Target elements

Other elements used for feature extraction

Temperature on the ground

‘Temperature on the multiple isopiestic surfaces’ and ‘relative humidity and wind velocity on the ground and multiple isopiestic surfaces’

Relative humidity on the ground

‘relative humidity on the multiple isopiestic surfaces’ and ‘temperature and wind velocity on the ground and multiple isopiestic surfaces’

Wind velocity on the ground

‘Wind velocity on the multiple isopiestic surfaces’ and ‘temperature and relative humidity on the ground and multiple isopiestic surfaces’
