+**Copernicus Essential climate variables for assessment of climate variability from 1979 to present**
+=======================================================================================================
+
+This tool is a wrapper to retrieve Copernicus Essential Climate Variables.
+It corresponds to the European Contribution to the Monitoring of Essential Climate Variables from Space.
+An Essential Climate Variable is a physical, chemical or biological variable or a group of linked variables
+that critically contributes to the characterization of Earth’ s climate.
+
+The Essential Climate Variables for assessment of climate variability from 1979 to present dataset contains
+a selection of climatologies and monthly anomalies of Essential Climate Variables (ECVs) suitable for
+monitoring and assessment of climate variability and change. Selection criteria are based on accuracy
+and temporal consistency on monthly to decadal time scales. The ECV data products in this set have been
+estimated from multiple sources and, depending on the source, may have been adjusted to account for biases
+and other known deficiencies. Data sources and adjustment methods used are described in the Product User
+Guide, as are various particulars such as the baseline periods used to calculate monthly climatologies and
+the corresponding anomalies.
