Air temperature is a key variable in wide range of environmental applications, including land–atmosphere interaction, climate change research and hydrology crop growth models, among others. The objective this study was to estimate daily maximum (Tmax) minimum (Tmin) temperatures, based on MODIS AQUA/TERRA land surface (LST), NDVI, extraterrestrial solar radiation precipitation data. Artificial ...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
Recent warming significantly advanced leaf onset in the northern hemisphere. This signal cannot be accurately reproduced by current models parameterized by daily mean temperature (T(mean)). Here using in situ observations of leaf unfolding dates (LUDs) in Europe and the United States, we show that the interannual anomalies of LUD during 1982-2011 are triggered by daytime (Tmax) more than by nig...
abstract the present study is attempted to present the minimum required meteorological parameters for reference evapotranspiration estimation at hamedan region of iran from 1997 to 1998. employing pierson test, six meteorological parameters which are used by penman-montieth fao-56 method including maximum and minimum air temperature, maximum and minimum relative humidity, wind speed and daily s...
Frequency, duration, and intensity of hot-weather events are all predicted to increase with climate warming. Despite this, mechanisms by which temperature increases affect individual fitness and drive population-level changes are poorly understood. We investigated the link between daily maximum air temperature (tmax) and breeding success of Kalahari common fiscals (Lanius collaris) in terms of ...
Since the 1950s, East Asian diurnal temperature range (DTR), defined as difference between daily maximum (Tmax) and minimum temperatures (Tmin), has gradually decreased. Precipitation changes have often been cited a primary cause of change. However, DTR change before 1950 its relationship with precipitation remain unclear. Here, we used newly developed China Meteorological Administration-Land S...
Agricultural research increasingly is expected to provide precise, quantitative information with an explicit geographic coverage. Limited availability of daily meteorological records often constrains efforts to provide such information through use of simulation models, spatial analysis, and related decision support tools. The Prediction Of Worldwide Energy Resources (NASA/POWER) project at the ...
