Studying Long-Term Variations in Black-Sea Ecosystem Based on the Assimilation of Remote Sensing Data in a Numerical Model

Аннотация

The results of simulation of Black Sea ecosystem dynamics with the use of a three-dimensional interdisciplinary model are given. An important feature of the simulation is the assimilation of measurement data of satellite color scanners. The calculations were made for fifteen years starting from 1998. The result was a set of three-dimensional biogeochemical fields of the Black Sea on a regular grid with a time step of 1 day. The major biogeochemical parameters of the marine ecosystem were analyzed. The quality of the obtained fields was evaluated by comparison with the available data of in-situ measurements.
