====== Results of SCORE-MIP radiative transfer model intercomparison ======


===== Intercomparison cases =====

|                      | b1 w1 Lambert| b1 w1 Ocean | b3 w2 Lambert | b3 w2 Ocean|
|low aerosol           |  1a  |  1b  |  1c  |  1d  |
|low aerosol + cirrus  |  2a  |  2b  |  2c  |  2d  |
|high aerosol          |  3a  |  3b  |  3c  |  3d  |
|high aerosol + cirrus |  4a  |  4b  |  4c  |  4d  |
|pure Rayleigh         |  5a  |  5b  |  5c  |  5d  |

The detailed setup can be found [[:intercomparisons:scoremip:setup|here]].

The [[:intercomparisons:scoremip:results:sron_acc|SRON results]] have been taken as the reference for the model intercomparison.


===== Model intercomparisons ===== 

=== Accurate setup ===
  * [[:intercomparisons:scoremip:results:cdisort|CDISORT]]
  * [[:intercomparisons:scoremip:results:mystic_acc|MYSTIC]]
  * [[:intercomparisons:scoremip:results:scia_acc|SCIATRAN]]
  * [[:intercomparisons:scoremip:results:oco_acc|OCO]]
  * [[:intercomparisons:scoremip:results:csu_acc|CSU]]
  * [[:intercomparisons:scoremip:results:nies_acc|NIES]]

=== Fast setup ===
  * [[:intercomparisons:scoremip:results:sron_fast|SRON]] 
  * [[:intercomparisons:scoremip:results:scia_fast|SCIATRAN]]
  * [[:intercomparisons:scoremip:results:oco_fast|OCO]]
  * [[:intercomparisons:scoremip:results:csu_fast|CSU]]

===== Discussion =====
  * BRDF/BPDF are not well defined for the intercomparison, all models should use the same. The results of CSU and NIES are very similar, would it be possible to provide this BPDF to all groups?    
  * I would like to compare I and Q separately, not only I-Q. This also allows to assess the error due to neglecting polarization
