Issue 1: A vampire's schedule Most of the AMiBA team's observational work takes place at night, because clouds and moisture are more likely to interfere with reception during daylight hours. At nightfall, the inversion layer drops to about 2,800 meters, where it is less likely to affect their research.
難題 1：晝伏夜出 AMiBA 研究團隊的星空觀測工作，多半在夜間進行，這是因為山上白天時氣溫較高，致使儀器雜訊較大，且日間也容易出現雲層、水氣等可能影響訊號接收的物質；傍晚雲層就會下降至 2,800 公尺左右的高度，較不會影響研究工作。
