  • Serang Sounding Report - Feb 13 (Nighttime Duty)
    Dear all,

    Selamat pagi.

    We have performed all launches successfully. It was rainy just one hour before midnight. However, the rain stopped several minutes before 18 UTC, and we could continue the observation. In the morning, the weather was finally fine and the wind was calm, thus the balloon flew overhead at 00 UTC launch. All sonde reached maximum altitude around 21km.

    We didn't meet any major trouble during the observation.

    18 UTC :
    - launched at 00:25 LST, ended at 01:37 LST (SE)
    - maximum altitude of 20.9km
    - the weather was overcast, 7 oktas (Cu, St)

    00 UTC :
    - launched at 06:25 LST, ended at 07:40 LST (overhead)
    - maximum altitude of 21.7km
    - the weather was fine, 2 oktas (Ci, As, Ac)

    Anyway, it was my final duty (and report) for this IOP and i want to thank you for all support, guide, trust and invaluable experience during the observation period.

    Hontou ni arigatou gozaimashita.

    with best regards,

  • CDR CAPPI 2km Animation 12 Feb 2010 (11:00 - 23:54 LST)
    Dear all,

    I attached animation of CDR CAPPI image (2km) on Feb 12 2010, starting at 11:00 LST - 23:54 LST. As you could see, there was a heavy thunderstorm above Bogor area in the late afternoon (15-18 LST). Even though the rain had finally stopped around 20 LST, water overflow continued to reach Depok, Bekasi and Jakarta on Feb 13, at 2-3 LST and caused floods in several places in Jabodetabek area.

    best,

  • Serang Sounding Report : Feb 11 (nighttime duty)
    Dear all,

    Selamat pagi.

    We have launched radiosondes for 18 UTC and 00 UTC successfully. The only problem we faced was a malfunction transmitter during ground check for 18 UTC. The Pressure difference is too large (more than 2 hPa) and GC-25 rejected the transmitter, so we have to change it with the new one. Hence, we have only 1 transmitter spare remaining for Serang observation.
    The weather was fine, almost without clouds (1/8) and the surface wind was suprisingly calm (0 and 0.1 m/s, for each launch respectively). Both ballons flew overhead.

    18 UTC :
    - launched at 00:34 LST, ended at 01:40 LST
    - maximum altitude of 21.1km
    - the weather was fine, 1 okta (Ci, As)

    00 UTC :
    - launched at 06:30 LST, ended at 07.44 LST
    - maximum altitude of 19.9km
    - the weather was fine, 1 okta (Ci, Cs, As)

    with best regards,

Plan Position Indicator (PPI) adalah tampilan radar yang paling umum dikenal. Pada PPI, antena radar umumnya direpresentasikan sebagai titik pusat di layar, sehingga jarak dari titik pusat dan ketinggian dari atas permukaan tanah dapat digambarkan sebagai lingkaran konsentris. Pada saat antena berotasi, suatu jejak radial pada sapuan PPI akan disesuaikan dengan titik pusatnya.

Radar antenna mengirimkan sinyal pada saat berotasi 360 derajat dan dapat mengubah sudut serta mengulang rotasinya (elevasi dan azimuth) sesuai dengan kebutuhan. Sinyal pantul dari target akan diterima oleh antena dan diproses oleh penerima. Tampilan langsung dari proses inilah yang disebut sebagai PPI.
