Abstract
Cilj rada je odrediti najbolju metodu procjene prosječnog vertikalnog koeficijenta atenuacije dolje usmjerene iradijance vodenog medija iz mjerenja podvodne i površinske dolje usmjerene iradijance. Analizirani podatci su prikupljeni u sklopu projekta Hawaii Ocean Time-Series, te su javno dostupni. U procjeni su upotrijebljene i uspoređene četiri metode. Metode su bazirane na metodi najmanjih kvadrata, jednadžbi prodiranja svjetlosti, rješenju jednadžbe prodiranja svjetlosti i Lambertovoj W funkciji, koja nikada prije nije upotrijebljena za rješavanje fizikalnog problema ove vrste. Metode su uspoređene na temelju vrijednosti koeficijenta determinacije između izmjerenih i procijenjenih vrijednosti. Najbolji rezultati su postignuti upotrebom metode bazirane na metodi najmanjih kvadrata, koja je ujedno i najoptimalnija po pitanju računalnih zahtjeva.
Abstract (english)
The main goal of the thesis is to determine the best method for estimating average vertical attenuation coefficient of downward irradiance of water medium from the measurements of underwater and surface downward irradiance. Data used in the analysis were collected as a part of the Hawaii Ocean Time-Series project and are publicly available. Total of four different methods were implemented and compared. Methods are based on the least squares method, light penetration equation, the solution of the light penetration equation and the Lambert W function, which has never before been used for this kind of problem. Methods were compared on the basis of determination coefficient between measured and estimated values. The best result was achieved by the method based on the least squares method, which also had the least computational requirements.
