The invention relates to a system for providing a site-related weather insurance contract for a product, such as an agricultural product like seeds or fertilizer. The system comprises a central data processing unit (CDPU), a remote measurement device (RMD) for the measurement of site-dependent weather parameters, and a remote data processing unit (RDPU) of a retailer. The RMD measures and provides the site-dependent weather parameters as remotely measured data. The RMD communicates the remotely measured data to a CDPU. The RDPU generates a data set (RDPU data) an insurance ID code and communicates the RDPU data to a CDPU. The CDPU receives the RDPU data and generates an individual contract confirmation code and communicates it to at least one remote communication device (UCD). The invention further relates to a method and a retailer remote communication device (RRCD), computer software, and a data storage medium, each usable with the system.
