The Chinese Academy of Sciences has published a study in the Journal of Remote Sensing that introduces a hyperspectral remote sensing technique capable of hour-hectometer-level horizontal distribution of trace gases, offering an advanced tool to accurately identify emission sources. This technique uses effective optical paths (EOPs) within the ultraviolet (UV) and visible (VIS) spectral bands to measure average trace gas concentrations across various distances. A novel aspect of the study is the application of the onion-peeling method, which refines the data to reveal concentrations at specif ..read more

Francisco Obelenis, new business manager at Dualbase Tecnologia Eletrônica, spoke on Day 1 of  Meteorological Technology World Expo in Geneva, about ‘Smart sensors: a way to get better measurements’. The presentation began with Obelenis’s observation that although we have no control over the weather, we are able to measure it. Developing and implementing weather monitoring systems and alert systems is becoming crucial – and ensuring the reliability of these systems and the quality of the generated data is of the utmost importance. Smart sensors provide the solution by not only measuring ..read more

10M ago
Meteor Communications, a supplier of remote environmental monitoring systems, has been awarded a four-year £4m (US$5m) contract by the UK’s Environment Agency to expand its network of low-power remote image collection cameras. Installed at strategic locations across the country, the cameras will provide critically important information on the status of water management assets involved in reducing flood and coastal risk. Meteor will provide the agency with hourly images of remote assets such as grilles, screens, storm overflows, channels, culverts, pumps, gates and automated structures. The im ..read more

Finnish weather intelligence provider Skyfora has unveiled the world’s lightest weather sonde, the StreamSonde, developed with the help of the European Space Agency (ESA)’s Business Applications program. Weighing less than 15g, the StreamSonde can deliver weather intelligence by recording atmospheric flows, weather parameters and air quality in great detail. It has been designed to be launched from balloons, aircraft, drones or UAVs, and be carried by natural winds. By using GNSS technology and 3D motion sensors, it can record winds with a higher degree of accuracy and in greater detail than ..read more

NOAA study unveils impact of wildfire smoke on the stratosphere
Meteorological Technology International » Remote Sensing
by Dan Symonds
1y ago
A team of atmospheric scientists led by the US National Oceanic and Atmospheric Administration (NOAA) has demonstrated how large vertical plumes of wildfire smoke have a major long-term impact on the stratosphere and climate. Pyrocumulonimbus (pyroCb) are generated when the intense heat of a wildfire triggers a huge thunderstorm that carries smoke into the stratosphere, 8-11km above the surface. In 2017, the flight path of NASA’s Atmospheric Tomography Mission (ATom) intersected with smoke from the largest pyroCb event observed in the satellite era to that date over the Pacific Northwest. The ..read more

Earthquake sensors could be used to warn of flooding and damage potential
Meteorological Technology International » Remote Sensing
by Dan Symonds
1y ago
Seismic sensors already in place to detect earthquakes could sense floods and act as an early warning system to minimize damage and save lives, according to new research. Many floods in river valleys are monitored by river gauges, which can coarsely track a flood’s water level. However, gauges may be sparse, update infrequently and risk being washed away by a flood. Seismic stations are installed at a safe distance from streams and sense not only ground shaking due to earthquakes but also vibrations from explosions, landslides, storms and floods. Previous research into seismic flood monitorin ..read more

A research team from Russ College’s School of Electrical Engineering and Computer Science (EECS) at Ohio University has begun rolling out a network of ground-based sensors to create a low-altitude weather network (LAWN) in support of advanced air mobility (AAM) projects in the region. Chad Mourning, assistant professor at EECS, and his team completed the installation of the first sensor unit in August, with plans to install a further 25 units at the local airport. Mourning said, “We have an issue where we go to the Weather Channel and the satellite is telling you about the weather at 10,000ft ..read more

Vaisala sets out strategy for reducing Scope 3 emissions
Meteorological Technology International » Remote Sensing
by Dan Symonds
1y ago
Weather and environmental measurement specialist Vaisala has committed to setting a near-term science-based emissions reduction target aligned with the requirements of the UN-backed Science-Based Targets initiative (SBTi). Vaisala’s commitment includes decreasing its direct Scope 1 and indirect Scope 3 emissions by 2030. The more detailed target and methods to achieve it will be set based on calculations in 2022, after which the target will be sent to SBTi for validation in 2023. Kai Öistämö, president and CEO of Vaisala, said, “As the latest IPCC report states, climate change is an even more ..read more

NASA to develop hyperspectral microwave technology for dissecting boundary layer from space
Meteorological Technology International » Remote Sensing
by Dan Symonds
1y ago
US space agency NASA is developing new technologies to dissect the Earth’s planetary boundary layer (PBL), helping meteorologists to better understand the interaction between the Earth’s surface and weather, and its evolution in a changing climate. According to the agency, the PBL is the hardest part of the atmosphere to measure from space due to the volume of gases above it. Accurate, real-time measurement of PBL temperature and water vapor from space would help facilitate more accurate predictions of rapidly changing extreme weather events. Dr Antonia Gambacorta, research physical scientist ..read more
