Photosynthetic Activity of Italy and Coastal Tunisia and Algeria

Italy - November 17th, 2009

This FAPAR image shows the vegetation index of Italy, including the islands of Sardinia and Sicily, as well as Corsica and parts of coastal Tunisia and Algeria. The vegetation index corresponds to the Fraction of Absorbed Photosynthetically Active Radiation, which provides data on the planet’s climate system.

In FAPAR images, the color spectrum over land runs from red (1.0), to green, to yellow and white (0.0), while bodies of water appear blue. Dark red regions correspond to agricultural zones for which there is high photosynthetic activity and therefore vegetation productivity, while yellow to white areas, with the exception of white patches of clouds,  indicate a low degree of photosynthetic activity.

Here, some red areas can be seen on the islands of Sardinia and Sicily, while most of Italy and Corsica appears green with some yellow zones. Algeria and Tunisia show photosynthetic activity near the coast, while the area further south is yellow and white, reflecting the low photosynthetic activity of more arid regions.

Sicily in Early Autumn – November 20th, 2009

Sicily, Italy - October 7th, 2009

The Italian island of Sicily shows more green vegetation in this image, taken in early autumn, than it does in the hotter and drier summer months (click here for an image of the area in summer). The skies are virtually cloud free, and the summit and flanks of Mount Etna are clearly visible as a dark brown area near the eastern shores.

In the upper right corner, the Strait of Messina separates Sicily from the Italian mainland region of Calabria. Also visible near the top of the image are the Aeolian Islands, also known as the Lipari Islands, arranged in an arched shape in the Tyrrhenian Sea.

Southern Italy, Between the Tyrrhenian and Adriatic Seas and the Gulf of Taranto

Italy - October 7th, 2009

The terrain of southern Italy appears divided in two, between the flatter lands near the Adriatic Coast (above) and the more mountainous terrain towards Tyrrhenian Sea (below).

Upon opening the full image, many cities and towns in the Apulia region appear as tan circular areas on the flatter Adriatic side. The main exception to this generally plain-like topography is the Gargano Peninsula (top left corner), home to Monte Gargano.

Also of note on the peninsula are Lake Lesina  (left) and Lake Varano (right), both dark green, separated from the Adriatic by a thin strip of land and dunes. Sediments line the coast of the peninsula, particularly to the right. Other swirls of sediments are also visible in the full image along the shores of the Gulf of Taranto (right).

Continuing to the right along the shoreline, towns cities such as Bari appear as tan patches amidst the green terrain. On the bottom right, by Apulia’s border with the Basilicata Region, the Basento River spills tan sediments into the Gulf of Taranto.

The Cities of Venice and Mestre, South of the Piave River in Northern Italy

45.4N 12.3E

Italy - October 7th, 2009

The city of Venice, capital of the Veneto Region is northern Italy, appears as a fish-shaped white island in the Venetian Lagoon along the Adriatic Sea. The city actually stretches across 118 small islands in the marshy lagoon.Visible on the Italian mainland across from the island is the city of Mestre.

The saltwater lagoon itself stretches along the shoreline between the mouths of the Po and the Piave Rivers. Here, the Piave can be seen flowing towards the Adriatic north of the lagoon. It begins in the Alps and flows southeast for 220 km (135 miles) into the sea.

The Active Delta of the River Po in Italy, South of Chioggia

The River Po flows eastward across northern Italy to the Adriatic Sea. Here, its delta can be seen along the shores of the sea. Along the coast, northwest of the delta, is the coastal town of Chioggia in the Veneto Region, situated on a small island at the southern entrance to the Lagoon of Venice. It appears here as a white area at the top center.

The most recent part of the Po Delta projects into the Adriatic between Chioggia and Comacchio. It contains channels that actually connect to the Adriatic and on that account is called the active delta by the park authorities, as opposed to the fossil delta, which contains channels that used to but no longer connect the Po to the Adriatic.

The active delta was created in 1604 when the city of Venice diverted the main stream, the Po grande or Po di Venezia, from its channel north of Porto Viro to the south of Porto Viro in a channel then called the Taglio di Porto Viro, or “Porto Viro cut-off.”
