Abstract
Данные дистанционного зондирования Земли за последние два десятилетия обрели широкое распространение в практике решения гидрологических задач. На их основе формируются комбинированные наборы метеорологической информации, позволяющие качественно новым образом оценить основные элементы водного баланса крупных речных бассейнов. Особенно это актуально в условиях нерегулярных станционных наблюдений. Данная работа посвящена оценке применимости глобальных сеточных массивов гидрометеорологической информации в расчетах элементов водного баланса крупных речных бассейнов. В качестве оцениваемых массивов были выбраны комбинированный архив MSWEP v.2 об осадках, а также GLEAM v.3.1 об испарении. Кроме этого, отдельным аспектом данной работы является оценка применимости сеточных гравиметрических данных GRACE в расчетах аккумуляционной составляющей уравнения водного баланса.
Over the past two decades, Earth remote sensing data have become widespread in the practice of solving hydrological problems. On their basis, combined sets of meteorological information are formed, allowing qualitatively new way to assess the main elements of the water balance of large river basins. This is especially true in conditions of irregular station observations. This work is devoted to the assessment of the applicability of global grid arrays of hydrometeorological information in the calculation of the water balance elements of large river basins. As a graded arrays was chosen as a combined archive MSWEP v.2 rainfall and GLEAM v.3.1 about the evaporation. In addition, a separate aspect of this work is the assessment of the applicability of grid gravimetric data GRACE in the calculation of the accumulative component of the water balance equation.
