In this paper, the changes in the ionosphere over Turkey due to two solar eclipses are reported. TEC on the eclipse day (26 April 1976) and the intensity of an HF radio wave during its propagation over 567 km between Ankara and Elazig on the eclipse day (11 August 1999) exhibited a very marked decrease.

Accuracy assessment of MODIS daily snow albedo retrievals with in situ measurements in Karasu basin, Turkey Tekeli, AE; Sensoy, A; Sorman, A; Akyürek, Sevda Zuhal; Sorman, U (Wiley, 2006-03-15) Over the ablation period of 2004, daily snow albedo values retrieved from the moderate-resolution imaging spectroradiometer (MODIS) Terra were compared with ground-based albedo measurements. Two data sets are used for this study. The first data set is from two automatic weather stations (AWS) located at fixed points in Karasu basin in eastern Turkey. This provided the temporal assessment of MODIS daily snow albedo values. The second data set, consisting of 19 observation points randomly distributed around o...
MEASUREMENT OF SOLAR RADIATION IN ANKARA, TURKEY Caglar, Ahmet; Yamali, Cemil; Baker, Derek Keıth; KAFTANOĞLU, BİLGİN (2013-01-01) 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 an...
Uncertainty assessment in projection of the extreme river flows, the case of Ömerli catchment, İstanbul Engin, Batuhan Eren; Yücel, İsmail; Yılmaz, Ayşen; Department of Earth System Science (2015) The average temperature at the surface of the Earth has been increasing over the past century due to the increased greenhouse gases concentrations in atmosphere through anthropogenic activities. Rising temperature leads to an increase in evaporation and thus intensifies the components of water cycle which results in extreme flows in different parts of the world through changes in globally averaged precipitation. Projection of extreme flows is very important in this aspect, yet obscurity about many factors t...
Solar energy R&D, technology and economics in Turkey Taşdemiroğlu, E (Elsevier BV, 1990-1) The solar energy potential of Turkey is assessed. Solar energy R&D programs and technology and the present market for flat-plate solar collectors are briefly reviewed. The potential share of solar energy in the total energy budget is estimated.
Assessment of changes in climate indices of the mediterranean climate region of Turkey Çetinkaya , İzem; Yücel, İsmail; Department of Civil Engineering (2020-10-28) As a consequence of climate change, frequency and intensity changes in extreme weather events have occurred. One of the most vulnerable regions of the world that is affected by the climate change is the Mediterranean region. Turkey as a Mediterranean country has a great importance to investigate the changes in climate behavior. 57 stations from Mediterranean climate region of Turkey have been selected as the study area for this thesis. This study aims to assess the climate indices that carry the valua...
