Investigation of the Dependence of Satellite-Based Precipitation Estimate Errors to Distance from the Coastline In this study, Tropical Rainfall Measuring Mission (TRMM) 3B42 v7 satellite based rainfall data are verified by using cumulative monthly rainfall data measured at 257 stations operated by the General Directorate of Meteorology between 1998 and 2014. Long-term mean values of station-based and satellite-based rainfall data, correlation between them, Standard deviation of monthly average and anomaly components, and standard deviation of satellite based data error are analyzed. Variation of satellite-based data error with elevation and distance from coasts is the major focus of this study. The results show that, especially the anomaly component of satellite-based rainfall data error is much higher at low-elevation regions and coastal regions compared with high-elevation regions and interior regions.

Investigation of the dependence of satellite-based precipitation estimate errors to distance from the coastline Uydu Kaynakli Yaǧmur Verilerinin Hata Oranlarinin Deniz Kiyilarina Olan Uzakliǧa Baǧli Analizi YILMAZ, MERİÇ; Amjad, Muhammad; Bulut, Burak; Yılmaz, Mustafa Tuğrul (2017-01-01) In this study, Tropical Rainfall Measuring Mission (TRMM) 3B42 v7 satellite based rainfall data are verified by using cumulative monthly rainfall data measured at 257 stations operated by the General Directorate of Meteorology between 1998 and 2014. Long-term mean values of station-based and satellite-based rainfall data, correlation between them, Standard deviation of monthly average and anomaly components, and standard deviation of satellite based data error are analyzed.

Evaluating and merging model- and satellite-based precipitation products over varying climate and topography Amjad, Muhamma; Yılmaz, Mustafa Tuğrul; Department of Civil Engineering (2020) Before using the satellite- and model-based precipitation retrievals in hydrological studies, their uncertainty assessment is crucial. Improving their performance accuracy is another important issue worth consideration. This study first evaluates and intercompares a set of nine precipitation products (2 satellite estimation-based, 2 model reanalysis-based, and 5 model forecast-based products) over varying climate and topography by using the in-situ observed precipitation data as truth. The products were the...
Numerical solution to kinematic wave equation for surface runoff analysis using satellite based DEM data Yıldırım, Hasan Hüseyin; Aydın, İsmail; Department of Civil Engineering (2020-9) Modeling of rainfall runoff over large catchment areas is a critical step in flood analysis to estimate the time-wise variation of discharge at the outlet of hydrological basin. Outlet hydrograph of a basin is generally estimated using empirical formulations based on measurements from previous rainfall events. However, these empirical methods may not correctly model the surface flow dynamics over large and complex geometries. In this study, a fully distributed numerical model is developed that can deal with...
Analyses of atmospheric and marine observations along the Turkish coast Tutsak, Ersin; Özsoy, Emin; Department of Physical Oceanography (2012) Time series and spectral analyses are applied to meteorological data (wind velocity, air temperature, barometric pressure) and sea level measurements from a total of 13 monitoring stations along the Turkish Coast. Analyses of four-year time series identify main time scales of transport and motion while establishing seasonal characteristics, i.e. distinguishing, for instance, between winter storms and summer sea-breeze system. Marine flow data acquired by acoustic doppler current pro filers (ADCP) is also a...
Chemical composition of precipitation at different parts of Turkey Ayaklı, Gül; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2014) In this study major ion composition of rain water samples collected at General Directorate of Meteorology Antalya, Balıkesir and Trabzon rain sampling stations were analyzed. The major ions SO42-, NO3-, NH4+, Cl-, Ca2+, K+ and Na+ were analyzed by ion chromatography. Data generated in these stations are compared to evaluate how chemical composition of rainwater changes as air masses travel on the Anatolian plateau. Data also demonstrate how rainwater composition varies seasonally at different parts of Turke...
