The occurrence of frost injury in microclimatic (4) areas much, later in the spring and earlier in the fall than seemed possible from an examination of Weather Bureau records has been noted many times by a number of investigators (1, 3, 6). Quantitative temperature and growth data have been presented for microclimatic areas of varied topography in southern Iowa which showed a close relationship between reduction in temperature in the early spring of 1942 and the degree of frost injury in the grape (1, 2).
