Definition of the exercise

In any case, nonequilibrium spectra shall be calculated along with related local thermodynamic equilibrium spectra. Four different atmospheric models shall be considered, with highest priority on the midlatitude/day atmosphere.

Some parameters have not been defined but shall be chosen by each participant as considered appropriate (internal altitude grid; handling of lines outside the microwindow...).

The reason is that a lot of algorithms have automated parameter optimization facilities which shall not be by-passed or deactivated for this exercise.

Along with the equilibrium and nonequilibrium spectra please provide the following data which will be used for diagnostics:

Please provide radiance spectra in units of nW/(cm2 sr cm-1) as ASCII files and use the following data format

Calculated spectra should be put here

Results of this comparison will be published at IRS'2000 and possibly in a subsequent paper. If your contribution shall be published anonymous, please inform me; otherwise the origin of the data will be traceable in the publication.
