An iterative method for deducing the general temperature and moisture structure of the troposphere from satellite radiation measurements of medium spectral resolution is described. The temperature and moisture profiles derived from simulated and radiometrically observed radiances, pertaining t o clear atmospheres, are shown to agree favorably with the radiosonde profiles. The method is expanded...

The objective of this work was to explain an apparent contradiction in the literature related to the relationship between mean and variance (or standard deviation) of soil moisture fields. Some studies found an increase in soil moisture variance with decreasing mean soil moisture, while others showed a decrease. The evidence of maximum variance in the mid-range of mean soil moisture was also re...

A large amount of oyster mushrooms is wasted every year due to post-harvest losses/decays. An experiment was conducted to observe the effect of low temperature to extend shelf life and nutritional quality of oyster mushroom. The experiment consisted of two treatments including: mushrooms stored at ambient (25 °C) temperature or stored at 3 °C temperature. The experiment wa...

abstract using mathematical models for irrigation management have great impacts to increase irrigation efficiency and product amount, in fields. in this study, simulation results by swap model for moisture, compared with soil profiles moisture values, measured in the field. moisture data, measured at three wheat farms in the neyshabur plain, were used to predict moisture. results show good agre...

dust is a common atmospheric phenomenon in iran especially in central arid regions.  this severely affects environment as well as resident’s health. among the results of this phenomenon are respiratory diseases, bash radiation, accelerated soil erosion, desertification and degradation of ecosystems. some dusts are originated from local desert conditions but adjacency to neighboring countries de...

This paper reports on the comparison of surface temperature and soil moisture observed by instruments onboard the Environmental Satellite (EnviSat) with simulations by an atmospheric circulation model over the period April 2005 to September 2007. The Naqu river basin has been selected as the study area, which is located on the eastern part of Tibetan Plateau. For the selected period, the PSU/NC...

The temperature sensitivity (Q10) of soil heterotrophic respiration (Rh) is an important ecological model parameter and may vary with temperature and moisture. While Q10 generally decreases with increasing temperature, the moisture effects on Q10 have been controversial. To address this, we conducted a 90-day laboratory incubation experiment using a subtropical forest soil with a full factorial...

UNLABELLED BACKGROUND AND AIMS The negative logarithmic relationship between orthodox seed longevity and moisture content in hermetic storage is subject to a low-moisture-content limit (m(c)), but is m(c) affected by temperature? METHODS Red clover (Trifolium pratense) and alfalfa (Medicago sativa) seeds were stored hermetically at 12 moisture contents (2-15 %) and five temperatures (-20, 30,...
