Atmospheric Mass, Moisture, and Energy Budget products from ECMWF 15-Year Reanalysis at Tapered T42

NOTICE: The FS files are being replaced. Do not use the the `old' FS files until this notice is updated. (The old FS files corresponded to FS derived from NCEP, not ERA-15. We acknowledge Matthew Peters and Chris Bretherton at the University of Washington for pointing this out to us.)
