Minute-by-minute air temperature readings at weather-station level.
These data are collected from automated weather instruments, and is automatically published as soon as it is generated. There could be instances when there are gaps in the data due to technical problems. The data is subject to correction subsequently if necessary.
While every effort has been made to site the instruments in relatively unobstructed areas to provide the best possible indication of the general weather conditions, there are times when this is not possible. The measurements from the instruments could thus be influenced by local conditions e.g., measurements at some coastal stations may be strongly influenced by the surrounding sea.
