Question

1. Выпишите из 3-его абзаца предложение, содержащее инфинитив в функции определения, и письменно переведите его. Landsat data are less appropriate for quantification of cloud properties and amount compared to near daily global coverage and certain active cloud remote sensing systems although Landsat data have been valuable for cloud morphology analyses. However, quantification of the incidence of cloudiness for Landsat terrestrial monitoring applications, especially in persistently cloudy regions, is important because optically thick clouds preclude optical and thermal wavelength remote sensing of the surface. 2. Прочтите 5-й абзац текста и письменно ответьте на следующий вопрос: In what way do cirrus clouds influence the normalized difference vegetation index? The magnitude of cirrus cloud impacts on reflective wavelength data depends primarily on the cirrus cloud optical depth and studies have shown the relative impact of cirrus clouds on normalized difference vegetation index values of about 15%. Globally, cirrus clouds are thought to cover on average about 17% of the Earth’s surface.

The normalized difference vegetation index  depends on reflective wavelength which is attected by the magnitude of cirrus clouds.

Answer 2

1. "However, quantification of the incidence of cloudiness for Landsat terrestrial monitoring applications, especially in persistently cloudy regions, is important because optically thick clouds preclude optical and thermal wavelength remote sensing of the surface."

Перевод: Однако, количественная оценка встречаемости облачности для приложений мониторинга земной поверхности с использованием данных Landsat, особенно в регионах с постоянными облачными покровами, важна, поскольку оптически плотные облака препятствуют оптическому и тепловому дистанционному зондированию поверхности.

2. Cirrus clouds influence the normalized difference vegetation index (NDVI) through their impacts on reflective wavelength data. The magnitude of these impacts primarily depends on the optical depth of cirrus clouds. Studies have shown that cirrus clouds can cause a relative reduction in NDVI values of about 15%.
