Assessing monthly average solar radiation models: a comparative case study in Turkey
Sonmete, Mehmet H.; Ertekin, Can; Mengeş, Hakan O.; Hacıseferoğulları, Haydar; Evrendilek, Fatih (Springer, 2011)Solar radiation data are required by solar engineers, architects, agriculturists, and hydrologists for many applications such as solar heating, cooking, drying, and interior illumination of buildings. In order to achieve ... -
Assessing solar radiation models using multiple variables over Turkey
Evrendilek, Fatih; Ertekin, Can (Springer, 2008)Solar radiation drives many environmental processes; however, needs to be estimated indirectly from more commonly measured meteorological variables since these data are not readily available from most climate stations. A ... -
Emissions Of greenhouse gases from diesel consumption in agricultural production of Turkey
Aday, Beran; Ertekin, Can; Evrendilek, Fatih (European Center Sustainable Development, 2016)Agricultural sector is both energy consumer in the form of human labor, fossil fuels, electricity, seeds, fertilizer, and pesticides and energy producer in the form of food, feed, and biofuels. High agricultural use of ... -
Long-term spatiotemporal patterns of CH4 and N2O emissions from livestock and poultry production in Turkey
Külcü, Recep; Ekinci, Kamil; Evrendilek, Fatih; Ertekin, Can (Springer, 2010)This study quantified spatiotemporal patterns of CH4 and N2O emissions from livestock and poultry production in Turkey between 1961 and 2007. CH4(enteric) (from enteric fermentation), CH4(manure) (from manure management), ... -
Modeling potential distribution and carbon dynamics of natural terrestrial ecosystems : a case study of Turkey
Evrendilek, Fatih; Berberoğlu, Süha; Gülbeyaz, Önder; Ertekin, Can (Mdpi, 2007)We derived a simple model that relates the classification of biogeoclimate zones, (co) existence and fractional coverage of plant functional types (PFTs), and patterns of ecosystem carbon (C) stocks to long-term average ... -
Modeling spatio-temporal dynamics of optimum tilt angles for solar collectors in Turkey
Ertekin, Can; Evrendilek, Fatih; Külcü, Recep (Mdpi Ag, 2008)Quantifying spatial and temporal variations in optimal tilt angle of a solar collector relative to a horizontal position assists in maximizing its performance for energy collection depending on changes in time and space. ... -
Quantifying spatio-temporal dynamics of solar radiation exergy over Turkey
Alta, D.; Ertekin, Can; Evrendilek, Fatih (Pergamon-Elsevier Science Ltd, 2010)The insensitivity to energy quality is one of the disadvantages of an energy analysis when compared to an exergy analysis. It is only the exergy analysis that clearly reveals the degradation of energy quality in the processes ... -
Spatial viability analysis of grid-connected photovoltaic power systems for Turkey
Çağlayan, Nuri; Ertekin, Can; Evrendilek, Fatih (Elsevier Sci Ltd, 2014)This paper investigates viability of 0.2, 0.5, 1, 3, 5 and 10 MW grid-connected photovoltaic (PV) power plants using 22-year data for 135 locations across Turkey and RETScreen model to predict energy production. Mean annual ... -
Statistical modeling of spatio-temporal variability in monthly average daily solar radiation over Turkey
Evrendilek, Fatih; Ertekin, Can (Molecular Diversity Preservation Int, 2007)Though one of the most significant driving forces behind ecological processes such as biogeochemical cycles and energy flows, solar radiation data are limited or nonexistent by conventional ground-based measurements, and ... -
Techno-economic analysis of solar water heating systems in Turkey
Ertekin, Can; Külcü, Recep; Evrendilek, Fatih (Mdpi Ag, 2008)In this study, solar water heater was investigated using meteorological and geographical data of 129 sites over Turkey. Three different collector types were compared in terms of absorber material ( copper, galvanized sheet ... -
Total CO2-equivalent GHG emissions from agricultural human labour in Turkey
Adaya, Beran; Ertekin, Can; Evrendilek, Fatih (Italian Association of Chemical Engineering - AIDIC, 2017)Carbon dioxide (CO2) is one of the most important greenhouse gases (GHG) whose increased emissions have significantly enhanced greenhouse effect, thus changing global climate. To keep up with the rising growth rates of ... -
Using eddy covariance sensors to quantify carbon metabolism of peatlands: A case study in Turkey
Evrendilek, Fatih; Karakaya, Nusret; Aslan, Güler; Ertekin, Can (Mdpi Ag, 2011)Net ecosystem exchange (NEE) of carbon dioxide (CO2) was measured in a cool temperate peatland in northwestern Turkey on a continuous basis using eddy covariance (EC) sensors and multiple (non-)linear regression-M(N)LR-models. ...
