kn-abstract=We have developed a minimum air temperature forecasting system using local meteorological
observation data in order to prevent or mitigate the frost damage. In this paper, the correlation between the meteorological factors and the decrease in air temperature during the night was shown. Then minimum air temperature was predicted by the multiple regression equation that uses air temperature and humidity at 18:00 as explanatory variables. As the result, the root mean square error (RMSE) was 2.8°C. When the difference of air temperature between 17:00 and 18:00 was used for the prediction instead of humidity, the RMSE was 3.5°C. Next, the prediction was carried out only in clear nights, then the equation that use air temperature and humidity at 18:00 showed that the RMSE was 1.3°C. Although the predictive accuracy of the equations for clear nights is low on cloudy or rainy nights, we can forecast safely on frosty nights by using those equations in combination with the equations for all nights.

kn-abstract=　The purpose of this study is to build a forecast system for predicting at minimum air
temperature in the next morning from the meteorological data, such as air temperature,
humidity, and the amount of solar radiation, in a field in the evening on the previous day. The
meteorological data are sent to a relay server, and then, transferred to a PC in our laboratory
of Okayama University by executing the computer program to import the data which are used
to calculate the predicted values of minimum air temperature. The predicted minimum air
temperatures are released for the farmers on the website in the server of Okayama University.
The website is also created by our laboratory. As a result, the predicted minimum air
temperatures agreed with the measured ones.

kn-abstract=Advection-Aridity(AA) model can calculate actual evapotranspiration by using only meteorological data. However, comparing the model with Penman equation showed that AA model doesn’t properly evaluate evapotranspiration from urban moisture area. In urban area, Actual evaporation from water calculated by AA model(E) are much less than that by Penman equation(Epo). Multiple regression analysis using estimation results indicates that the difference between the models is due to the difference of the sensitivity to vapor pressure deficit between the models. To improve this problem, modification coefficient k, defined as k=a･albedo+b, is suggested. Regression coefficients a, b are determined as satisfying k=Epo/E for water and k=1 for urban surface. By using this coefficient k, evaporation from water is nearly equal to value estimated by Penman equation, while evaporation from urban surface is changeless.

kn-abstract=It is very important to measure the water content and electric conductivity in soil for monitoring the environment of agricultural land continuously. TDR (Time Domain Reflectometry)method plays a key role on the
measurement of water content and electric conductivity in soils recently. Some calibrations are needed to measure them accurately. The objective of this study was to investigate preliminaly the corrections of TDR probe, the probe constant for electric conductivity, and the dependence of water pemittivity on temperature as TDR calibrations. The results showed the importance for the corrections of TDR probe and the reasonable value of probe constant.The TDR system used in this study could measure the dependence of water pemittivity on temperature.

kn-abstract=Subsurface contamination by non-aqueous phase liquid (NAPL) has become a serious environmental issue. Therefore, it is necessary to estimate the NAPL content (θNAPL) in unsaturated soil to detect and monitor the NAPL contaminations in soil and groundwater. The objective of this study was to investigate the relationship between θNAPL and permittivity (K) in unsaturated sandy soil as a fundamental study to estimate the θNAPL. An ADR (Amplitude Domain Reflectometry) method was used to measure the K in the soil including the NAPL which was a castor oil as light NAPL or a HFE-7100 as dense NAPL. The experimental study indicated the linear relation between θNAPL and K in unsaturated soil with soil-NAPL-air. Using this relationship, we can estimate the θNAPL. On the other hand, although we obtained the relationship between θNAPL, θw and (root) K in unsaturated soil with soil-NAPL-water-air, it was not possible to estimate the θNAPL using this relationship.

The typical results were as follows: (1) The increasing rate of the annual mean air temperature was 1.07℃/111 year. (2) The increasing rate of the monthly minimum air temperature was larger than that of the monthly maximum air temperature. (3) The increasing rate of the monthly air temperature was large from winter to spring, however, was not so from summer to autumn. (4) The decreasing rate of annual precipitation was 0.187 mm/year. (5) The 5-year moving average of annual snowfall-depth might indicate the existence of about 10-year period.

The system of measurement consists of DC power supply, data logger, personal computer, 100cc soil sample, reference material sample, and two heat probes. The typical results were as follows: (1) Thermal conductivity of soils increased according to an increase of soil water content. (2) The thermal conductivity of Toyoura sand was larger than one of Kuroboku soil. (3) The thermal conductivity estimated by de Vries model had good agreement with the measured value.

kn-abstract=Thermal conductivity of soils in Shirakami Mountains that was registered on UNESCO's World Natural Heritage in 1993 were measured using a twin transient-state cylindrical-probe method. The typical results were as follows:(1) Thermal conductivity of the soils in Shirakami Mountains increased according to an increase of soil water content, which was the same tendency as the other soils. (2) The thermal conductivity of the soils was about 0.2〜0.3 Wm(-1)K(-1) smaller than volcanic ash soils, and it showed the same tendency as leaf mold.
