On December 11, 2013 the Moderate Resolution Imaging Spectroradiometer aboard NASA’s Terra satellite flew over Argentina and captured this true-color image of a sunny spring day across the region.
Light lines of popcorn clouds float over the greening land near the Río de La Plata and its tributary rivers, while a wispy cloud bank hovers over the pampas. Tan sediment fills the Río de La Plata, and an electric blue arc in the Argentine Sea marks the proliferation of phytoplankton – tiny plant-like organisms that grow in large blooms in this region each spring.
Most of the land in the image belongs to the Province of Buenos Aires, the largest and the most heavily populated province in Argentina. The province contains about 11% of the country’s total area, and about 39% of the population. Most of the people live in the city of Buenos Aires, which appears in this image as a large gray area on the southern bank of the Río de La Plata.
