Up to Transformations and interpolations
Hi all, I am remapping a positive field from Arpege to NEMO but I have one negative value at lon=189, lat=85.5 on the interpolated field, which corresponds to i=100 and j=281 on NEMO. This point is far from the coast, not yet at the pole, but close to the line lon=0 on Arpege. If you have any idea of what is wrong ! Thanks, Aurore
Hi Aurore, Following Sophie advice, I had a look at the values of the longitudes of the corners for i=100 and j=281 : ncks -d y_tor1,280 -d x_tor1,99 -v tne1.clo grids.nc and below are the results : crn_tor1[0] y_tor1[280] x_tor1[99] tne1.clo[101459]=-174.674220032 degree_E crn_tor1[1] y_tor1[280] x_tor1[99] tne1.clo[207163]=-179.8744946 degree_E crn_tor1[2] y_tor1[280] x_tor1[99] tne1.clo[312867]=178.750864424 degree_E crn_tor1[3] y_tor1[280] x_tor1[99] tne1.clo[418571]=-176.455407546 degree_E There is a probleme with the third corner as there is a jump of 360 deg and OASIS can not manage that. You must recalculate the corners. Best regards, Laure
