  • Aeolus is an ESA satellite that provides global observations of wind profiles. It is the first wind satellite that can measure winds globally, as it is able to calculate atmospheric winds also in cloud-free areas or winds throughout vertical wind columns. Aeolus can provide high-quality short and medium-range forecasts (between three to ten days ahead) both of the northern and the southern hemispheres. It can also produce useful information on ocean salinity and frozen expanses as well as insights into the wind’s influence on heat and soil moisture within the Earth's surface. The measurements from the satellite can contribute to long-term climate research and help scientists better understand global environmental challenges such as extreme natural disasters, global warming, and air pollution.
    Aeolus is equipped with an Atmospheric Laser Doppler Instrument, called Aladin. Aladin comprises powerful lasers, one of the largest telescopes ESA has put…

  • NOAA-20, designated JPSS-1 prior to launch, is the first of the United States National Oceanic and Atmospheric Administration's latest generation of U.S. polar-orbiting, non-geosynchronous, environmental satellites called the Joint Polar Satellite System. NOAA-20 was launched on 18 November 2017 and joined the Suomi National Polar-orbiting Partnership satellite in the same orbit. NOAA-20 operates about 50 minutes ahead of Suomi NPP, allowing important overlap in observational coverage. Circling the Earth from pole-to-pole, it crosses the equator about 14 times daily, providing full global coverage twice a day. This will give meteorologists information on "atmospheric temperature and moisture, clouds, sea-surface temperature, ocean color, sea ice cover, volcanic ash, and fire detection" so as to enhance weather forecasting including hurricane tracking, post-hurricane recovery by detailing storm damage and mapping of power outages.

    The project incorporates five instruments,…

  • Himawari 9 is a Japanese weather satellite, the 9th of the Himawari geostationary weather satellite operated by the Japan Meteorological Agency.

  • Himawari 8 is a Japanese weather satellite, the 8th of the Himawari geostationary weather satellites operated by the Japan Meteorological Agency. The spacecraft was constructed by Mitsubishi Electric with assistance from Boeing, and is the first of two similar satellites to be based on the DS-2000 satellite bus. Himawari 8 entered operational service on 7 July 2015 and is the successor to MTSAT-2 (Himawari 7) which was launched in 2006.

  • Serving as part of the Global Precipitation Measurement (GPM) mission, an international network of satellites that provide next-generation global observations of rain and snow, the GPM “Core Observatory” satellite carries an advanced radar / radiometer system to measure precipitation from space and serve as a reference standard to unify precipitation measurements from a constellation of research and operational satellites. The GPM mission builds upon the success of the Tropical Rainfall Measuring Mission (TRMM). Through improved measurements of precipitation globally, the GPM mission is helping to advance our understanding of Earth's water and energy cycles, improve forecasting of extreme events that cause natural hazards and disasters, and extend current capabilities in using accurate and timely information of precipitation to directly benefit society.

  • Natural disasters are becoming more frequent and intense across the globe. Enhancing resilience to increasing hazards, exposure, and vulnerability therefore requires leveraging of advanced geospatial technologies for better disaster mitigation and management. With continuous improvements in satellite data sensor acquisition parameters together with geo-computational approaches, geospatial technologies have emerged as the most powerful technology for all phases of disaster management. The course on advanced geospatial technologies for Disaster Risk Reduction (DRR) is scheduled from April 18 - 29, 2022 .

  • On 31 August 2021, the World Meteorological Organization (WMO) launched its Atlas of Mortality and Economic Losses from Weather, Climate and Water Extremes (1970–2019).  This publication presents information on the impacts of extreme weather, climate and water-related events that took place between 1970 and 2019.  It presents historic data on impacts provoked by storms, floods, droughts, extreme temperature, landslides, wildfires, and other hazards.  Impacts are expressed in terms of fatalities and economic losses. The publication benefitted from the contributions by the Centre for Research on the Epidemiology of Disasters (CRED), the World Health Organization (WHO) and Public Health England, and the United Nations Office for Disaster Risk Reduction (UNDRR).

    According to the Atlas, the ten worst disasters in terms of fatalities impacted Ethiopia, Bangladesh, Sudan, Myanmar, Mozambique, the Russian Federation, and the Bolivarian Republic of Venezuela.…
