Introduction
I Meteorological data is mainly obtained from forecasting andobservation.
I Forecasting models provide information on the state of theatmosphere in the future...
I ... which has to be validated using data from observationsystems:
I Weather station networks, hail sensors, disdrometers, radiosondes,radar and satellites
Problems
I Researchers need data in order to contrast their hypothese.I The spatial and temporal heterogeneity of the data obtained.
Objetive
To develop a data repository with information from as many sourcesas possible that is available to anyone without restriction.

Research applications
1. Hail PrecipitationEvaluation Application
Weather radar image
Hail estimation using the APG’s hail probability algorithm.
2. Satellite Precipitation Evaluation Application
Precipitation intensity estimate using the MPE algorithm between 14.00 hrs and 23.00 hrs UTC on 1 May, 2014.The areas shaded in blue show the zones with a precipitation intensity of more than 1mm/h.
MPE algorithm evaluation using data from GFA Open Data. Areas in red correspond to hits by the algorithm,areas in blue are false alarms, and areas in green are lost cases.
Rainfall in Castile-León between 14.00 hrs and 23.00 hrs UTC on 1 st May, 2014. Areas shaded in blue showsthe zones with a precipitation intensity of more than 1mm/h.

Conclusions
I GFA Open Data has proved to be a powerful tool to support thework of researchers, and the APG has used it successfully in itsresearch projects:
1. Hail Precipitation Evaluation.2. Satellite Precipitation Evaluation.3. WRF precipitation evaluation.
I GFA Open Data also has a high potential for as a support tool forteaching meteorology:
I The three applications mentioned above allow us to make ameteorological data analysis from GFA Open Data information forteaching purposes.
I They also makes it easier to evaluate students’ knowledgeacquisition and to analyse global results.
