Estimation of thermodynamic parameters of the biosphere, based on remote sensing

Assessing the thermodynamic variables of landscapes in the southwest part of East European plain in Russia using the MODIS multispectral band measurements

“…In the winter, the minimal entropy is observed for a snow cover of steppes and mires, and maximal-for spruce forests. During the transitional spring and autumn periods, the entropy in general maximal values that corresponds to results obtained on the global scale for the northern hemisphere (Puzachenko et al, 2011). Thus, the maximal entropy is observed in the steppe, and the minimal ones-in coniferous forests.…”

“…It can be expected, that a possibility to estimate the spatial contrasts of exergy for different vegetation types in various seasons is able to create a base for development of mesoclimate models. Analysis of spatial and temporal variations of thermodynamic variables five us a new view on functioning of a landscape cover (Puzachenko et al, 2011;Puzachenko et al, 2013) and allow to reveal earlier not obvious features of transformation of solar energy by different landscape types.…”

Methods of Evaluating Thermodynamic Properties of Landscape Cover Using Multispectral Reflected Radiation Measurements by the Landsat Satellite

“…Examples of the calculation of thermodynamic variables based on multispectral images from Landsat TM and ETM+ were suggested by Jorgensen and Svirezhev [3] and further developed by Puzachenko and Sandlerskiy [4,7]. These studies also present the theoretical basis of interpreting the thermodynamic variables.…”

“…Jorgensen and Svirezhev [3] demonstrated a principal possibility of remotely measuring exergy (useful work) associated with heat and water exchange. The evaluation of seasonal changes of thermodynamic variables based on Modis data showed their high informational value for studying spatio-temporal variability of landscape cover at the global level [4]. In the current article, we demonstrate methods of evaluating thermodynamic variables using the Landsat satellite imagery and show how these methods could be applied to southern taiga communities of the Central Forest Biosphere Reserve (56°30' SL., 32°53' EL.…”

Thermodynamic Assessment of Chernozems Forest Reclamation

“…Распространяется он и на почвообразование. Так как гумус в этих исследованиях является основной характеристикой агрономической ценности почв, изучение энергетических характеристик гумуса и его количественных составляющих встречается в последнее время довольно часто, что свидетельствует о значимости этого показателя, как геохимического аккумулятора энергии Солнца, содержащего n 1020 ккал энергии [12].…”
