The solar energy potential of Ankara, Turkey, (39.89 degrees N, 32.78 degrees E) has been investigated using the measurements of global and beam radiation over the period May 2008 to May 2009. Surface air temperature was also measured and variation in clearness index evaluated over this period. Global and beam radiations have been analyzed using hourly, daily and monthly averages obtained from 1-minute averages of recorded data. Results show that annual average daily global and beam radiations were 17.04 and 15.72 MJ/m(2)/day, respectively, for this period. The results are compared with the data available for several other cities in Turkey. The study shows that Ankara has a large solar potential. The consistency of these data with that from the State Meteorological Service (SMS) weather station in Ankara was analyzed. Significant differences between these 2 stations were found and are attributed to measurement error at the SMS station. New radiation-measurement stations should be established to create a better national radiation database for Turkey.

Estimation of total solar radiation from bright sunshine hours in Turkey Taşdemiroğlu, Erol; Sever, Rita (Elsevier BV, 1989-12) Measurements of total solar radiation and bright sunshine hours in six different climatological locations in Turkey are used to develop an Angstrom type equation. The coefficients are found for a linear equation from regression analysis for these locations. A simple overall equation, which yields the solar radiation in any location in Turkey for bright sunshine hours, is developed. The results of this equation, together with the results obtained from five similar, internationally accepted correlations, are ...
Sensitivity and sea surface temperature analyses of WRF model for predicting heavy rainfall events observed in Eastern Black Sea and Mediterranean regions of Turkey Pilatin, Heves; Yücel, İsmail; Kentel Erdoğan, Elçin; Department of Earth System Science (2020-8) With this thesis it is aimed to enhance the prediction accuracy of the Weather Research and Forecasting (WRF) model on the extreme precipitation events of Mediterranean and Eastern Black Sea regions of Turkey. While the first part of sensitivity analysis was conducted for the physical parameters (microphysics, cumulus and PBL) and the initial boundary conditions, the second part has only focused on the impact of sea surface temperature (SST). After choosing 4 microphysics, 3 cumulus, 2 PBL and 2 input meteo...
Analysis of sunshine duration between 1970 and 2010 for Turkey Yıldırım, Uğur; Akınoğlu, Bülent Gültekin; Yılmaz, İsmail Ömer; Department of Earth System Science (2013) In this thesis, 41 years of bright sunshine duration (SD) data of 192 meteorological stations in Turkey were analyzed. The main objective is to determine the trends of SD data and the importance of such analyses is the high correlation between SD data and solar irradiation reaching the surface of the earth. Because of the missing value problems, only the data set for 72 stations were examined. After imputing missing values of these stations by expectation maximization algorithm, to test the homogeneity Krus...
Estimation of diffuse component for two locations in Turkey Karaveli, Abdullah Bugrahan; Akınoğlu, Bülent Gültekin (2016-10-14) In analyzing the solar energy systems, the first step is the accurate measurements/estimations of the input in the long term: solar irradiation incident on the panels. The measurements are lacking in many places so the estimation procedures should be developed using the measured data of the locations having similar climates and close in latitudes. In most life cycle assessments, monthly averages of daily values are utilized in the form of typical meteorological year or simply with the averages of a year or ...
Microwave metamaterial absorber for sensing applications BAKIR, MEHMET; KARAASLAN, MUHARREM; ÜNAL, EMİN; AKGÖL, OĞUZHAN; Sabah, C. (Elsevier BV, 2017-12-01) A metamaterial absorber (MA) based sensor is designed and analysed for various important applications including pressure, temperature, density, and humidity sensing. Material parameters, as well as equivalent circuit model have been extracted and explained. After obtaining a perfect absorption (PA) at around 6.46 GHz and 7.68 GHz, surface current distributions at resonance points have been explained. Since bandwidth and applicability to different sensor applications are important for metamaterial sensor app...
