wall climate layers at a high enough resolution to inform decision-making at a field level. 3. To present these climate surfaces as an easy-to-use online mapping tool, the TerraClim website, which allows users to view, query and draw reports of environmental and climatic variables at a field or farm level. Supporting this, the TerraClim project has a strong climate research and development (R&D) component. One task is to make use of multi-criteria analyses to identify areas where the extension of the existing weather station network should be prioritised. Building and updating a long-term and semi-real-time climate database is another important R&D activity. The database will allow for dynamic mapping, statistical interrogation, data mining, machine learning and climate change analyses over time. Additionally, TerraClim both depends on and supports other platforms in the agriculture sector, sharing information across platforms to ensure that researchers, consultants and farmers have access to the best resources for informed decision-making. HOW TO MAKE INFORMED DECISIONS USING TERRACLIM TerraClim has been designed with different

agricultural stakeholders in mind, and it is hoped that the platform will be beneficial to winemakers, land owners, farm managers, consultants and researchers alike. The technology is easy to use and requires only a personal device with internet connectivity. Anyone who has used Cape Farm Mapper or Google Earth will be familiar with the web-mapping format, where a user can geographically navigate to a location of choice and then select the specific data they wish to view. Users can also click on specific FIGURE 3. Hourly temperature maps for a 24 hour cycle to identify the temperature dynamics of a specific area and to contextualise this information on a seasonal or multiyear basis.
