Detecting Trends from our Records

In order to study drought we needed to build up a large archive of weather data and the reaction of the vegetation and rivers on the weather. This archive needs to be precise and cover at least the last 30 years and preferably longer. Our archive covers especially Summarized Monthly Rainfall, Daily Temperature, Soil Moisture, Low Flow and Vegetation activity.
One can use such an archive also to detect changes in these five parameters, both spatial and temporal. Whether the changes are statistically significant, in other words said, whether we can see from these data a climate change, is a discussion that we engage in in various articles. The data behind these discussions are made available from these pages. Please use them in an appropriate context, and although some results can be alarming, please use the data in a way in which th e complexity of our planet is respected and in a manner in which our curiosity and sense of responsibility for our fate can grow.

Analysis use as reference period 1981 to 2010, unless mentioned otherwise.
Analysis is limited to the European Territory of the member states of the European Union and their neighbors. The Koppen Climate Zone analysis includes also North West Africa, Turkey and parts of Russia.
Monthly Rainfall data are usually updated on the 4th of the month for the preceding month
Heat and Cold wave data are usually updated with two days delay.
Anomalies are computed per year, so the last year is not available, it will be made available around the 10th of January.
