Mexico - May 11th, 2012

Plumes of smoke from multiple fires by the Sierra Madre Occidental, parallel to the west coast of Mexico, can be observed in this image. Also parallel to the shoreline is a trail of bright green sediments in the Gulf of California (Sea of Cortez). Upon opening the full image, more smoke can be seen further east: smoke released from fires between the Isthmus of Tehuantepec and the Yucatán Peninsula creates a hazy cloud over the Gulf of Mexico.

Mexico - April 21st, 2012

Several fires can be seen in and near the state of Durango, Mexico. The largest is located on the right side of the image, near the middle, south of the Santiaguillo Lagoons. This fire releases a large plume of smoke towards the east. Other fires can be observed closer to the coast, southwest and northwest of the main blaze.

The state of Durango is located in Northwest Mexico. Most of the state is heavily mountainous and a good part forested; the Sierra Madre Occidental occupies the western and central part of the state. Vast desert basins in the Laguna District are irrigated by the Nazas River, which also supplies water to the aforementioned Santiaguillo Lagoons.

Mexico - April 14th, 2012

Mexico is crossed from north to south by two mountain ranges known as Sierra Madre Oriental and Sierra Madre Occidental, which are the extension of the Rocky Mountains from northern North America. Here, these two ranges can be seen parallel to the coastline. From east to west at the center, the country is crossed by the Trans-Mexican Volcanic Belt also known as the Sierra Nevada. A fourth mountain range, the Sierra Madre del Sur, runs from Michoacán to Oaxaca. As such, the majority of the Mexican central and northern territories are located at high altitudes.

Good Vegetation Index Along Mexico’s Pacific Coast

Mexico - January 2nd, 2012

This FAPAR image shows the vegetation index of the Pacific Coast of Mexico. The index is highest along the coastal plain, with good levels of photosynthetic activity indicated by green false-coloring, and a few patches of high activity indicated by rusty-red coloring.

As one moves further inland and up the slopes of the Sierra Madre Occidental mountain range, the index of photosynthetic activity becomes gradually lower, as is indicated by the light yellow color. The index is also low around Lake Chapala, an alpine lake located at an altitude of 1500 meters above sea level.

Mexico - October 17th, 2011

The Sierra Madre Occidental is a mountain range that lies approximately 300 kilometers inland from the west coast of Mexico at its northern end but approaches to within fifty kilometers of the coast near the Cordillera Neovolcánica.

The northwest coastal plain is the name given the lowland area between the Sierra Madre Occidental and the Gulf of California.Here this area of plains appears mostly dark green in color.

Visible beyond the Sierra Madre Occidental is the Mexican altiplano, stretching from the United States border to the Cordillera Neovolcánica, occupies the vast expanse of land between the eastern and western sierra madres. Various narrow, isolated ridges cross the plateaus of the northern altiplano. Numerous depressions dot the region, the largest of which is the Bolsón de Mapimí.
