ABSTRACT Change detection information is of vital importance for environmental monitoring and planning. The North American Land Change Monitoring System (NALCMS) provides such a preliminary product for changes between 2005 and 2010 for the North American continent in a standardized and consistent manner. This paper presents the change detection method and results for the Mexican section of the study area. Based on 250m MODIS data changes were found for 0.39% of the national area. Some visually clear examples such as urban sprawl around growing cities like Cancun and lake level changes are described in more detail.

The total annual deposition ranged from 1.27 to 1.58 gm −2 for sulfur, 0.8 to 0.85 gm −2 for nitrogen, and 3.81 to 4.69 mgm −2 for phosphorus. More than 90% of the phosphorus and about two-thirds of the sulfur and nitrogen were deposited... more

The aerosol optical thickness (AOT) is known as blocking particles which avoid the transmission of solar radiation coming from the Sun, and is defined as the integral of the coefficient of extinction over a vertical column of the Atmosphere. This coefficient of extinction is also defined as the limited fraction of the irradiance over the trajectory at a specific wavelength. The MODIS (Moderate Resolution Imaging Spectroradiometer) sensor provides aerosol data products all over the planet. However this data requires constant evaluation and validation using in-situ data such as the provided by the network of photometers managed by AERONET (Aerosol Robotic Network). In this work, the procedure of validation of the MODIS AOT data using AERONET data in the wavelengths of 660 and 675 nm is presented. It is expected that using validate remote sensing data which provides spatial and temporal information about the AOT will help to a better understanding of the behavior of the complex atmosph...
