using regrid

[Y. Yamasaki]

Gisele,

Eu instalei as rotinas do NCARG no diretorio
/usr/local/unidata/ncarg ou algo parecido no seu laptop.
Ha diversas rotinas do ncar/ncl que fazem interpolacoes.
--> inclusive sobre um que eu mencionei nas apresentacoes
(natgrid) Vide por exemplo :
http://www.ncl.ucar.edu/Document/Functions/Contributed/obj_anal_ic.shtml

para maiores detalhes.
Voce pode fazer uma interface em fortran e usar as rotinas
ncl (vide descricao no site da ncar).

Vou tenter ver algo mais voltado para o caso de voces.
