Data for the VALUE multi-variable experiment, extracted from the ECMWF Reanalysis ERA-Interim on February 3th 2016.

This dataset contains data for precipitation, temperatures, daily mean and maximum wind speed, relative humidity, and cloud cover of the nearest points of ERA-Interim to the twelve stations chosen for the multi-variable case study of Experiment 1a, as described in http://www.value-cost.eu/data.

The stations considered are a subset of VALUE_ECA_86 including twelve stations in Germany with daily data for precipitation, temperatures, daily mean wind speed, daily maximum wind speed, relative humidity, and cloud cover.

The data has been stored following the VALUE text format for station data http://www.value-cost.eu/WG2/stationdataformat and covers the period 1979-2008. 

Notes:
	- All the daily data has been obtained from the 6-hourly data by applying the corresponding function (e.g. mean for tmean, maximum for tmax and minimum for tmin).
	- Cloud cover has been obtained in octas from the original data, in the [0 1] interval, considering for each octa (0-8) all the values included in the interval (octa/8-1/16, octa/8+1/16) centered in the corresponding octa and with a width of 1/8.
	- Relative humidity is not included as direct output of the reanalysis and has been obtained from the mean temperature, dew point and surface pressure using the Clausius-Clapeyron equation.
	- In the case of the mean and maximum wind speed, first the 6-hourly wind speed has been obtained for the wind components (U and V) and, then, the daily mean and maximum has been estimated.
