Topik: Kontur for F2 Ketersediaan Perpustakaan Pusat (Semanggi) Nomor Panggil: WW32.1 Non-tandon: 1 (dapat dipinjam: 0) Tandon: tidak ada     Lihat Detail Induk Isi artikel The foF2 contour map of Middle Indonesia Region has been derived from the monthly median value of foF2 at Manado (1.48° N, 124.85° E) on September 1995. It based on assumption that the foF2 monthly median data of Manado represent data of 500 km radius area or 50 latitude from Manado. The foF2 measured by IPS-51 digital ionosonde, which has been operated since 15 of August 1995. The griding methods are Invers distance of Power, Kriging, Minimum curvature, and Shepard’s method which operated in SURFER contour map software. The results are five almost be the same contour maps except Invers distance of Power method. The results show a good correlation by 0.65 to 0.87. Further research to used transformation by model at equatorial latitude, which deviation this paper is 3.3 MHz maximum. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
