MODIS Pic of the Day 24 April 2021
April 24, 2021 - Sunshine over Western Europe



Sunny skies accentuated the verdant spring beauty of Western Europe on
April 23, 2021. The Moderate Resolution Imaging Spectroradiometer
(MODIS) on board NASA’s Terra satellite acquired a stunning,
cloud-free, true-color image centered on France on that same day.

The darkest greens are created by coniferous forests, which retain
their needles year-round. Deciduous forests, which are greening as
leaves burst forth in the worming weather, are almost equally as dark
as conifers. Agricultural lands and grasslands are painted in lighter
greens. Large areas of human structures, such as cities and major
roadways, are marked by gray pixels.

The contrast in colors of the land cover can be illustrated by finding
the relatively small, nearly-round very dark green area just north of
center in this image. These greens are an area dominated by conifer
forest. Moving north, an arc of lighter green colors an agricultural
area that is often used for winter crops, but also supports spring
cropping and pasture. If viewed at high resolution (250 meters), its
easy to see a patchwork of tan (open land), light green (new crops) and
darker greens (older crops/trees) which is typical of farmland. A
smudge of gray sits north of the agricultural arc. This is the city of
Paris, home to more than 11 million people and the capital of France.
At higher resolutions you can see the Seine River flowing through the
city of Paris as well as the surrounding countryside.

Several European countries border France and can be seen in this image.
Starting in the north and moving clockwise France borders: Belgium,
Luxembourg, Germany, Switzerland, Italy, Monaco, the Mediterranean Sea,
Spain, Andorra, the Bay of Biscay, and—across the English Channel—the
United Kingdom.
