NCEP Reanalysis Mass, Moisture, and Energy Budget Products
(includes products from NCAR Technical Note 430: Evaluation of the Atmospheric Moisture and Hydrological Cycle in the NCEP Reanalyses: Monthly Means and Summary Statistics.)
SPECIAL NOTE: A new archive has been made available at tapered T42
resolution that includes a more complete mass correction to the total,
dry static, and latent energy divergences. It was found that the
application of the old mass correction to these quantities resulted in
their no longer behaving as divergences; that is, when integrated over
a closed domain, they did not vanish. The products on this page remain
unchanged; the three divergence quantities are the old mass
corrected quantities. The new products are located at:
