Supply of meteorological data for MARS project

The European Commission's Joint Research Centre (JRC) has published an invitation to tender for the supply of quality-checked meteorological data for the Monitoring of Agriculture by Remote Sensing (MARS) project.

The MARS project is managed by the Agricultural Information System Unit (AIS), of the JRC's Space Applications Institute, and uses daily meteorological data for input to agro-meteorological models. Since 1991 a contractor receives meteorological data from the Global Telecommunication System (GTS) network, pre-processes, quality checks and supplies them to the MARS project on a daily basis via Internet. The MARS project has already gathered an archive of harmonized meteorological data from a network of stations across Western and Eastern Europe, the former USSR, Maghreb and Turkey. The present call for tenders is for the continuation of the existing contract for the supply of data.

Data must be acquired by the suppliers on a daily basis from the GTS data network. The zones of interest are: Western and Eastern Europe, the former USSR, the Maghreb countries and Turkey. Stations to be considered are across all the zones of interest, with about 2,400 meteorological stations currently considered in the system. For each country, a minimum number of equally distributed meteorological stations will be specified in the tender documentation. Data must be pre-processed (decoded, checked and interpolated to fill missing values) using AMDAC, the meteorological data decoding, filing and quality evaluation software. This package is the property of the MARS project.

AMDAC flags questionable data values for subsequent verification. The process of reviewing the output of AMDAC and checking the observed values must be undertaken by a trained meteorologist working in an environment where there is access to additional information (such as analysed observation maps) which may serve as the basis of confirmation or rejection of the observed values. AMDAC must be run every day, seven days a week. The maximum delay between raw data reception by the supplier and delivery of processed data to the MARS project should not exceed three calendar days.

The data to be purchased will cover the period from July 1997 to May 2000, based on yearly phases.
