Transfer to Ops: Requirements at the Canadian Meteorological Centre David Anselmo Air Quality Modelling Applications Section Meteorological Service of Canada Montréal, Québec David.Anselmo@ec.gc.ca Data Assimilation Fusion Meeting Downsview January 16-17, 2012
2
Page 2 Outline Requirements for an operational implementation –Make the case (identify the need) –Data readiness (observations) ▪Top 4 –System readiness Common challenges to ops transfers Advantages to going operational
3
Page 3 Identify Need from Program Perspective What?... products are to be generated in ops Who?... are (potential) clients of the products –SPCs/forecasters, Weatheroffice/general public, other operational systems Why? … –Identify the benefits of the products –Does it have to be operational to realize full benefit? –What is the importance of near real-time? How/Where? … will users access the products –Is development necessary? –Are other groups involved?
4
Page 4 Data Readiness – Top 4 Data availability –What is source of data? ▪Are transfers to CMC already established? Can they be? ▪Would data transfer make use of existing links to CMC? ▪What are protocols for data transfer from provider? ▪Are they reasonable/acceptable to CMC? –Bandwidth, security concerns –What is format of data? ▪Is it new to CMC operational systems? Is there precedence? ▪Is software in place to decode this format? –What are long term prospects wrt data availability? ▪Longevity, continuity of observing programs ▪Dependence on other countries (changing budgets, priorities)
5
Page 5 Data Readiness – Top 4 Data reliability –Is upstream data processing supported by provider? ▪Is it supported 24/7? –How are unexpected outages or routine downtimes addressed? –What is normal frequency and duration of outages & downtimes? –What is overall percentage of data availability? ▪Is it acceptable for operational system? ▪Is it acceptable for clients (assuming a dependency develops)?
6
Page 6 Data Readiness – Top 4 Data quality –What is usability of data? –What quality measures are in place at source? ▪Quality assured data ▪Quality controlled data –Does data arrive with pre-applied flags? –What additional measures must be applied before data can be used operationally? ▪Must assess negative impact on downstream users from poor quality data
7
Page 7 Data Readiness – Top 4 Data timeliness –“Latency, latency, latency.” –For many apps, if data does not arrive in time, it is essentially useless –Define what is “late” for the intended application ▪Concept of a cut-off ▪For some programs T+9h, for others T+30min Operational Near Real-Time –Is the entire transmission system “operationally capable”? ▪Though, it need not be operational!! (Ex. satellite)

Page 9 System Readiness Applies to applicant system as well as host environment CPOP considerations (Comité des passes opérationelles et parallèls) –Advance planning ▪Resource allocations (human & computer) ▪Balance/coordination with other implementation requests ▪Initial proposal 12-18 months in advance –Coordination with existing operational components ▪Impacts & dependencies between upstream & downstream systems –Ex. Global model, Regional model, AQ model, UMOS, OA, etc ▪Regional SPCs (forecast scheds), Weatheroffice, etc Commonality of working environment (tools) –Research Development Operations –To reduce AMAP duplication of work; streamline implementations –Ex. Job sequencer (OCM/Maestro)
10
Page 10 System Readiness System diagnostics –Monitoring of the reliability, quality, timeliness of input –Performance measures ▪Routine verification of quality of final products
11
Page 11 System Readiness Documentation –Creation of standards for evaluation and future upgrades ▪What are conditions for implementations? –Define procedures for future parallel runs (seasons, length of time, etc.) –Verification scores & thresholds –Against observations/analyses –Subjective evaluations by A&P ▪Identify dependant systems that must undergo impact assessments with every implementation –Support documentation ▪Assist 24/7 support teams (NetOps, CMOI, A&P) ▪Problem scenarios & remedy procedures ▪Contingencies for data or system outages –GENOT, Technical note, CMC product guide
12
Page 12 System Readiness Outreach –Presentation to CMC building prior to formal CPOP proposal ▪Present in detail the science and implementation plans ▪Present future directions ▪50 minutes –Formal CPOP proposal for parallel run ▪Brief summary of science and implementation plan ▪15-20 minutes ▪Voted on by CPOP members
13
Page 13 Common Challenges to Ops Transfers Each implementation = additional cost –Competition for limited resources The first implementation is resource intensive –Often requires significant adaptation to conform to operational expectations ▪New data types & formats & paradigms –Tests communication links between R, D, and O Maturity or lack thereof of component(s) –Observation infrastructure, robustness of methodology, etc. Increased complexity for assimilation systems –Marriage of 3 components: observations, model, methodology Adaptation to continual evolution of… –Computing environment –Upstream/downstream systems
14
Page 14 Advantages to Ops Status Demonstrates important value/purpose of system Provides continuous monitoring to identify issues with data –Quality, timeliness, etc. –In turn, opportunities to improve data stream (feedback to data providers) Improves product availability & visibility Can be supportive to other operational systems –Ex. sensitivity of GEM-MACH has proven an effective means of debugging dynamics & physics libraries shared by other models
