mozart.o3.128x64_L18_2000cyc_c040123.nc

were created by Gary Strand (strandwg@ucar.edu)

The original T42 ozone data was created by running the PCM, using input data
provided by Jean-Francois Lamarque (lamar@ucar.edu) and then feeding the output
into the MOZART model at 20 year intervals - 1890, 1910, 1930, 1950, 1970 and
1990.

The output at those intervals is available (as of Feb 2004) on the NCAR MSS
under /LAMAR/IPCC:

A linearly-interpolated monthly dataset using the six 20-year interval datasets
as endpoints. Each month was interpolated using the same month from the appro-
priate 20 year interval datasets (Jan 1920 is 0.5*Jan 1910 + 0.5*Jan 1930).
