What are forecast services? Roadmap for setting-up a forecast system

• Antecipate hazard situations and support emergency

• Guide management decisions to minimize risk

• Support coastal economy daily tasks as well as leisure and recreation

Forecast Framework


Forecasts services: current limitations

• A very demanding work

� Mixed teams: computer science, coastal engineers,

numerical modelers

� Large effort of development, deployment and

maintenance

� Requires significant computational resources

• Challenges

� Forecasts as a service

� Available to all users (not necessarily with IT expertise)

� Flexible (in the models and their versions, in the coastal

processes, in the user requirements)

� Take advantage of existing services and data (ECMWF,

NCEP, CMEMs and other regional/global predictions;

EMODNET and other data providers)

� Take advantage of existing infrastructures (INCD, EGI,

EOSC, MACC…)


The concept of OPENCoastS

Goal: establish and maintain a circulation forecast system deployed at

the site chosen by the user

� Deployment through a simple, user-friendly web interface, with a clear

sequence of steps

� User selects the site, the model, the forcings, the data sources and the

computational resource provider

� Easy to update, duplicate and extend for longer periods

� You can do it alone or with your team

� From data/results confidenciality to open data/results – all scenarios are

possible


Overview of OPENCoastS: starting a deployment

1) What do I need?

• Just a computational grid for my

domain of study

• Know the horizontal coordinate

system (e.g. WGS 84 –lat/long) and

vertical reference (e.g.+2 m relative

to mean sea level)

3) Next, just follow the steps (going back as needed,

leaving session when you want to restart later,…):

2) Then access the OPENCoastS link in

your browser:

• reference (typical) run: 60h cpu + 3GB storage / 72h

period daily forecast

• Large run : 600h cpu + 30GB storage / 72h period daily

forecast

• Very large reference run: 1200h cpu + 60GB storage / 72h

period daily forecast

(Note: cpu = xeon v4 @ 2ghz)

• Preservation plan and

implementation

• Software to handle model

versioning in a transparente

way

Atlantic vision for OPENCoastS

• LNEC and LIP have implementedOPENCoastS (.pt) for PT (INCD) andare porting it to the European coasts(EOSC-Hub)

• Expanding forecast deploymentcapacity to the whole Atlantic is a possible next step

• Past modeling works candidates for OPENCoastS deployments:� Açores Islands, PT

� Guanabara bay, Brasil

� Praia, Cape Verde

� Falmouth, UK

• Providing tailored-to-need servicessupported by OPENCoastS: emergency, coastal management, research, teaching, leisure…

Atlantic-wide application in the scope of theAIR Centre implementation

The AIR Centre framework will provide several opportunities:

1. To extend the applicability of the service to the whole Atlantic Ocean, through collaborations and data/information exchanges with the AIR Centre partners

2. To provide further opportunities of collaboration in coastal services with the AIR Centre partners

Coastal margin observatories

Challenges for big data management from real-time model predictions and online + historic monitoring networks

Atlantic-wide application in the scope of theAIR Centre implementation

3. To scale up this service to other complex

challenges: water quality and ecosystem

dynamics (require more extensive

computational resources - AIR Centre

partners)

4. To create a standard for circulation

forecasting in Atlantic coastal waters that

can be tested and evaluated by all partners

in the AIR Centre community
