Eradiate supports simulation using the correlated-k distribution method. To
that end, various data are used and shipped as part of the software package.
Bin set definitions are shipped in the form of NetCDF datasets. Below is the
minimal dataset structure required for Eradiate to be able to interpret bin
definitions data.
CKD quadrature points are shipped in the form of NetCDF datasets. Below is the
minimal dataset structure required for Eradiate to be able to interpret CKD
quadrature points data sets.
Coordinates (* means also dimension)
*z (float): altitude
Multi-level index *bd (int). Corresponding coordinates are stored as
NetCDF variables and data is reindexed upon loading:
bin[bd] (str): bin name
index[bd] (int): quadrature point index
Variables
k[z,bd] (float): quadrature point absorption coefficient value
[\(\text{length}^{-1}\)]
Metadata
bin_set (str): ID of the associated bin set
Note
The impact in terms of storage saved or lost is yet to be evaluated but we
consider it a minor concern. If this approach proves to be impractical, we
may consider modifying the data format.
