Aeolian Sediment Transport and Coastal Dune Evolution

As part of a scientific field experiment on wind and wave driven sediment transport on the Washington coast, we utilized a Dyacon weather station to provide relevant meteorological measurements. Despite the harsh conditions of the Washington coast, including high wind speeds and the corrosive effects of salt spray, the Dyacon system performed well throughout the year long study. Co-located measurements using an additional (much more expensive) competitor’s meteorological station also showed the Dyacon system has consistently reliable measurements – with the two datasets agreeing remarkably well. The Dyacon weather station far exceeded our expectations and it was a pleasure working with Eugene on this study!

“We at Papillon Airways, Inc. are very happy with the Dyacon weather station. It has delivered exactly what we were looking for. Our temperatures during the summer get so hot that we often have to discontinue our helicopter flights. By having the weather station at our landing site at the bottom of the Grand Canyon, we can see exactly how hot it is and also how fast the temperature is rising. This has greatly improved our ability to anticipate the need to stop operations. We have had fewer interruptions to our operations since installing the weather station.

We are very impressed with the reliability of the unit. Our Verizon coverage is very weak at the bottom of the Grand Canyon, however, we have only lost the signal once this year and that was due to a Verizon failure. All in all this has been a very good investment. Papillon highly recommends the Dyacon Weather Station and their superb support.”

In blueberries crop, under specific meteorological conditions, it is common B.cinerea sp attack the flowering and also fruit set, affecting economical results at the end of the harvest season.
The most common condition to fungus development is a combination of meteorological factors.

  1. Temperature below 15C
  2. Relative humidity between 92% to 100%

Sensors like TPH1 or TPH2 (Dyacon Inc.) measure this environmental factors very accurate.[sic]
We can estimate Growing Degree Days in combination with Deficit Vapor Pressure to predict fungus development.
Early alarm (above a threshold) of fungus development will help us to improve chemical applications.

Some features to highlight:

  • TPH1 and TPH2 easy to connect to third party dataloggers ( SDI-12 or RS485 protocol).
  • Very Low power
  • Accuracy
  • Perfect cross arm to mount in a pole
  • Multiple applications
  • Plug and play

“For the last 4 years we have been using Eugene’s system with text message access with great success.  The equipment is very reliable, provides a timely and accurate transmission of important airport weather.  We have had several pilots use the weather data while in-flight to determine if they needed to divert because of unfavorable or high winds from many miles away. 

At our small airport we have been able to decrease aircraft over flights to check winds which also helps us decrease operational noise signatures because pilots can check winds similar to a Metar report at a fraction of the cost.”
