I have also tried replacing the original data in WPS_GEOG using the convert_geotiff method, but I get the message "WPS_GEOG/lu_index/00001-00200.00001-00200, point (748, 214) has an invalid category of 0". However, the lu_index in the generated geo_em data has been successfully replaced, but LAI and others remain as 0. Do you have any suggestions? Thank you very much, and I look forward to your reply.
