Work pakage 2 - Joint module development - MEDUSA

WP leader: HYDS

Partners involved: HYDS, DLR


Objectives

O2.1 Implementation of the components of the system incorporating the modules developed in the scientific part.


O2.2 Verification of the system in real time.


O2.3 Support in evaluations for final experiment at airports of Munich  and/or Frankfurt.


Tasks:

T2.1 Data acquisition module.

Development of the data acquisition module (system of data readers, conversion to standards, etc.). This component will be devoted to the real-time acquisition of the different data source required by the system.

T2.2 Data base design and development.

This component will contain the whole information used by the system. The objective is to design and develop a solution that allows incorporating both the static and the dynamic data required by the system. The following major tasks are foreseen:

•Homogenize the metadata representation by means of ISO standards.

•Explore the utilization of self-descriptive formats oriented to store raster information.

•Define a database architecture that allows for the storing of the information required by the system.

•Development of a generic engine to read raster data, and oriented to hydrometeorological data (radar, satellite, model outputs, etc.) which will allow to convert real time acquired data to the selected standards (NETCDF, HDF).

T2.3 Data base services development.

A number of services related to the database will be developed that will allow to provide information and contents to the different ‘users’ of the system. The concept of users embraces front-end clients of the system (that will have access to specific contents) to any algorithm or module that requires data or information to compute a simulation, derive a product, provide a warning, etc. Previous to the development of the Web Services a detailed analysis of requirements from all standard users will be carried out.

T2.4 Implementation and integration.

Implementation at DLR of database and services. Integration of DLR/HYDS meteorological modules. The integration will make intensive use of the different previously developed services, especially those focused on the encapsulation of the meteorological modules: activation of processes of data selection, activation of models and managing of their output, etc. The integration will permit the user to activate/generate contents both off-line and on demand. Additionally it will be possible to produce generic products/contents by means of the activation or concatenation of the services developed. This framework will come out as a key piece of the system as it will play the role of the ‘factory’ for the different generated products (products, modeled data, warning, animations, etc.).

T2.5 Development of the Ajax engine.

The chain of technologies enclosed under AJAX (Asyncronous Javascript + XML) has opened the possibility of developing Web applications with high degrees of interaction. In this context the objective in the development of MEDUSA will be to investigate and develop, using AJAX technologies, a library of javascript elements that define the functioning and interactions of the MEDUSA Web component with the server in order to provide the meteorological contents generated by the system.

T2.6 Implementation at DLR of the Ajax Engine.

Integration with previous work, design and development of prototypes for displaying data of typical users.

T2.7 Testing of MEDUSA for case studies/sites.

The develop system will be tested using data from experiments 1 and 2 at MUNICH.
