نقش و کاربرد داده‌های باند P ماهواره‌ی راداری Biomass آژانس فضایی اروپا در مدیریت جنگل

ماهواره راداری Biomass آژانس فضایی اروپا در اواخر ماه آپریل ۲۰۲۵ (۲۹ آپریل) به فضا پرتاب خواهد شد.

پس از قرارگیری در مدار و طی مراحل راه‌اندازی، مأموریت بیومس نقش مهمی در ارائه اطلاعات نوین درباره وضعیت جنگل‌های زمین، تغییرات آن‌ها در طول زمان و بهبود دانش از چرخه کربن ایفا خواهد کرد. این ماهواره نخستین نمونه‌ای است که رادار دهانه مصنوعی باند P با قابلیت پُلاریزاسیون کامل را برای تصویربرداری تداخلی به همراه دارد. با توجه به طول‌موج بلند باند P (حدود ۷۰ سانتی‌متر)، سیگنال راداری قادر است از لایه‌های جنگلی عبور کند و "زیست‌توده" را اندازه‌گیری کند، یعنی تنه‌های چوبی، شاخه‌ها و ساقه‌ها که بیشترین میزان کربن درختان در آن‌ها ذخیره می‌شود.

Telegram Be The Next Best SPAC

I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.
