Temperature-based CME® Weather products - Heating, Cooling, Cumulative Average Temperature and Seasonal strip contracts - continue to show tremendous growth. Their success has generated interest in additional types of products designed to meet the unique risk management needs of various locations and cities.

In response to the marketplace's request for more customized weather products, CME offers futures and options on Frost Days for Amsterdam-Schiphol, Netherlands (WMO 06240). These contracts launched on September 23, 2005.

How to Calculate CME Frost Days
Calculating frost days for CME Frost Day futures involves recording temperatures twice a day, early morning and mid-morning, during the work week, but not on Saturdays, Sundays or the winter holidays: December 25, 26 and 31. Temperatures are recorded from the beginning of November through the end of March in terms of their distance from Celsius within a range of -0.5 to -3.5 degrees Celsius. A Frost Days Index, compiled and maintained by Earth Satellite Corporation, is used for settling these contracts.
