This introductory webinar will cover the fundamentals of Solar Induced Fluorescence (SIF) and LIDAR, their applications, and an overview of different satellite data sources that are openly available. In addition, it will also include a step-by-step guide on how to access, open, and interpret SIF and LIDAR data.
SIF is a relatively new satellite retrieval, providing a direct measurement related to plant photosynthetic activity. It serves as a strong proxy to gross primary production (GPP), capturing dynamic responses of vegetation to stressors such as drought and temperature.
LIDAR is a system that illuminates a target and measures distance through the time taken for a pulse to reflect back to the sensor. LIDAR can be used to generate topography and vegetation height maps and retrieve digital elevation data necessary for flood modeling and vulnerability, along with risk analysis. They are valuable datasets for post-disaster assessment of debris deposition,…

The village of Avispa was hit by a flood event in 2008. 8 people died and various houses were destroyed. The high disposition for flooding still exists today. The Red Cross supports the community of Avispa in planning of protective measures. This requires a reliable hazard and risk analysis that takes into account the individuality of future events. For this purpose, the Red Cross combines qualitative and technical methods of analysis. In the presentation, these methods will be presented with a special focus on EO methods. In particular, reference is made to the use of GEE, where historical precipitation data are retrieved retrospectively for the last 40 years and can be used to calculate flood peaks. The benefits and limitations in practical application are demonstrated using Avispa as an example.
In addition, a new method for testing the cost-effectiveness of protective measures will be presented.
Speaker at the event will be Georg Heim, technical expert in…

From 29 June to 1 July 2021, ECMWF will host a 3-day virtual workshop on Global hydrological modelling and forecasting.
Format
The format of the workshop will be interactive and participants will have the opportunity to connect with people and their work through different sessions. Depending on the number of abstracts and the countries of authors/participants, we are planning to schedule the presentations in two blocks per day to accommodate people working in different time zones as far as possible. We thus envisage a first block of presentations from 9:00 to 11:00 BST and a second block from 16:00 to 18:00 BST.
Daily Agenda
Day 1 aims at presenting and discussing recent advances in global and large-scale hydrological modelling used in water cycle predictions up to medium-range, and in monitoring applications such as regional and global reanalyses. It will discuss the challenges involved in attaining skilful…

To continue efforts to make use of the opportunities made available by the space community, UN-SPIDER, NASRDA, NEMA and the Centre for Remote Sensing of Land Surfaces of the University of Bonn (ZFL) joined forces to carry out the UN-SPIDER/NASRDA/NEMA/ZFL National Virtual Expert Meeting on the use of Space-based Solutions for Disaster Risk Management and Emergency Response in Nigeria. The virtual expert meeting focused on the use of space technologies to improve disaster risk reduction in Nigeria. Specifically, the goal of the meeting was to contribute to the efforts conducted by NEMA in the area of disaster risk reduction, preparedness, early warning systems, disaster response and recovery efforts. Outcomesof this Expert Meeting included, but were not limited to:
- Enhancing space-based disaster management efforts in Nigeria
- Improving capacity to use earth observation data to manage disasters in Nigeria
- Raising…
Facebook Connectivity Lab in collaboration with the Center for International Earth Science Information Network (CIESIN) at Colombia University combines machine vision AI with satellite imagery and census information to create population density maps. With the integration of demographic information, specifically related to age and gender, these maps collectively provide information on both the location and the demographic of a population in a certain country. The population density maps cover the majority of countries around the world.Publishing institution:-

Natural lakes and man-made reservoirs are a part of Earth’s surface water. Freshwater lakes and reservoirs are used for drinking water, fishing, and recreational activities. Aside from the aesthetic and scenic value added by their presence, lakes support surrounding plant and aquatic ecosystems and wildlife. A variety of factors affect lakes and reservoirs, including climate variability and change, land use, and other watershed activities influencing surface runoff and groundwater. Therefore, monitoring the water quantity and quality of lakes and reservoirs is crucial for their sustainable management. This training focuses on introducing remote sensing observations for monitoring the water level of lakes; a critical surface water component affecting the residential, economical, and recreational sectors in the area. Recent observations of lake bathymetry based on remote sensing observations will also be presented.

Having reliable and timely population distribution data can make a life or death difference for individuals facing crises or living in conflict-ridden regions. These data are also essential for development decision-making and planning and for monitoring progress towards the UN Sustainable Development Goals (SDGs) established by the international community. We need to know where people are located, what conditions they are facing, what infrastructure is available, and what basic services they can access. We also need to ensure that no one is left off the map in pursuit of meeting the SDGs.
Gridded population data, which often use remote sensing inputs to improve the spatial allocation of population within a country, are vital for all these purposes. Together with the growing variety of applications that require spatial population data, there is now a bewildering array of population grids, and users need to know which ones are most suitable for their applications…

The European Space Agency, in the context of the "Earth Observations Science for Society" Programme, and CNES are organising a sequel event to Hydrospace2015, called 4th Space for Hydrology Workshop - "Inland Water Storage and Runoff: Modeling, In Situ Data and Remote Sensing", Monday 7 - Friday 11 June 2021, hosted at ESA-ESRIN, Frascati, Italy. This time around the Hydrospace Workshop is organised in collaboration with the GEO Global Water Sustainability Initiative (GEOGloWS) - see the Objectives page - looking for opportunities to explore joint solutions with a broader view on key science questions for Research and Development, up to Operational use of remote sensing information. The aim of getting together during 4~4.5 days is to strengthen the collaboration between the four critical water communities: in situ, modelling and space observation scientists as well as “non-scientific” users such as water managers to address the needs of the application community.
The European Space Agency is organising the 11th International Workshop on “Advances in the Science and Applications of SAR Interferometry and Sentinel-1 InSAR”, Fringe 2021.
Format
Fringe 2021 is organised around:
- Papers and e-posters selected by the Scientific Committee;
- Invited papers on ESA-funded studies and Sentinel-1 and future ESA SAR mission status reports;
- Round-table discussions with seed questions prepared by the session chairpersons and ESA.
The event will take place from 31 May - June 4 2021. No participation fees will be charged.
Objectives
- To bring together the global InSAR research and development communities and facilitate international exchange between researchers and research groups;
- To present the Sentinel-1 mission status, algorithms and products;
- To review and assess the progress according to the…
