Содержание влаги в почве (объёмный %) для всасывания 33 кПа и 1500 кПа, прогнозируемое на 6 стандартных глубинах (0, 10, 30, 60, 100 и 200 см) с разрешением 250 м
Точки обучения основаны на глобальной компиляции почвенных профилей:
Инструкции по импорту данных доступны здесь . Инструкции по пространственному прогнозированию подробно описаны здесь . Примечание: это фактически измеренные и нанесенные на карту значения почвенного состава; педо-передаточные функции не использовались (за исключением заполнения отсутствующих значений плотности насыпного веса NCSS). Доступная влагоемкость в мм (полученная как разность между полевой влагоемкостью и температурой завядания, умноженной на толщину слоя) для каждого слоя доступна здесь . Антарктида не включена.
