Greece images by NASA Earth Observatory

SANTORINI

The islands in this photograph (taken from the International Space Station) are arranged in an oval shape. They are all that remains of what was once a large, circular volcano.

ATHENS

The ISS-9 Space Station crew obtained this high-resolution image of the western Athens area in June of 2004, allowing for detailed observations of land cover and land use changes in the urban area.

CRETE

The western and central parts of Crete appear surrounded by quicksilver in this astronaut photograph taken from the International Space Station. This phenomenon is known as sunglint, caused by light reflecting off of the sea surface directly toward the observer. The point of maximum reflectance is visible as a bright white region to the northwest of the island. Surface currents causing variations in the degree of reflectance are visible near the southwestern shoreline of Crete and the smaller island of Gavdos (image lower left).

CORINTH CANAL

On May 9, 2005, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terrasatellite took this picture of the Corinth Canal and the surrounding area. The canal itself appears as a razor-thin blue strip running diagonally through the isthmus. On either side of the canal, straight lines and sharp lines indicate an urbanised environment, dissected by the occasional meandering highway.

PELOPONESSE

This photo from an astronaut on the International Space Station shows much of the nation of Greece. The urban region of Athens is recognisable due to its size and light tone compared to the surrounding landscape; the smaller cities of Megara and Lamia also stand out. Dark-toned mountains with snow-covered peaks contrast with warmer, greener valleys where agriculture takes place. The intense blue of the Mediterranean Sea fades near the Sun’s reflection point along the right side of the image, and numerous wind streaks in the lee of the islands become visible.

MOUNT OLYMPUS 

Mount Olympus is the highest peak in Greece. The 2,917-meter (9,570-foot) summit is the tallest in a mountain chain that runs north into Bulgaria and south into Turkey, via the Cyclades Islands. In this winter view, Olympus is the only peak with a dusting of snow—perhaps the reason its name in classical Greek means “the luminous one.” In Greek mythology, the peak was inhabited by the Twelve Olympians, the most famous gods of the ancient Greeks. North of Mount Olympus lies Macedonia, the homeland of Alexander the Great. Climbing the famous mountain is a favourite tourist activity today.

FIRES IN GREECE

Flames raced through the forests northeast of Athens, Greece, on August 22, 2009, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image. Areas where the sensor detected fire on the ground are outlined in red.

This image of Greece was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite on August 26, and places where MODIS detected actively burning fires are outlined in red. A line of fires stretches along the western coast of Greece’s Peloponnesus Peninsula. To the northeast, a large fire is casting a plume of smoke over Athens. With its brownish tinge, the smoke pooled over the Gulf of Sirte could easily be mistaken for dust from the deserts of Libya. Dust storms often travel the other direction across the Mediterranean: from Africa to Greece.

SNOW IN GREECE

An unusual storm dumped snow on Athens, Greece, on January 29, 2008, reported Reuters. Snow still covered the mountains north of the city when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terrasatellite captured this image the following morning. The city of Athens, cement grEy against the pale olive green of the surrounding landscape, appeared to be snow-free except for the northern fringes. Athens was not the only Greek city to experience a wintry blast of snow and wind on January 29, said Reuters, and this, too, is reflected in the image. Mountains throughout Greece are coated with snow in the large image. According to the Greek National Tourism Organisation, snow is not unusual in the mountains of Greece during the winter.

3D VIEW OF ATHENS

This perspective view was made from an image acquired April 29, 2004, draped over a digital elevation model (DEM) created from the same Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) scene.

DUST OVER GREECE

Powerful winds pulled a thick band of desert dust from Egypt and Libya over the Mediterranean Sea on April 17, 2005. The dust is so thick that Crete is completely obscured from view, and the ground of Greece is barely visible. African dust frequently blows over the Mediterranean in the spring, carrying tons of dust into Greece. This particular storm shrouded the country in a yellow haze that cancelled or delayed flights and halted sea transport, according to local news reports. The winds that produced this dust storm blew at an average of 75-89 kilometers per hour (47-55 mph) near the sea’s surface, and stronger winds prevailed higher in the atmosphere. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this photo-like image of the storm.
