savings) to training course and GUAN surveys 10 Penrhyn technician and “truck” (what’s left of it!) GUAN station supplies Regional spares kit established for: Proton Hogen 20 generators (Depot Kit) Digicora Other supplies as required, as can be funded e.g. Demineraliser cartridges Radar thyratrons Reimburse local costs Nothing needed so far 11 Balloon release, Tarawa, Kiribati GSN Station Inspection kits Designed and manufactured by MetService Three kits for TSP countries to do inspections and update meta-data, check instrument serviceability Inspectors barometer TSP GSN Station Inspection Kit 12 GSN Station Inspection kits TSP GSN Station Inspection Kit components 13 GSN Station Inspections Provides for Each country’s travel disbursements to do its GSN station inspections Freighting the kit Kit recalibration and replacement of used items Entry of returned meta-data from the inspections Funafuti Atoll, Tuvalu 14 91643 Program management & administration Provides for Management and administration functions that are associated with the TSP – internal and external • • • • • Coordination of program activities Financial planning and control Interactions with stakeholders Performance monitoring Reporting Meta-data database construction 15 Penrhyn radar – WF3 prototype – supplied 1977 Completed and planned work Completed work 16 • Remote support to GUAN stations – many areas • Enhanced GUAN/GSN performance monitoring and interaction with GUAN stations when data not received (as practicable) • Enhancing performance metrics • Facilitation of GUAN messages throughput • In-country support under TSP for some items e.g. replacement printer Port Moresby, power supply Funafuti • System spares – radar thyratrons – Penrhyn (in progress) • Establish GSN Inspection kits • GSN Station inspections (in progress) • Establish regional spares kits • Construction of meta-data reporting system (in progress) • GUAN station surveys – Port Moresby and Honiara • CLIREP, inspection kit training course • Programme management Completed and planned work Planned work – to 30 June 2005 • • • • • • • Routine station visits – Tarawa and Funafuti (June) Continue GSN station inspections Complete meta-data reporting system Supply thyratrons to Penrhyn Provide Honiara GUAN survey report Add PNG stations to performance monitoring Programme management Balloon release Port Moresby 17 Completed and planned work Suggested work – July 2005 – June 2006 18 Subject to GCOS objectives, priorities, approvals and funding • Continue TSP support and extend to any new/restored GUAN stations • One routine visit each year to GUAN stations (technical and management) • If GUAN station numbers increase budget three fault trips, undertake only if needed, otherwise budget two • Improve communications of upper air messages • Enhance performance metrics – GUAN and GSN • Continue station inspections, filing meta-data and sending to NCDC, kit re-calibration etc • Identify GSN station’s needs resulting from inspections • Establish CLIREP in each country, as required, with oneon-one mentoring Problems and solutions - GUAN Problems • You can’t rely on countries to keep you informed • Programs can just stop because bills havn’t been paid and supplier has cut them off, e.g. power and communications or there are technical issues • Consumables run out and the program stops • Message preamble is faulty causing messages not to file • Equipment develops a fault and no-one says anything Solutions • You must monitor stations’ output – daily if practicable • Ask questions if exceptions occur • Monitor stock holdings and request monthly stock on hand if returns aren’t routinely filed 19 Problems and solutions - GSN Problems • You can’t rely on countries to keep you informed • Communications, communications, communications – many issues – radio faults, ISP problems – congested systems Suspect instruments and observing practices • Staff performance issues • Message preamble is faulty causing messages not to file Solutions 20 • • • • Monitor performance – impractical to do so daily Improve communications systems Inspect GSN stations – inspections have started Advise stations of incorrect preambles Performance metrics We monitor station performance for GUAN and GSN in the region This process has been enhanced and expanded for TSP • PNG, Vanuatu, Solomon Islands stations added • Converting monitoring GUAN termination heights from altitude to pressure • We are trying to develop meaningful comparisons pre / post TSP stations’ Upper Air Stats -

GUAN Equipment is inspected routinely during GUAN station visits There is a Proton calibration that station staff have been instructed in but engineers check this during visits regardless No other calibrations are required of upper air equipment Proton training Tarawa 24 Inspections and calibrations - GSN Countries have commenced inspecting their GSN stations using TSP inspections kits We believe most stations will not have been inspected in 10 years Once the kits are returned and inspection data analyzed we will have a better idea of station instrument accuracies Instrument enclosure, Tarawa 25 Equipment Tarawa, Funafuti and Penrhyn All have “new” Protons and All have old Vaisala Digicora II ground stations that require upgrading to take RS-92 radiosondes Port Moresby Digicora I, upgraded by Bureau of Meteorology, for RS-92 Teledyne hydrogen generator 10 years old (an orphan) New hydrogen gas tanks, Tarawa 26 Equipment Bauerfield and Honiara Silent stations with unserviceable M28 hydrogen generators Digicora II both require repair and upgrading for RS92 Silent Upper air station, Honiara 27 Site meta-data GSN stations Underway with inspections process and creation of a metadata system for entering and storing data at MetService and passing to NCDC, copy to go back to country GUAN stations Really still to be done, but will by nature be less involved than GSN. Digicora testing, Bauerfield 28 RS-92 issues MetService approach to upgrading Digicoras We have issued an RFP to suppliers for our own stations and will await the outcome of that before making a recommendation to the UKMO regarding upgrading at Tarawa, Funafuti and Penrhyn The decision will be based on economics and include capital and consumable costs MetService has budgeted for the upgrade and the UKMO has kindly agreed to fund through their Pacific Trust Fund we administer 29 Digicora testing, Honiara..hot and humid – check out the shirt! Better than before We need to focus on demonstrating improvements as a result of the TSP GUAN Improvements to existing station performance – either better termination heights or improved numbers of flights per month But…existing stations numbers of flights (maybe Tarawa excepted) are not too bad…they would be a bit worse if not for the TSP but how do you show that? Bringing “silent” stations on line and lifting their performance 30 Not GUAN, included as some interest has been expressed in this station. We are holding a surplus, incomplete Digicora for it, donated by UKMO Upper Air Stats - March 05 35 30 25 20 Flights received 15 Max Possible 10 5 0 Penrhyn Rarotonga Funafuti Tarawa Better than before We need to focus on demonstrating improvements as a result of the TSP GUAN Can make some gains in going from 350gm to 700gm balloons – in progress for Tarawa and Funafuti and done for Penrhyn (not strictly ‘cos of the TSP but…) Change to 700gm Ensuring data gets to archiving centres Penrhyn GUAN - Mean and Maximum Termination Heights 40.0 Approx TRQ (hPa) 35.0 Approx MRQ (hPa) 15.0 10.0 5.0 Month / Year 05 Mar 05 Feb- 5 J an-0 Dec 04 Nov 04 O ct- 0 4 Sep 04 Aug 04 J ul- 0 4 4 J un-0 Apr - 0 4 04 Feb- Mar 04 0.0 May 04 31 20.0 4 Penrhyn termination heights 25.0 J an-0 Km 30.0 Mean Height Maximum Height Better than before We need to focus on demonstrating improvements as a result of the TSP GSN (to the extent that this is a priority) Establish CLIREP Improve communications (this will show an improvement in the performance metrics) Repair/replace instruments according to inspection results Continue inspection programs; maybe consider providing a GSN station inspection kit for each country Tony Veitch and Bill Witham discussing Honiara GUAN survey with Director, Chanel Iroi 32 Betio Atoll & Lagoon, Tarawa, Kiribati
