If we want a subset, for example, for Venezuela we need tiles: h10 h11 h12 v07 v08

cd $GISDATA/sensores/Modis/$VAR/$VRS

for FECHA in $(cat links)
do
  cd $GISDATA/sensores/$VAR/$VRS/$FECHA
  rm qry
  touch qry
  for h in h10 h11 h12; do for v in v07 v08;   do grep $h$v links >> qry; done ;done ;
  sort qry | uniq  > qry2
  wget -b --user=$EARTHDATAUSR --password=$EARTHDATAPWD --continue -i qry2 --base=${MFTP}${REPO}/${VAR}.${VRS}/${FECHA}/
