Up to Transformations and interpolations
Hi, I have a problem with the bicubic and bilinear remapping with OASIS3-MCT_3.0. Here is my namcouple : CONSFTOT SONSHMED 1 86400 3 flxat.nc EXPOUT 116617 1 567 264 sfxc tm12 R 0 R 0 CHECKIN SCRIPR CHECKOUT INT=1 BILINEAR LR SCALAR LATLON 10 INT=1 And here is the error I get in the debug file for the bilinear interpolation : WARNING: Cannot make bilinear interpolation for target point 3764 Using non-masked points among 4 nearest neighbors. Point coords: 0.532838080368111 0.333401003708965 Dest grid info: 11610 0.532847577634110 0.333096607851711 T Dest grid info: 11611 0.532752880699299 0.335320969803918 T Dest grid info: 11611 0.532752880699299 0.335320969803918 T Dest grid info: 11610 0.532847577634110 0.333096607851711 T Current i,j : NaN NaN Iteration for i,j exceed max iteration count I do not understand the error. Could you explain what is going wrong ? Thanks, Best regards, Florence
Hi Florence, I had a look at your grids and sfxc is a logically rectangular grid (i,j). You must define it using both dimensions in i and j direction. You must put in your namcouple : FSENDANA FRECVANA 1 7200 3 rst.nc EXPOUT 432 288 567 264 sfxm tm12 If you put : 116617 1 567 264 sfxc tm12, it is as if sfxc was a gaussian reduced grid which is not the case and which is misleading for OASIS. Best regards, Laure
