We have finished 3-hourly radio sonde observation by 00Z December 8 and
started 6-hourly observation.
The followings are observational results of December 7.
Because wind speed was very weak under 10km height, balloon stayed near
the site less than 10km range. Then, we missed many PTU/WIND raw data
when balloon located just above (close to) the site.
--- Sonde observational report for December 7 ---
Day shift: Iyan and Bambang
Night shift: Hamada, Riris and Tanoue
00Z: Cloudy (8/8, Ci, Cu), 14.914km
03Z: Very Cloudy (6/8, 3Cu/Sc, 2Ac/As, 1Ci), 21.781km
06Z: Cloudy (5/8, 2Cu, 2Ac, 1Ci), 22.767km
09Z: Cloudy (4/8, 2Cu, 1Ac, 1Ci), 21.550km
12Z: Cloudy (4/8, 1Cu, 2Ac, 1Ci), 19.858km
# Wind EDT data were lost between 10.3km and 13.0km, because the raw
PTU/WIND signal was continuously weak when the balloon had returned to
above the site.
15Z: Cloudy (7/8, Ci, As, Ac), 19.179km
18Z: Cloudy (7/8, As, Ci), 18.992km
