Corn GDD in Fargo, ND increased 33.5
heat units per decade since 1890
There are 335 additional heat units available today for corn development
compared to 100 years ago.
That is 16% of total heat units
necessary to mature a corn plant
in Fargo.

2 Trace Events in 2010
Manual Procedure1.Count number of un-measurable snowfall events
(Trace) among the months that had no measurable snow events.
2.Give higher ranking for the months that produced the least number of “Trace” events

Ranking After the ManualProcedure
Automated ProcedureWe developed a proper tie-breaker procedure:
1. to minimize climatic ties, and2. to properly identify an extreme precipitation event
in a dataset where the record event may seem to be hidden among the other events sharing the same magnitude before the traces are properly evaluated.
MethodAssign “T” a numerical value such that it
a. Would not change the magnitude of the precipitation
b. Would only help automate manual procedure to incorporate “T” events into ranking calculations
T=10−5
