PMIP4 CESM dust data
Data files
- each variable for each climate period is in a separate file. In the
conc
(dust concentration) case, which contains the three-dimensional dust concentration in the atmosphere, ancillary variables are also included in the same file, i.e. those necessary to fully describe the vertical coordinate (lev, ilev, hyai, hybi, hyam, hybm, PS) - file names =
PMIP4_DUST_Albani_<field>_<expt>.nc
field

=PI
(pre-Industrial),MH
(mid-Holocene) orLGM
(Last Glacial Maximum)- The gaussian weights file does not depend on the experiment:
PMIP4_DUST_Albani_gw.nc
Dimensions
- nb_time = 12
- 12 time steps in each file, corresponding to the climatological monthly averages (with the exception of
erod
, the soil erodibility variable), indicated as days since 2020-01-01 00:00:00. They are assumed to all have equal weight - time = [ 14, 44, 74, … 284, 314, 344 ]
- nb_lat, nb_lon = 192, 288 (0.95 x 1.25 degrees)
- latitude_values = [ -90, -89.05759, -88.11518, … 88.11518, 89.05759, 90 ]
- longitude_values = [ 0, 1.25, 2.5, … 356.25, 357.5, 358.75 ]
- size_bin = 4 (dust particle size classes)
- dust size bin edges = 0.1, 1.0, 2.5, 5.0, 10.0 μm (diameters)
- size values = [1, 2, 3, 4]

- nb_levels = 26 hybrid sigma-pressure levels
