Hi, I have juste started to work with the ARTS model and the qpack2 package to perform temperature and humidity retrievals.
I think I managed to run qpack2 for the temperature (I still have some problems with humidity). I have a loop over about 200 atmospheric profiles and I retrieve the temperature profile from these atmospheric profiles and the observation from a ground-based microwave radiometer. However for some profiles I have the following error that I do not understand: --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- arts: /home/martinet/RADIOMETRE/arts-2.0.41/src/interpolation.cc:202: void gridpos(ArrayOfGridPos&, ConstVectorView, ConstVectorView, const Numeric&): Assertion `is_increasing(old_grid)' failed. /home/martinet/RADIOMETRE/arts-2.0.41/build/src/arts -r00 /tmp/atmlab-martinet-tp897f84cb_6b6b_4953_bc99_95e5f8f4ad7f/cfile_y.arts: Aborted Error using arts (line 47) An error occured while executing ARTS. See above. Error in arts_oem (line 43) arts( cfile ); Error in oem (line 785) [R,yf] = feval( comfun, Q, R, x, iter ); Error in qpack2 (line 114) [X,R] = oem( O, Qm, R, @arts_oem, Sx, Se, Sxinv, [], xa, Y(m).Y ); Error in retrieval_profiles (line 132) L2 = qpack2( Q, O, Y ); ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- This message appears after at least one iteration. Does anyone know what is wrong? Thank you very much for your help. Best regards, Pauline ----- Météo-France ----- MARTINET PAULINE CNRM/GMEI/LISA [email protected] Fixe : +33 561079031
