ECMWF-15 Reanalysis: Summary

We have removed the ECMWF-15 dataset from our archive. If you need the data, you can obtain it from ECMWF and NCAR. Please let us know if this is a huge problem. Note that the ECMWF-40 reanalysis dataset uses a more recent model, has more years, and is higher resolution. You can get that from ECMWF and NCAR as well.
