Many customers of the WRMC are interested in radiation fluxes averaged over time series longer than one month. This can be performed within the WRMC using the so called Data Warehouse. The results from the Data Warehouse base always on the current data within PANGAEA which normally have a time resolution of one minute. The results are not precompiled! Thus, be patient, if you submit a Data Warehous query covering data from many years. Using the Data Warehouse to retrieve unaveraged long time series may result in huge data files. Try short time series first. The Data Warehouse produces arthmetic averages only. Please keep in mind that there exists many other averaging methods which lead to other results especially if applied to incomplete time series. This problem is described in detail by Roesch et al. 2011.
