Synthetic aperture radar data for measuring and monitoring forest carbon

About the training

In collaboration with the Bangladesh Forest Department (BFD), we are organizing this five-day training as part of our institutional capacity building approach.

The training will cover topics on microwave remote sensing, theory and concepts of synthetic aperture radar (SAR) imaging systems, SAR polarimetry, data types, scope and applications of SAR in Bangladesh, searching and accessing SAR data, processing techniques, visualization, information extraction, interpretation and analysis, and carbon estimation.

Objectives

The training aims to provide participants with theoretical and practical knowledge in using SAR data and applications to estimate above-ground forest biomass and forest carbon.

Expected outcomes

Upon completion of the training, the participants will have a better understanding of the concepts and general applications of SAR remote-sensing data and their potential and limitations. The training will enable participants to extract information from SAR observations and develop an above-ground forest carbon estimation model.

Expected participants

The course will bring together participants having basic knowledge and experience of remote sensing from BFD and ICIMOD.

Background

Forest biomass is an essential variable for assessing carbon sequestration and carbon balance in forest ecosystems. Therefore, accurate estimation of forest biomass is crucial for studying the carbon cycle of terrestrial ecosystems over large areas. Usually, forest biomass is estimated and monitored by conventional field measurements or remote sensing methods, and biomass calculations based on actual field measurements for a small forest stand are considered accurate. However, field-based measurements for computing forest biomass at the national scale are not feasible, as they are costly, labour intensive, and time consuming. Remote sensing-based methods, particularly the SAR microwave imaging system with cloud-penetrating and all-day data acquisition capabilities, provide viable alternatives to effectively measure and monitor forest biomass and forest carbon at national scales.
