- Monthly means and anomalies (relative to a 1981-2010 base period) are provided for six surface humidity variables (including specific and relative humidity) and temperature alongside uncertainty estimates (observation and grid box sampling). Utilizes simultaneous sub daily temperature and dew point temperature data from >4500 quality controlled and homogenized HadISD stations that have sufficiently long records. All humidity variables are calculated at hourly resolution and monthly means are created and next interpolated on a global grid.
