A grey veil of Haze in northern Italy covers the Po River Valley of northern Italy and stretches out over the Adriatic Sea in this true-color Terra MODIS image from March 17, 2005.
The snow-capped Alps to the north help to restrict air flow between northern Italy and the rest of continental Europe.
Many of Italy’s major cities and industrial centers are located in this valley, further adding to the problem.
A lone red dot near Milan marks a spot where the MODIS instrument detected a heat anomaly (likely a small fire).
As the sediment disperses, the color of the water blends with the brown of the sediment to create varying shades of blue, green, and turquoise.
Also in the case of microscopic marine organisms, light reflects off of the chlorophyll that they use to turn sunlight into energy.
