Project Description:

The goal of this GIS project is to produce distribution maps of average maximum daily temperature achieved for 3, 4, and 5 consecutive days in the San Joaquin Valley to be used for mitigation decisions. These temperature threshold maps are provided in an interactive website with other important map layers such as roads, Township, Range and Section lines, field boundaries, and locations of olive orchards so that growers and researchers can navigate to an area of interest. Once a specific area is viewed, the underlying climate map symbology indicates the potential in the last ten years for high temperatures to be reach for several consecutive days, thereby likely causing olive fly death. Further, the last five days of maximum temperature from the CIMIS network are provided for each station and these values can be viewed by clicking on a neighboring CIMIS station point. It is proposed that providing maps of the climatic probability of high max. temperature for several days in a row, and the last several days of real-time high temperature values, a grower can make a decision about applying chemical abatement or not.
