Coming soon: extended TerraClim extent!
Development is currently underway to extend TerraClim to cover 98% of wine vineyards in the Western Cape. The first few layers will be available from December 2020
Creating climate layers at such a high resolution (40m or greater) requires dividing and processing the area as subregions, as seen in the map below. For more information on the research behind this, please see our Story Map
