[AAS13-04] Multi-point meteorological observation for Cross-country skiing
Keywords:Multi-point observation, Cross-country skiing, Wax, XBee, snowpack
To compensate for the drawback, the simulation softwares have been used to estimate the snow temperature on the course; the idea has been adopted in a foreign national team. Since it has been estimated from meteorological measurements at very limited position, it is unclear whether the simulated data is consistent with the actual weather conditions. Thus, if we could analyze the weather based on multi-point observation, the wax can be scientifically selected and we can make the strategy of the race.
This study aims 1) multi-point meteorological observations, and 2) measurements of the coefficient of dynamic friction for cross-country skiing. In this study, we focused on 1).
We have developed a multi-point meteorological observation system which can record every minute, temperature, humidity, illuminance to judge whether it is sunny place or not, and wind speed which affect snow surface condition in actual cross-country skiing course (Hokkaido, Date-city). We made ~60 sets of the above sensors, and set up the observation system on the actual course. Observed meteorological data was recorded through the collection in a coordinator (Arduino) and through the sending by wireless communication (XBee pro). Next, we discuss the way to select optimal wax in comparison the actual meteorological data with the simulated using software (snowpack).
