Measurement instruments 



A Yellow Springs Instrument Company, Inc. (YSI) (Yellow Springs, OH), electronic temperature 

 probe with analog output interfaced to the FRF's computer was operated beside the NWS's meteoro- 

 logical instrument shelter located 43 m behind the dune (Figure 2). To ensure proper temperature 

 readings, the probe was installed 3 m above ground inside a "coolie hat" to shade it from direct sun, 

 yet provide proper ventilation.
