Modelling of Crop Reference Evapotranspiration: A Review

Efficient irrigation water management requires a good quantification of evapotranspiration. The precise estimation of water requirement of crop is very important factor in the application of irrigation design and scheduling. Water relation model are essential component of all crop model because of critical role of water status has in determining growth, productivity and produce quality. Irrigat...

Spatiotemporal Variations of Reference Crop Evapotranspiration in Northern Xinjiang, China

To set up a reasonable crop irrigation system in the context of global climate change in Northern Xinjiang, China, reference crop evapotranspiration (ET0) was analyzed by means of spatiotemporal variations. The ET0 values from 1962 to 2010 were calculated by Penman-Monteith formula, based on meteorological data of 22 meteorological observation stations in the study area. The spatiotemporal vari...

Estimation Of Reference Crop Evapotranspiration Using Fuzzy State Models

Daily evapotranspiration (ET) rates are needed for irrigation scheduling. Owing to the difficulty of obtaining accurate field measurements, ET rates are commonly estimated from weather parameters. A few empirical or semi–empirical methods have been developed for assessing daily reference crop ET, which is converted to actual crop ET using crop coefficients. The FAO Penman–Monteith method, which...

A Threshold Denoising Method Based on Emd

The denoising method based on empirical mode decomposition (EMD) can be broadly divided into: IMF extraction method and IMF threshold approach. Aiming to the problems of how to select IMFs in extraction method and the processing of the selected IMFs, a threshold denoising method based on EMD is put forward. In this method, the standard of IMF selection in energy viewpoint is offered, and the IM...

Monitoring Cotton Crop Evapotranspiration Based On Satellite Data

The water demand to meet seasonal and long-term water needs in Thessaly, central Greece, is related to historical semi-arid conditions in the region, which is the main agricultural area of the country. In this paper irrigation water requirements are assessed through the estimation and monitoring of crop evapotranspiration ETc for cotton fields in Thessaly. Remotely sensed data are used to delin...
