Development of Agro-Meteorological Information Systems

1.农作物生产的农业气象信息分析与整理：1）以马铃薯为研究对象; 2）土壤温度和日照量是马铃薯生产的重要信息。土壤积温和太阳总辐射资料可提供有用的信息.地形小气候的定量化及局地气象信息的采集方法：1）收集局地气象信息的有效方法有两种：a）红外测温仪资料与地面数值资料相结合的方法; B）利用电话线和无线电话的野外数据采集系统; 2）探讨利用气象雷达获取局地降水信息的可能性; 3）利用气象雷达获取雨量基础资料。然后我们做了一些 ...更多信息 4）在收集当地实际气象资料时，必须对当地的气象现象和气候有正确的认识.利用卫星资料和网格资料的方法：1）利用卫星资料估算地表温度; 2）利用地面温度估算值与AMeDAS资料气温之间的相关关系，估算无气象观测站地区的气温; 4）利用网格资料时，应充分把握以下误差：a）第一误差发生在制作数据时; B）第二误差发生在插值估算网格点外其他点的值时。农业气象信息系统的现状分析和需要解决的问题：（1）对农业气象有关机构进行了问卷调查。（2）问卷调查结果表明，农业气象信息系统在日本大部分地区得到了实际应用。（3）农业气象信息系统存在的问题是：（1）系统费用高;（B）预报精度不够高;（3）能够使用该系统的人才不足;（4）信息种类不够多。少

1. Analysis and arrange of agrometeorological information to produce crops :1) The potato is selected as the objective crop for study.2) The soil temperature and the amount of insolation are important informations to produce potato. The air temperature can be substituted for the soil temperature.3) Data of cumulative soil temperature and total integrated solar radiation fre useful informations.2. Quantify of topography concerned microclimate and method to collect local meteorological informations :1) Two effective methods to collect local meteorological informations are as follows.a) The first method is the infrared thermometer data combined with the numerical terrestial data.b) The second method is the field data acquisition system using telephone line and wireless telephone.2) We examined the possibility to use the meteological radar for getting the information of rainfall in the local area.3) Using the meteological radar, we collected the basic data of rainfall. And, we made out som … More e problems concerning estimation of rainfall.4) On collecting the practical local meteorological informations, it is necessary to have a right understanding of the local meteorological phenomena and the local climate.3. Method to use satellite data and mesh data :1) The ground surface temperature is estimated on the satellite data.2) The correlation is found from the estimated ground surface temperature and the air temperature of AMeDAS data.3) The air temperature in the area without meteorological observing station can be estimated on this correlation.4) In using mesh data, it is necessary to grasp thoroughly following errors.a) First error occurs when we make data.b) Second error occurs when we estimate the value on other point out of grid point by interpolation.4. Analyses of the present condition of the system of agrometeorological information and problems to be solved :1) The questionnaire was conducted on the organs concerned with agrometeorology.2) The result of this questionnaire said that the system of agrometeorological information is put to practical use in almost parts of Japan.3) The problems of this system are as follows.a) This system requires great expense.b) The accuracy of forecast is not good enough.c) The number of capable men who can use this system is not good enough.d) The number of types of information is not good enough.
