What is TR

means there was a trace of water in the measuring instrument- it is used for values of rainfall

0<rainfall<0.05

We can clean data which means replacing ‘tr’ with either 0mm and 0.025mm

Typical range is from 10 to 360 degrees

multiples of 10 only

Which direction the wind is blowing from

Wind/gust direction ( cardinal)

Units- compass direction( N, SE, W)
