European Convection Forecast 1.0
Current JSON

Abstract

Convection forecast product using a multimodel approach and delivered as a WFS (GeoJSON) SWIM webservice. 

Thunderstorms are a major cause of disruption of Air Traffic Management network. Convection forecast is designed to support Flight Management operations and Air Traffic Flow and Capacity Management process.

The multimodel algorithm integrates different parameters coming from different weather models (DWD, MétéoFrance,  NOAA) that can indicate the probability of thunderstorms.

A weighting is applied to each parameter and model then the whole is assimilated to provide a homogeneous output including a confidence index parameter.

 

Convection forecast characteristics are:

- +24H forecast by 1 hour step

- 10km geographical resolution over Europe

- Refresh every time a model is updated (average of 9 updates/day)

- Delivery as convective cells with a severity level and a confidence index.

- Ensured quality of service through Service Level Agreement

 

This innovative product has been tested and validated during summer 2020 in the context of SESAR ENGAGE project MET ENHANCED ATFCM.

MetSafe proposes an access to global meteorological webservices for the aviation community through its cloud-based services platform. 

Access to data service delivers on a global scale regulated meteorological products, real time adverse weather service (radar, satellite) and numerical weather prediction products.

State of the atmosphere services (wind sand, SO2…) are also proposed based on COPERNICUS data.

Information is delivered through a SWIM yellow profile compliant API with ATM-grade quality of service.

MetSafe platform is powered by multiple meteorological sources. A partnership with MétéoFrance and Météorage ensures access to the latest state of art meteorological products.

Beyond provision of access to data, MetSafe provides tailored expert services such as extraction of meteorological information around the 4D trajectory or weather impact prediction for ATFCM.

Our meteorological webservices are used operationally to support various applications: Air Traffic Control Working position, Electronic flight Bag, fuel optimisation for airline.

MetSafe is based in ENAC Incubator, Toulouse.

GET european convection forecast

This service allows to retrieve +24H convection forecast over a bounding box. It uses WFS as a service layer, WFS filtering capabilities are available.



 

Authentication

Access to MetSafe services requires an access token that connects API requests to your account. See customer onboarding below for access to Convection Forecast Service.

Operational Policy

The convection forecast service provides information based on probabilistic information. Convection forecast contains uncertainties. This service shall not be used for safety-critical decision. 

Availability

Convection forecast is delivered from a European-wide cloud infrastructure ensuring resilience. The service is provided with an ATM-grade quality of service.

The default guaranteed service availability by SLA is 99,5%.

Response time

The default response time is < 5s for 95% of requests, <10s for 99% of requests.

Integrity

Integrity is ensured through quality check.

Common UTC source

MetSafe platform is synchronized to UTC source. The systems consuming the service shall be synchronised to a UTC time-source.

COLLABORATIVE_VALIDATION
Validation

MetSafe, DSNA and France Aviation Civile Services teamed up in 2019 to speed up innovation in the ATC room. Delivery of convection forecast in the ATC room was the objective of the SESAR ENGAGE 'MET enhanced ATFCM' project.

Operational validation in the ATC room has been performed starting summer 2020: 16 FMP operators were trained on VigiAero and provided daily operational feedbacks.

Through operational validation in the ATC room, the convection forecast was validated for weather awareness and reached the objective of delivering actionable data for FMP.
