Error propagation approach for estimating root mean square error of the reference evapotranspiration when estimated with alternative data
Autor: Homayoon Ganji, Takamitsu Kajisa
Publikováno v: Journal of Agricultural Engineering, Vol 50, Iss 3 (2019)
Estimation of reference evapotranspiration (ET0) with the Food and Agricultural Organisation (FAO) Penman-Monteith model requires temperature, relative humidity, solar radiation, and wind speed data. The lack of availability of the complete data set

DEVELOPMENT OF PADDY-FIELD WATER LEVEL GAGE CORRESPONDING TO A SENSOR-NETWORK
Autor: Takamitsu Kajisa, Ryoei Ito
Publikováno v: INMATEH Agricultural Engineering. :131-136
This study proposes a measurement system that comprises an e-Tape water level sensor, Arduino and XBee. The system was considered a success because of the linear relation between measured voltage signals and water depths obtained by it. This linearit

The Penman-Monteith model with alternative and measured data in three regions of Afghanistan (Central-North- East) was discussed by estimating reference evapotranspiration (ET0). The result showed that in the high rate of ET0, the difference between

Impact of Alternative Data on the Penman-Monteith Method Considering Windy Conditions in the Semi-Arid Area
Autor: Takamitsu Kajisa, Homayoon Ganji
Publikováno v: American Journal of Water Resources. 6:217-223
When real data are unavailable, the standard Penman-Monteith method for estimating reference evapotranspiration can be calculated using alternative input data: wind speed from a nearby station, the default global average wind speed, solar radiation b

Determining the Effective Distance Spatially for Sharing the Climatic Data Relating to Reference Evapotranspiration
Autor: Takamitsu Kajisa, Homayoon Ganji
Publikováno v: American Journal of Water Resources. 6:212-216
The estimation of reference evapotranspiration (ET0) with the FAO-Penman-Monteith method faces challenges in some places due to its high data demand. To overcome this challenge some methodologies recommended by FAO. However, sharing the nearby statio
