Atmospheric Mass, Moisture, and Energy Budget products from NCEP Reanalysis at Tapered T42
NEW: It is highly recommended that users and prospective users of our Mass, Moisture and Energy Budget Products for NCEP Reanalysis see our recomputed and updated products at Vertically Integrated Mass, Moisture, Heat, and Energy Budget Products derived from the NCEP/NCAR Reanalysis, March 2003. Extensive background concerning the details of the derivation of these products can also be found on this new web page.
OLD: As of February 2002 Mass corrected fluxes for 1979-1998 are now avaialble. See below .

MASS CORRECTED FLUXES: Update and addition, February 2002
Mass corrected fluxes have been computed for the period 1979-1998
and are available online at
ftp://ftp/pub/CAS/TN4 30/NCEP/T42F/MASS_CORRECTED_FLUXES/. As before,
these are monthly means, monthly, seasonal, and annual climatologies and
standard deviations. Filename conventions are similar, the difference
being that a _CMC_ has been inserted as shown in the following list. The
units are the same, as well as the grid conventions (T42 Gaussian 128x64
Fortran unformatted direct access records, longitude beginning 0°E,
latitude S to N).
