Even peratures these problems had other causes and were not though v e g i = 8 ( d e s e r t) v e g i = ( ic e ) they revealed a code bug concerning the no vegetation related, sub-surface tile. As a consequence, the potential T ile lo w b e g e ta tio n v e g i = ( c r o p ) of soil type definitions in the other two subsurface insufficiencies tiles low vegetation and forest were discussed. v e g i = ( s h o r t g r a s s ) v e g i = 7 ( ta ll g r a s s ) v e g i = 9 ( tu n d r a ) v e g i = ( ir r ig a te d c r o p ) discussions took up the idea to refine the soil type se by utilizing the sub-surface type vegi in addi- determination to the FAO soil type not only under sub-surface tile no tion but also under low vegetation and forest (As vegetation, v e g i = ( s e m i- d e s e r t) v e g i = ( b o g /m a r s h ) v e g i = 6 ( e v e r g r e e n s h r u b ) A. in Bringfelt (996) shows, vegi has been utilized Table tile, but not in tiles and ). in v e g i = 7 ( d e c id u o u s s h r u b ) T ile fo re s t combination of using vegi and FAO soil type has potential to refine the ISBA soil type determination, the v e g i = ( e v e r g r e e n n e e d le tr e e ) v e g i = ( d e c id u o u s n e e d le tr e e ) v e g i = ( d e c id u o u s b r o a d le a f tr e e ) the vegetation type may give an indication on the because soil type. This way the crude information on soil underlying v e g i = 6 ( e v e r g r e e n b r o a d le a f tr e e ) v e g i = 8 ( m ix e d w o o d la n d ) in the FAO data can be enhanced by making use of type about the vegetation. information v e g i = 9 ( fo r e s t/fie ld s ) new mapping of FAO soil type and vegi into ISBA subsurface soil type is formulated in the list to the right, difference between the current and the new ISBA type determination in HIRLAM can be seen from the soil each of the three sub-surface tiles no vegetation (), low for () and forest (): vegetation pictures below.
