Quick Look

Mean vapor pressure was measured at all climate stations. It is an expression for humidity and can be used together with Temperature and pressure data to approximate relative humidity and cloud base level (assuming simplified pressure conditions) as has been done in the “derived data” section.

Looking at the time series of mean vapor pressure in figures 1a-c and 2a-c it is not apparent that humidity has droped during 1987 to 1999.
