Last change on this file since 1528 was 1528, checked in by idelkadi, 13 years ago

Les modificaions concerne la partie Lidar du simulateur COSP :

  1. Correction dans phys_cosp.F90 du bug sur le calcul des altitudes aux milieux et aux interfaces des couches
  2. Rajout du teste "Lidar parfait" (iflag_testlidar=.true. dans lidar_simulator.F90)
  3. Correction d'une erreur sur la dimension du tableau frac_out dans cosp_lidar.F90
  4. Sories sur les niveaux presnivs du modele dans le cas ou l'on desactive l'interpolation sur les 40 niveaux COSP

26! History:
27! Jul 2007 - A. Bodas-Salcedo - Initial version
28! Oct 2008 - S. Bony          - Instructions "Call for large-scale cloud" removed  -> sgx%frac_out is used instead.
29!                               Call lidar_simulator changed (lsca, gbx%cca and depol removed;
30!                               frac_out changed in sgx%frac_out)
