In the present study, remote sensing of soil moisture is carried out using the Passive and Active Land S-band airborne sensor (PALS). The data in this paper were taken from 5 days of overflights near Chickasha, Oklahoma during the 1999 Southern Great Plains (SGP) experiment. Presently, we analyze the collected data to understand the relationships between the observed signals (radiometer brightn...

Characteristics of reflection spectrum, multi-spectral images and temperature of lettuce canopy were gained to judge the lettuce’s water stress condition which could lead to a precise, rapid & stable test of lettuce moisture and enlarged the models’ universality. By the extraction of lettuce’s multisensor characteristics in 4 different levels, quantitative analysis model of spectrum including 4...

69 m7 The European Space Agency (ESA) will launch the Soil Moisture and Ocean Salinity (SMOS) mission in late 2009. This mission is aimed at monitoring, globally, surface soil moisture and sea surface salinity from radiometric L-band observations [1]. Soil moisture is a critical state variable of the terrestrial water cycle and the factor that links the global water, energy and carbon cycles. C...

The potential of the ERS-1/2 scatterometer global soil moisture product has been shown in several studies. The ASCAT sensor on-board the METOP satellite is extending the 16 year time series of the ERS-1/2 scatterometer as a source for extracting information for ocean and land applications. Calibrated ASCAT data will continue the scatterometer global soil moisture archive while improving both th...

It is important to monitor the moisture content of transformer oil in a transformer. One parameter of particular interest is the moisture solubility of transformer oil. It has been reported that transformer oils under different conditions have different solubility. Measurements of solubility for four different types of conditioned oil are presented in this paper: fresh Shell Diala AX oil, lab-a...

in order to evaluate the effects of drought stress and methanol foliar application on some quantitative and qualitative traits of soybean (cv. viliamz), a split plot experiment was conducted based on randomized complete block design at the faculty of moghan research farm in 2011. treatments were three levels of drought stress based on irrigation at depletion of 40, 55 and 70 percent of availabl...

Addae-Mensah, Nda-Agyima K.. M.S.A.B.E., Purdue University, May 2014. Quality Changes in Hermetic Stored Corn caused by Fungi and Sitophilus zeamais (Motschulsky). Major Professors: Klein Ileleji and Linda Mason. Hermetic storage has been shown to be effective in controlling insect pests and maintaining grain quality of dry grains at 13% moisture and below. However, the feasibility and use of h...
