  • The world is on fire: Wildfires rage in Greece

    The world is on fire: Wildfires rage in Greece

    One month after fire blazed through the Greek island of Rhodes in July 2023, more fires have ripped through Greece amid a heatwave in southern Europe, reported the European Space Agency (ESA).

    A Copernicus Sentinel-2 image (Figure 1) shows the ongoing blaze near Alexandroupoli in the Evros region of northeast Greece – close to the Türkiye border.

    The satellite image is a blend between a natural color and a shortwave infrared composite to highlight the fire front, which was approximately 70 km long as of August 23. The fire has produced a plume of smoke that stretched 1,600 km southwest towards Tunisia. Burned areas can be seen in the image in dark brown.

    The Copernicus Sentinel-2 mission is based on a constellation of two identical satellites, each carrying a wide swath high-resolution multispectral imager with 13 spectral bands for monitoring changes in the Earth’s land and vegetation.

    In response to the fires, the Copernicus Emergency Mapping Service has been activated in North Attica, Rodopi, Euboea Island, the Sterea Ellada Region, and East Macedonia. The service uses satellite observations to help civil protection authorities and the international humanitarian community respond efficiently to emergencies.

    Greece has experienced daily outbreaks of dozens of fires over the past week as gale-force winds and hot, dry summer conditions combined to whip up flames and hamper firefighting efforts. On August 26, firefighters tackled 122 fires, including 75 that broke out in the 24 hours between August 25 and August 26, the fire department (formally the Hellenic Fire Service) said.

    Scientists have warned that climate change and land-use changes are projected to make wildfires more frequent and intense. In response, the ESA has reopened its World Fire Atlas, which provides a detailed analysis and map of wildfires across the globe.

    The causes of Greece’s two largest fires have not yet been determined. For some of the smaller blazes, officials have said arson or negligence is suspected, and several people have been arrested, reported NBC News.

    2J Antennas has introduced the Stellar series, antennas designed for a large suite of devices with a focus on GNSS, sub-6 GHz, 5G NR, 4G LTE, 3G, 2G and WiFi-6E technologies.

    The Stellar Series is suitable for law enforcement, medical transportation, fire rescue and other applications where mission-critical communication is a requirement. The antennas are designed to reliably provide real-time connectivity in a small size.

    This series includes single or up to 9-in-1 configuration choices within the range of 617 MHz to 7125 MHz frequency bands.

    The patent-pending technology reduces the antenna footprint by 55% while implementing a new double trifilar design and longitudinal resonances for MIMO/ARRAY configurations that traditionally have more complex size restrictions (such as B71 band/600 MHz).

    Each antenna configuration uses symmetrical or asymmetrical resonators for negative sections of the antenna, resulting in maximum performance at low and mid frequencies. The Stellar series offers magnetic and adhesive mounting choices, making them suitable for temporary installations.

    For permanent installation, 2J Antennas also offers the screw mount option in its roof series. The low-profile and lightweight housing introduces a new design that offers a more cost-effective solution for suppliers and distributors.

    “We are excited to reinvent antenna designs to meet the fast-growing global markets and offer antenna solutions with the highest quality while reducing antenna sizes as much as possible,” said Ruben Cuadras, director of engineering. “We are proud to continue to bring antenna solutions to customers that require small device integration, reliability and new designs.”
