UCCE Frost Protection Training Units
The two websites below contain narrated training units in a variety of important frost protection topics. These narrated presentations are also available in Spanish. All of these presentations are viewable online in Flash format; you will need audio on your computer to hear the narration.
UC Davis Biometeorology Program Frost Protection Website

Other Frost Protection Resources
Dr. Robert Evans, Supervisory Agricultural Engineer with the USDA-ARS, has written these comprehensive summaries of frost protection science and practice:
Temperature inversion information
The instruction sheet below provides information on how to assemble and install the 35 foot towers that are useful for assessing the temperature inversion conditions at individual sites. These are relatively inexpensive and highly portable, but are not intended for permanent or long-term use.
The December 2011 Grape Notes newsletter provides a detailed example of how the data from these towers can be used to measure inversion conditions and assessing the suitability of wind machines for frost protection.
