"The SAR Handbook: Comprehensive Methodologies for Forest Monitoring and Biomass Estimation" is the culmination of a two-year collaboration between NASA SERVIR and SilvaCarbon. Five trainings, led by six SAR subject matter experts, were held at hubs throughout the SERVIR network. The topics of these trainings included SAR basics, SAR for forest change detection, forest height estimation, biomass estimation, mangrove monitoring, and sampling design. Each of these training topics are covered in a SAR Handbook chapter, which includes the theoretical basics and applied exercises. You can download the entire SAR Handbook (PDF) below, or explore individual chapters, trainings and one-pagers. Each chapter of the SAR Handbook is divided into a theory section, which discusses the scientific background of the chapter topic; a tutorial section, which provides step-by-step instructions on how to put the theory into practice; and additional tutorial materials, which include data, scripts and slideshows necessary to complete the tutorial.

NASA and global humanitarian organization Mercy Corps are partnering to help vulnerable communities in some of the most fragile places on Earth better withstand challenges such as population growth, resource scarcity and climate change. Eighty percent of Nigeriens are subsistence farmers. NASA and Mercy Corps are exploring how NASA’s satellite measurements can help the drought-prone, farming-intensive country create sustainable livelihoods for people like this Nigerien woman watering her garden. Credits: Mercy Corps/Sean Sheridan Under a three-year Space Act Agreement signed on March 29, the partnership will combine NASA’s Earth observation capabilities, including satellite data, imagery, and modeling and analysis, with Mercy Corps’ local insights and development expertise in more than 40 countries. Projects will assist communities in building resilience to complex stresses and making decisions that have long-term benefits for people and the environment. “This partnership enables NASA and Mercy Corps to amplify our collective capacities to reach communities in the most risk-prone regions of the world with the information they need the most,” said David Green, disasters program director in NASA’s Earth Science Division, Washington. “As NASA seeks to expand our understanding of the integrated Earth system from global to local scales, Mercy Corps’ extensive and practical knowledge of the human element – social, environmental, economic and political – is critical.”

Click here to view the full tweet and video. Dr. Amber Soja's work using remote sensing to study links between wildland fire and climate change was highlighted by NASA Earth on Twitter this week. The tweet came as a salute to women in science on International Women's Day. An interview with Dr. Soja posted on Twitter describes how she and her Applied Science teams use NASA data to reduce the cost of fire suppression through operational awareness, fire mitigation and prescribed landscape fires. Dr. Soja further describes how NASA data are used to identify deviations in Northern hemisphere, upper latitude landscape fires that are largely driven by changing climate. The interview has captured the attention of more than 16,000 followers, spreading valuable knowledge of Earth science.

On February 21st, Jeremy Kirkendall gave an overview of the NASA Disasters Mapping Portal during a panel session at the United States Department of Agriculture's (USDA) Agricultural Outlook Forum. There were approximately 75 people in attendance for the talk, which was very well received. Several new contacts were established with the USDA disasters staff and other researcheres who wanted to colloborate and share data with the Disasters Program. A number of people, including foreign users, expressed interest in ingesting near real-time services from the Mapping Portal to help with agricultural outlook forecasts and disaster recovery. The industry was very receptive of new data as they are always tyring to forecast the cost and yield of product.

ISS Georeferenced Digital Camera Images of Brumandinho Dam Area, Brazil This collection of visible-wavelength (red, green, blue or RGB) digital camera images were taken by astronauts onboard the International Space Station on February 2, 2019, then manually georeferenced by members of the Earth Science and Remote Sensing Unit at NASA Johnson Space Center. The images provide regional context, and may be useful for visualization of the event. Higher spatial resolution images may be suitable for spatial analysis to support decision making or subsequent research applications.
