Kanaly atmosferyczne mają ogromne znaczenie dla badań naukowych. Kanaly te mają tendencję do zakrzywiania sygnalów radiowych. Zastosowania oparte na propagacji sygnalów radiowych przez atmosferę są narażone na blędy i niedokladności. Zastosowania te mogą obejmowac wskazywanie satelitów, wykrywanie radarowe, identyfikację lokalizacji itp. W niniejszym badaniu zbadano tworzenie się kanalów troposferycznych i propagację sygnalów RF przez te kanaly nad Pakistanem, Indiami, Afganistanem i krajami pokrewnymi, wykorzystując dane z teledetekcji satelitarnej z okresu od stycznia 2009 r. do grudnia 2012 r. Istnienie kanalów nad dużymi obszarami Pakistanu stwierdzono w różnych miesiącach. W niniejszym badaniu omówiono pory roku występowania kanalów (wiosna, lato, jesień, zima). Duże kanaly zaobserwowano w listopadzie, a następnie w marcu i kwietniu. W październiku zaobserwowano minimalną liczbę kanalów. Większośc kanalów występuje w poludniowo-wschodniej części Pakistanu. W niniejszym badaniu omówiono również rodzaje kanalów w odniesieniu do propagacji fal. Przez caly okres badania w większości miesięcy występowaly kanaly superrefrakcyjne. Kanaly normalne i subrefrakcyjne zaobserwowano tylko w październiku. Omówiono również istnienie kanalów stalych nad badanymi obszarami.
