Brazilia and Paranoá Lake, Brazil15.7S 47.9W
Brazil’s capital city, Brasília, in the country’s Federal District (occupying the central portion of the image), is located in a region called Planalto Central. This dry region has only two seasons: wet and dry.
During the dry season (winter), the humidity can reach critical levels, mainly in the peak hours of the hottest days. The artificial lake of Paranoá, with almost 40 km2 (15 sq mi) and 500 million cubic metres (410,000 acre·ft) of water, was built exactly to minimize the severe climatic conditions of the winter.
Brasília itself can be seen in the full image as a greyish area, left of center, between the Parque Nacional do Brasilia, a brownish patch of land with the Santa Maria Reservoir in the center, and the irregularly shaped Paranoá Lake just to the east of the national park. The other brownish patch below the lake is Brasília’s Botanical Garden.
