Extensive forest changes have occurred in monsoon Asia, substantially affecting climate, carbon cycle and biodiversity. Accurate forest cover maps at fine spatial resolutions are required to qualify and quantify these effects. In this study, an algorithm was developed to map forests in 2010, with the use of structure and biomass information from the Advanced Land Observation System (ALOS) Phase...
Adverse impacts of climate change on the ecosystem have been a significant concern in last decades. However, studies related to water resources, especially northern Pakistan are great importance as this region is main supplier freshwater downstream areas. So, present study was carried out Chitral River Basin (CRB) investigate long term climatic and topographic changes. Spatiotemporal datasets f...
A new algorithm of retrieving atmospheric water vapor from MODIS near-infrared (IR) (NIR) data by using a regression fitting method based on Global Positioning System (GPS)-derived is developed in this work. The has been used to retrieve total column Moderate Resolution Imaging Spectroradiometer (MODIS) satellites both Terra and Aqua under cloud-free conditions solar radiation the NIR channels....
Land cover and land change information are essential data in terrestrial surface research. However, the products highly inconsistent, especially mountainous area. Most assessment studies focused on consistency of spatial patterns, while ignoring elevation heterogeneity. In this study, four were assessed for spatiotemporal Tibetan Plateau (TP), including Moderate resolution Imaging Spectroradiom...
Abstract Land cover in tropical marine climate zones is important for global change. The existing analysis of land product consistency mainly focuses on a continental or national scale and rarely takes different geographical (such as zones) examples to carry out micro-interpretation from the perspective ecology grid scale. In fact, some types under have poor accuracy due standard cognition comp...
The main challenge for land use efficiency is population growth. Using a coupling coordination model and the Sustainable Development Goal 11.3.1 (Land Consumption Rate to Population Growth Rate, LCRPGR), present study unravels evolution of types in Economic Community West African States (ECOWAS) from 2003 2019. We interpreted temporal based on long-time series Moderate Resolution Imaging Spectr...
The Leaf Area Index (LAI) is one of the most frequently applied measures to characterize vegetation and its dynamics and functions with remote sensing. Satellite missions, such as NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) operationally produce global datasets of LAI. Due to their role as an input to large-scale modeling activities, evaluation and verification of such datasets...
In this study, we integrated a remote-sensing fire product (MOD14A1) and land-use (MCD12Q1) to extract the number of crop-residue burning (CRB) spots radiative power (FRP) in China from 2001 2018. Moreover, conducted three trend analyses two geographic distribution quantify interannual variations summarize spatial characteristics CRB on grid (0.25° × 0.25°) regional scales. The results indicate...
Land degradation (LD) processes are widespread in drylands worldwide and accelerated by climate change. As a result, food security livelihoods at risk. Thus, there is need to monitor LD trends, especially agricultural areas. Mediterranean countries, including Tunisia Greece, concerned due the presence of drivers pressures causing land degradation. Through Trends.Earth plugin, SDG 15.3.1 indicat...
