This is a map-based interface allowing one to access various climate data for any 4km x 4km grid-cell in the contiguous 48 states.  It offers the ability to retrieve the dates of the last 28F and the last 32F in the Spring and the first 32F and first 28F in the Fall for each year from 1960 - 2001 (soon through 2006).
