Development of Variable Threshold Models for detection of irrigated paddy rice fields and irrigation timing in heterogeneous land cover

Jeong, S.; Kang, S.; Jang, K.; Lee, H.; Hong, S.; Ko, D. - In: Agricultural Water Management 115 (2012) C, pp. 83-91

Accurate monitoring of irrigated paddy field area and irrigation timing are of a great concern in agricultural water management due to the substantial consumption of fresh water when irrigating paddy fields. Spectral threshold methods (Xiao et al., 2005) have been widely applied to detect...

A model for calculating global illuminance from satellite data

Janjai, S; Jantarach, T; Laksanaboonsong, J - In: Renewable Energy 28 (2003) 15, pp. 2355-2365

A model for calculating global illuminance on horizontal surfaces from meteorological satellite data was developed. The … illuminance were calculated. These values were used to correlate with those of cloud index derived from the satellite data. From …

Low-dimensional dynamical system model for observed coherent structures in ocean satellite data

López, Cristóbal; Hernández-Garcı́a, Emilio - In: Physica A: Statistical Mechanics and its Applications 328 (2003) 1, pp. 233-250

The dynamics of coherent structures present in real-world environmental data is analyzed. The method developed in this paper combines the power of the Proper Orthogonal Decomposition (POD) technique to identify these coherent structures in experimental data sets, and its optimality in providing...
